OMB Control Number: 0575–0190. Type of Request: Extension of currently approved information collection. Abstract: The Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriation Act, 2006 (Pub. L. 109– 97) provides funding for, and authorizes Rural Development to conduct a demonstration program for the preservation and revitalization of the Section 515 Multi-Family Housing portfolio. Section 515 of the Housing Act of 1949 (42 U.S.C. 1485) provides Rural Development the authority to make loans for low-income MultiFamily Housing and related facilities. Rural Development refers to this program as Multifamily Preservation and Revitalization (MPR) Demonstration Program. A Notice of Solicitation for Applications (NOSA) sets forth the eligibility and application requirements. Information will be collected from applicants and grant recipients by Rural Development staff in its Local, Area, State, and National Offices. This information will be used to determine applicant eligibility for this demonstration program. If an applicant proposal is selected, that applicant will be notified of the selection and given the opportunity to submit a formal application. This MPR demonstration program continues to adjust the various opportunities available to demonstrate effective methods of providing the needed financial resources not otherwise available to current owners and transferees. Using alternative forms of financing, these owners will preserve existing Agency-financed Rural Rental Housing and Farm Labor Housing and extend the property’s useful life for tenants meeting RD eligibility requirements. Since the inception of the MPR demonstration program in 2006, revisions and adjustments in the nature of the program have necessitated certain revisions in the context, formatting and use of the original forms in this package to permit RD’s ability to provide these needed financial opportunities. To meet current Agency NOSA, regulatory and industry standards, the following forms are being revised, reformatted and/or renamed in some instances to provide clarity and consistency in their practical use and application: • MPR Pre-Application • Debt Deferral Agreement • Restrictive-Use Covenant • Restrictive-Use Subordination Agreement VerDate Sep<11>2014 20:49 Aug 19, 2019 Jkt 247001 • MPR Grant Agreement • MPR Loan and Grant Resolution (nonprofit corporation) • Restructuring Conditional Commitment (renamed: MPR Offer and Conditional Commitment) • Addendum to Debt Deferral Agreement • Subordination Agreement Estimate of Burden: Public reporting burden for this collection of information is estimated to average 1 hour per response.

SUPPLEMENTARY INFORMATION: jbell on DSK3GLQ082PROD with NOTICES I. Purpose The purpose of these advisory guidelines for onboard wheelchairs is to provide air carriers and onboard wheelchair manufacturers with technical assistance in meeting their obligations under the Air Carrier Access Act. 49 U.S.C. 41705. The Department of Transportation has indicated an intent to issue regulations under the Air Carrier Access Act that seek to implement the final resolution of a negotiated rulemaking, described in more detail below. See Resolution of the Department of Transportation Access Committee, Annex A (Nov. 22, 2016), available at https://www.transportation. gov/sites/dot.gov/files/docs/ACCESS CommitteeFinalResolution.11.21.16.pdf. The agreed-upon terms include a requirement for an onboard wheelchair of enhanced functionality on specified commercial aircraft of more than 125 passenger seats. The Department of Transportation has sought technical assistance from the Access Board in providing specifications that would meet a future mandatory performance standard, issued by the Department, for such onboard wheelchairs. Similar to the existing onboard wheelchair regulations at 14 CFR 382.65(c), it is expected that the new standards the Department of Transportation intends to issue as a result of the negotiated rulemaking will be performance standards. This means that the contemplated regulations would require onboard wheelchairs to have certain features and meet established functional criteria but would not specify technical requirements such as dimensions for specific features. The Access Board’s advisory guidelines would serve as technical assistance for covered air carriers, providing one example of how covered air carriers might satisfy the performance standard for onboard wheelchairs established by DOT in its forthcoming rulemaking. These advisory guidelines contain recommended dimensions and other VerDate Sep<11>2014 20:49 Aug 19, 2019 Jkt 247001 technical specifications that would help manufacturers optimize the design of a comfortable and functional chair and assist air carriers in the selection of onboard wheelchair models that best serve passengers with disabilities. Even if adopted by the Access Board, these guidelines will not be legally binding on any regulated entity. Whether or to what extent DOT subsequently references, incorporates, or adopts these guidelines falls under the department’s exclusive authority. Nonetheless, it is the Access Board’s understanding that DOT does not intend to issue any regulatory standards that would make nonconformance with these advisory guidelines a separate basis for affirmative enforcement action or imposition of administrative penalties. II. Background In 2016, the Department of Transportation established an Advisory Committee on Accessible Air Transportation (hereafter, ‘‘ACCESS Advisory Committee’’ or ‘‘Committee’’) to negotiate and develop a proposed rule concerning various accommodations for air travelers with disabilities, including the accessibility of lavatories on new single-aisle aircraft. See Nondiscrimination on the Basis of Disability in Air Travel; Establishment of a Negotiated Rulemaking Committee, 81 FR 20265 (Apr. 7, 2016). The Committee consisted of airline representatives, aircraft manufacturing representatives, representatives from disability rights advocacy organizations, and other stakeholders.1 The Committee agreed to specific incremental accessibility solutions with respect to aircraft lavatories. The accessibility solutions culminate in the requirement for installation on certain single-aisle aircraft of a lavatory of sufficient size to allow individuals with mobility disabilities to transfer from an onboard wheelchair to the toilet (and vice versa). However, by the terms of the Committee’s agreement, it will be at least twenty years before these lavatories are installed in single-aisle aircraft. See Resolution of the Department of Transportation Access Committee, Annex A (Nov. 22, 2016), available at https://www.transportation. gov/sites/dot.gov/files/docs/ACCESS CommitteeFinalResolution.11.21.16.pdf. In the interim, the Committee agreed to pursue improvements to the onboard wheelchairs that individuals with certain types of mobility disabilities 1 Full membership of the Committee can be viewed at DOT’s Notice of Negotiated Rulemaking (Reg-Neg) Committee Membership and Public Meeting, 81 FR 26178 (May 2, 2016). PO 00000 Frm 00003 Fmt 4703 Sfmt 4703 43101 must use to move between the aircraft seat and the lavatory. See Id. DOT currently requires air carriers to provide onboard wheelchairs on most aircraft with more than sixty passenger seats that have an accessible lavatory and when requested by a passenger with a disability even if the aircraft does not have an accessible lavatory. 14 CFR 382.65(b). DOT specifies certain features that onboard wheelchairs must have and performance criteria that they must meet. 14 CFR 382.65(c). Because of the general nature of these performance criteria, there is little standardization across manufacturers with respect to the design of onboard wheelchairs. The Committee agreed to pursue an onboard wheelchair design that, if feasible, could be positioned over a closed toilet to allow for better use of the other features of a lavatory, including the privacy afforded by a closed door. The Committee also acknowledged the existence of safety and usability challenges with traditional onboard wheelchair models. The Committee thus agreed that DOT should develop new standards for onboard wheelchairs, and that, in the future, certain aircraft 2 would be required to provide an onboard wheelchair that meets those standards. In response to the Committee’s agreement, DOT requested technical assistance from the Access Board in developing advisory guidelines that would address the Committee’s concerns. The Access Board proposes the below advisory guidelines in response to this request. III. Legal Authority The Air Carrier Access Act permits the Department of Transportation to seek assistance from the Access Board for the provision of ‘‘technical assistance to air carriers and individuals with disabilities in understanding the rights and responsibilities’’ under the Act. 49 U.S.C. 41705. In addition, Section 502 of the Rehabilitation Act of 1973, as amended, tasks the Access Board with statutory authorities relating to transportation barriers confronting persons with disabilities. See 29 U.S.C. 792. Specifically, the Board is directed to ‘‘investigate and examine alternative 2 By the terms of the ACCESS Committee’s final resolution, the new requirements for onboard wheelchairs would apply to ‘‘New covered single aisle aircraft with 125 FAA maximum certified passenger seats entering service 3 years after the effective date of the Final Rule.’’ Resolution of the U.S. Department of Transportation Access Committee, Annex A (Nov. 22, 2016), available at https://www.transportation.gov/sites/dot.gov/files/ docs/ACCESSCommitteeFinal Resolution.11.21.16.pdf.

Further, the Access Board is charged with promoting accessibility throughout all segments of society. Id. at (b)(4). IV. Discussion of Proposed Guidelines jbell on DSK3GLQ082PROD with NOTICES A. Design Considerations 1. Over-Toilet Position In these advisory guidelines, the Access Board proposes that the onboard wheelchair be designed such that it can fully enter the aircraft lavatory in a backward orientation, where the seat of the onboard wheelchair slides over the closed toilet allowing the lavatory door to be completely closed with the occupied onboard wheelchair inside. The purpose of allowing the onboard wheelchair to be positioned over the toilet is to provide both privacy and sufficient space for movement so that the occupant can accomplish nontoileting personal hygiene and medically needed tasks in private. In this use, the occupant is not using the toilet. In order to use the toilet, the onboard wheelchair occupant would need to transfer from the onboard wheelchair to the toilet, typically by standing and pivoting 180 degrees. Owing to the small size of lavatories on single-aisle aircraft, such a transfer is typically accomplished with the door to the lavatory open, and the onboard wheelchair partially or fully outside the lavatory. However, many people are unable to perform a stand-and-pivot transfer; the proposed over-toilet positioning would allow these individuals the opportunity to use the lavatory for non-toileting personal hygiene or medically needed tasks that require the privacy afforded by a closed lavatory door. Over-toilet positioning of the onboard wheelchair was of interest to the members of DOT’s ACCESS Advisory Committee and was included in the Committee’s final agreement to the extent that such a design is feasible. The Board seeks comment on whether such a design is feasible. The Board is not VerDate Sep<11>2014 20:49 Aug 19, 2019 Jkt 247001 aware of any commercially available onboard wheelchair that can be positioned over a toilet; however, researchers from Hamburg University of Applied Sciences (Germany) have been developing a prototype with a cantilever design that could be positioned over the toilet.3 The Board notes that any such design is ‘‘feasible’’ in this context only if it meets all other technical requirements (including collapsibility for storage) and does not involve modification of the aircraft lavatory. Question 1. Is it feasible to design an onboard wheelchair that can be positioned over a toilet without modification to the aircraft lavatory? Please explain the design and engineering considerations that would impact the ability of the onboard wheelchair to maneuver over the toilet. Question 2. If feasible, would this onboard wheelchair also be capable of folding and being stored in an FAAcertified stowage space? Question 3. What are the cost implications associated with the design and manufacture of an onboard wheelchair that can be positioned over a toilet without modification to the aircraft lavatory? 2. Loads The loads that commercially available onboard wheelchairs support vary widely. For example, the overall weight capacity of currently available models varies from approximately 200 to 800 pounds. In the Access Board’s 1987 publication Guidelines for Aircraft Boarding Chairs,4 we recommended that seats support at least 723 pounds (weight of a 99th percentile male with a 3.0 safety factor). See https:// www.access-board.gov/research/ completed-research/guidelines-foraircraft-boarding-chairs. Using updated anthropometrics, the weight of a 99th 3 The prototype developed by Hamburg University features a hole in the seat of the onboard wheelchair so that an occupant could remain in the onboard wheelchair while using the toilet. These guidelines do not contemplate such a use for the onboard wheelchair, as these guidelines call for the onboard wheelchair to be positioned over a closed toilet. We reference the Hamburg University design for its over-toilet positioning capability. 4 After receiving reports of accidents and near accidents involving the use of aircraft boarding chairs, the Access Board sought public comment on the development of voluntary standards for boarding chairs. 49 FR 36210 (Sep. 14, 1984). Based on public comments and various other research, the Board published a proposed advisory standard in 1986 that contained technical specifications for chairs used to board and deplane individuals with mobility disabilities. 51 FR 17762 (May 15, 1986). The Board published the final technical paper, Guidelines for Aircraft Boarding Chairs in 1987. The FAA subsequently adopted portions of the guidelines in its Advisory Circular on Aircraft Boarding Equipment, AC No: 150/5220–21C (6/29/ 2012). PO 00000 Frm 00004 Fmt 4703 Sfmt 4703 percentile male with a 3.0 safety factor would be 826 pounds. See Department of Health and Human Service Centers for Disease Control and Prevention’s Anthropometric Reference Data for Children and Adults: United States, 2011–2014, Table 6, Line 1 (Aug. 2016). SAE International, in its standard Foldable On-Board Wheelchairs for Passengers with Disabilities, ARP 4120C (Stabilized 2013), requires a different overall load. In the proposed guidelines, the Board reserves provisions for loads related to the seat, arm supports, foot support, casters, and assist handles, pending further information as to what loads are appropriate for an onboard wheelchair design that accomplishes the proposed functions. Specifically, the Board is unaware of any existing industry standards for onboard wheelchairs that are designed to allow over-the-toilet positioning, and therefore does not propose incorporation by reference of the loads of any existing standard, including the loads from the Board’s 1987 Guidelines for Aircraft Boarding Chairs, absent further engineering information. Question 4. If the over-the-toilet positioning is feasible, what should the respective loads be for the seat, arm supports, foot support, casters, and assist handles? Question 5. If the over-the-toilet positioning is not feasible, what should the respective loads be for the seat, arm supports, foot support, casters, and assist handles? B. Section 1: Application and Administration In the proposed guidelines, Section 1 establishes the purpose and the general requirements for application of the onboard wheelchair guidelines. 101.1 Purpose The purpose of these technical specifications is to provide technical assistance for the design of an onboard wheelchair with enhanced safety and stability, and that improves the ability of persons with mobility disabilities to have access to and use of the lavatory for toileting and non-toileting privacy needs, such as administering medication or conducting hygiene related tasks in a safe manner. 101.2 Voluntary Application These Advisory Guidelines for Aircraft Onboard Wheelchairs establish voluntary, non-binding technical guidance for use by airlines and manufacturers of onboard wheelchairs. E:\FR\FM\20AUN1.SGM 20AUN1 Federal Register / Vol. 84, No. 161 / Tuesday, August 20, 2019 / Notices 101.3 Dimensions These technical specifications take into consideration adult anthropometrics. For anthropometrics, the Board consulted data from the Department of Transportation Federal Aviation Administration Human Factors Design Standard, HF–STD–001B (Dec. 30, 2016), and the Department of Health and Human Services Centers for Disease Control and Prevention’s Anthropometric Reference Data for Children and Adults: United States, 2011–2014 (Aug. 2016). In addition, due to the lack of available updated anthropometrics on feet and seated hip breadth, the Board used data from our 1987 Guidelines for Aircraft Boarding Chairs (which references Wesley Woodson’s 1981 Human Factors Design Handbook). The dimensions of the onboard wheelchair must also account for the aircraft dimensions necessary to ensure that the onboard wheelchair fits through the aisle of the aircraft, into the lavatory, and over the toilet. We therefore seek information on the relevant aircraft measurements necessary to determine the appropriate dimensions of an onboard wheelchair that can fully enter an aircraft lavatory and be positioned over the toilet. Question 6. Is there recent anthropometric data on adult male feet and seated hip breadth that the Access Board should consider? Question 7. Please provide information on aisle width for singleaisle aircraft with more than 125 passenger seats. Question 8. Please provide dimensions for lavatories on single-aisle aircraft with more than 125 passenger seats, including: Width of the doorway opening, height of the lavatory doorway threshold, interior width and depth of the lavatory, clear floor space aside the toilet, and available clearances below the toilet bowl. 101.4 Dimensional Tolerances jbell on DSK3GLQ082PROD with NOTICES Dimensions are subject to conventional industry tolerances for manufacturing processes, material properties, and field conditions. Question 9. What information or resources are available concerning conventional industry tolerances for manufactured equipment such as onboard wheelchairs? 102 Definitions The following terms are defined in the advisory guidelines: Attendant, caster, and onboard wheelchair. These advisory guidelines rely on the definition of other terms as defined by regulations issued VerDate Sep<11>2014 20:49 Aug 19, 2019 Jkt 247001 by the Department of Transportation under the Air Carrier Access Act. All other terms should be given their ordinary accepted meaning as implied by the context in which the term is used. Question 10. What other terms, if any, should be defined in this section? C. Section 2 Technical Specifications 201.1 Occupied Movement The technical criteria in 201.1 address the required functionality of an onboard wheelchair while occupied by a passenger. The onboard wheelchair must be designed such that it can move both forward and backward through the aisle of the aircraft. The purpose of requiring movement in both directions is to ensure that a forward entry into a lavatory for transfer, as well as a backward entry into the lavatory if the occupant intends to remain in the onboard wheelchair while inside the lavatory, is possible. Question 11. What concerns are there, if any, about a design that allows for the onboard wheelchair to be maneuvered in both a forward approach and a backward approach to the lavatory? 201.1.1 Lavatory Transfer The purpose of this provision is to ensure that the onboard wheelchair can be maneuvered close enough to the lavatory toilet in a forward orientation such that an occupant who is capable of a stand-and-pivot transfer is able to transfer to the toilet. In a forward approach to the lavatory, the attendant would push the onboard wheelchair partially into the lavatory using the rear assist handles. Once close enough to the toilet for transfer, the attendant or occupant would apply the wheel locks, and the occupant would then stand and pivot to transfer to the toilet.5 201.1.2 Over-Toilet Positioning The purpose of this requirement is to ensure that the onboard wheelchair can successfully maneuver into the lavatory and over the closed toilet in a manner that permits the lavatory door to close completely, providing the occupant with privacy. In this use, the attendant would push the onboard wheelchair backward into the lavatory using the assist handles on the front of the chair. 5 The ACCESS Advisory Committee’s agreement indicates that specified aircraft would be required to provide a visual barrier to be used where the door to the lavatory must remain open during transfer. See Resolution of the Department of Transportation Access Committee, Annex A (Nov. 22, 2016), available at https:// www.transportation.gov/sites/dot.gov/files/docs/ ACCESSCommitteeFinalResolution.11.21.16.pdf. PO 00000 Frm 00005 Fmt 4703 Sfmt 4703 43103 The attendant would push the onboard wheelchair over the closed toilet, which would permit the lavatory door to close completely. Question 12. What space constraints exist within aircraft lavatories that would prevent the onboard wheelchair from completely entering the lavatory? Question 13. Are there any protruding objects inside aircraft lavatories that would impede over-toilet positioning? If so, please describe the protruding objects. 201.2 Unoccupied Movement When folded, the onboard wheelchair must be maneuverable on its wheels to allow an attendant to transport and stow an unoccupied onboard wheelchair without having to carry it. Question 14. The Access Board is aware that, in practice, unoccupied onboard wheelchairs are sometimes carried by an attendant as opposed to being pushed on their own wheels. Should the onboard wheelchair be required to be maneuverable on its own wheels when unoccupied? 202 Stowage The onboard wheelchair must be collapsible for stowage in one of the spaces certified by the FAA for stowage of onboard wheelchairs (such as a closet or overhead luggage compartment). Question 15. What are the FAAcertified stowage spaces on commercial passenger aircraft with over 125 passenger seats, and what are their respective dimensions? Question 16. Would these proposed technical specifications result in an onboard wheelchair that will fit in at least one of the FAA-certified spaces for onboard wheelchair stowage? If not, how should the specifications be altered so that the onboard wheelchair will fit into such spaces? 203 Stability This provision requires the onboard wheelchair to be stable throughout transport and transfer of the occupant. The purpose of this provision is to ensure that the onboard wheelchair will not tip or fall in any direction during use, which could result in injury to the occupant, attendant, or other passengers. Question 17. What are the stability concerns regarding existing onboard wheelchair models? Question 18. Would a design for overtoilet positioning affect the stability of the onboard wheelchair? Please explain. Question 19. What additional requirements, if any, could be provided to ensure that the onboard wheelchair is stable during use? E:\FR\FM\20AUN1.SGM 20AUN1 43104 Federal Register / Vol. 84, No. 161 / Tuesday, August 20, 2019 / Notices 204 Surface Hazards The purpose of this provision is to reduce the risk of injury by requiring that the onboard wheelchair be free from sharp or abrasive components and have eased edges. Sharp edges or abrasive elements may cause a direct contact injury or result in an occupant or attendant losing his or her grip during positioning or transfer. 205 Instructions In order to ensure the proper operation of the onboard wheelchair, the operation instructions must be prominently displayed. Providing instructions on the onboard wheelchair itself will ensure that any attendant using it will have access to the instructions and understand its proper operation. jbell on DSK3GLQ082PROD with NOTICES 206.1 (Seat) Height For ease of transfer, the seat height of the onboard wheelchair should be as close to the height of the aircraft seat as possible to permit lateral transfer. See The Impact of Transfer Setup on the Performance of Independent Transfers: Final Report, https://www.herl.pitt.edu/ ab/. The Access Board seeks information on aircraft passenger seat heights and aircraft toilet heights. In the Board’s Americans with Disabilities Act (ADA) Accessibility Guidelines for Buildings and Facilities, 36 CFR part 1191, and ADA Accessibility Guidelines for Transportation Vehicles, 36 CFR part 1192, we have routinely required a fixed height of 17 to 19 inches for transfer surfaces (See e.g., 36 CFR 1191, Appendix D, 604.4 (toilet seat), 610.2 (bathtub seats), 610.3 (shower compartment seats), and 903.5 (benches) and 36 CFR 1192.107 and 1192.123 (toilet seat in commuter and intercity rail cars). We are unable to propose a seat height without further information regarding the height of passenger seats and the height of aircraft toilets.6 Question 20. What is the height of seats on single aisle aircraft with more than 125 passenger seats? Please provide the airline, the type of aircraft, class of seating (if there is a difference among classes), and the height of the seats measured from the floor to the 6 The ACCESS Committee’s Agreed Term Sheet indicates that ‘‘Tier 1’’ aircraft will be required to have a lavatory with a toilet height of 17 to 19 inches. Resolution of the Department of Transportation Access Committee, Annex A (Nov. 22, 2016). If this provision is implemented by the Department of Transportation, the Access Board, with additional information regarding the height of a closed toilet lid, could specify an appropriate height for the onboard wheelchair seat. However, because that requirement has not yet been implemented, the Access Board seeks information on existing aircraft toilet dimensions. VerDate Sep<11>2014 20:49 Aug 19, 2019 Jkt 247001 uncompressed top of the cushion or padding. Question 21. Please provide the following dimensions of the height of aircraft toilets: Height of the bowl measured from the floor; height of the toilet seat measured from the rim of the bowl; and height of the closed toilet seat lid measured from the surface upon which it sits. Question 22. What are the design and engineering considerations of an onboard wheelchair with an adjustable seat height? 206.2 (Seat) Size and 206.3 Padding The seat size of the onboard wheelchair is restricted by the width of the aircraft aisle and the doorway opening of the aircraft lavatory. The purpose of this provision is to provide access to the largest number of individuals with disabilities, while also ensuring the onboard wheelchair can function as intended. We propose a seat size of at least 15 inches wide and at least 16 inches deep. These dimensions are consistent with the size required in our Guidelines for Aircraft Boarding Chairs. See https://www.accessboard.gov/research/completed-research/ guidelines-for-aircraft-boarding-chairs 1987. In that technical paper, we opined that the ‘‘narrowest part of the aircraft aisle is generally at the aircraft seat armrest’’ and is 17 inches. Id. at 22. Additionally, we referenced Wesley Woodson’s 1981 Human Factors Design Handbook, which noted that the 95th percentile male seat width was 15.9 inches. Id. Based on both the confines of the aircraft dimensions and human factors, we have determined that 15 inches wide is still a valid width requirement for the onboard wheelchair. Additionally, the Board is proposing that the onboard wheelchair seat be padded or cushioned to preserve skin integrity, minimize injury, prevent spasticity, and provide greater safety and comfort. Question 23. What recent human factors research provides data on seated hip breadth for the 95th percentile male? Question 24. On single-aisle aircraft with more than 125 passenger seats, is there any part of the aircraft aisle that is narrower than 17 inches through which the onboard wheelchair would need to pass to transport a passenger from her seat to the lavatory? Question 25. What are the cost implications, if any, of the proposed seat size? 207 Back Support In determining the proposed height for the onboard wheelchair’s back PO 00000 Frm 00006 Fmt 4703 Sfmt 4703 support, we looked to the current Department of Transportation Federal Aviation Administration Human Factors Design Standard, which indicates that the 95th percentile male for shoulder sitting height is 25.4 inches and the shoulder sitting height for a 5th percentile female is 20 inches. HF– STD001B (Dec. 30, 2016). These measurements reveal an increase in shoulder height from the dimensions used in the Access Board’s 1987 Guidelines for Boarding Chairs, which recommended a minimum back support height of 25 inches.7 Based on this updated anthropometric information, we are proposing that the onboard wheelchair back support be a minimum of 26 inches high above the seat. In addition, we are proposing to allow a gap of no more than 2 inches between the surface of the seat and the bottom of the back support. The purpose of this specification is to ensure that the backrest is positioned low enough to provide support to the occupant, while allowing manufacturing flexibility needed to ensure that the chair can be folded for stowage. Question 26. Is a two-inch gap between the seat and the back support sufficiently large to allow the chair to be folded? Question 27. It is important that the onboard wheelchair provide sufficient trunk support to the occupant. Should these guidelines specify a minimum width for the back support? If so, what should the recommended width be? Question 28. Should these guidelines specify a requirement for head and neck support? What are the design implications of adding head and neck support? Would the onboard wheelchair’s functionality be affected? 208.1 (Arm Support) Length and 208.2 (Arm Support) Position and Securement The Board proposes a requirement of two repositionable arm supports. The purpose of the arm supports on the onboard wheelchair is to provide transfer support to persons using the onboard wheelchair and to allow occupants seated in the chair to reposition themselves. In addition, the arm supports allow onboard wheelchair occupants to stabilize themselves during transport. While both arm supports may be used simultaneously for transfer into and out of the front of the onboard wheelchair, a side transfer from or to an aircraft seat will require the repositioning of one of the arm 7 At that time, the Access Board relied on anthropometrics from Wesley Woodson’s Human Factors Design Handbook (1981) indicating a shoulder height of 25 inches for 95th percentile males and 18 inches for 5th percentile females. E:\FR\FM\20AUN1.SGM 20AUN1 Federal Register / Vol. 84, No. 161 / Tuesday, August 20, 2019 / Notices supports. For example, if the occupant is transferring into the onboard wheelchair from the left side of the chair, the arm support on the left side of the chair would be repositioned so as not to obstruct the transfer and the occupant would use the arm support on the right side to assist with transfer. The proposed length of these supports is 15 inches. The proposed length is based on anthropometrics of elbow-grip length, which is the horizontal distance from the back of the elbow to the center of the clenched fist: 15.4 inches for 95th percentile males and 11.8 inches for 5th percentile females. Department of Transportation Federal Aviation Administration Human Factors Design Standard, HF–STD–001B, 5.12.3.2.1.23 (Dec. 30, 2016). Question 29. Should these guidelines specify a width and shape for the armrests in order to achieve the purpose of this provision? If so, what armrest width and shape would be optimal to provide support during transfer and repositioning? jbell on DSK3GLQ082PROD with NOTICES 209.1 (Foot Support) Size and 209.2 Position and Securement The purpose of the foot support is to provide support and stability for the occupant’s feet and legs during transport, as well as to assist the occupant with repositioning and transferring. In determining the appropriate size of the foot support, we considered anthropometric data of the human foot size. As noted above, we were unable to locate recent anthropometric data on feet, and thus relied on data from Wesley Woodson’s 1981 Human Factors Design Handbook, which we referenced in our Guidelines for Aircraft Boarding Chairs (1987). This research indicates a foot breadth of 4.3 inches and foot length of 11.2 inches for 95th percentile males and a foot breadth of 3.2 inches and foot length of 8.7 inches for 5th percentile females. Based on this information, and taking into consideration additional space for footwear, the Access Board proposes a unitary foot support that is a minimum of 9 inches wide and 12 inches deep. The unitary support allows for more stability as both feet move together. Further, the unitary support design requires fewer moving parts. Finally, the foot support must be repositionable so as not to obstruct transfer to or from the side or front of the onboard wheelchair. Question 30. Is the proposed size of the foot support sufficient to provide a stable support for both feet? Question 31. Do the proposed design, size, and repositionability of the foot support present any design or VerDate Sep<11>2014 20:49 Aug 19, 2019 Jkt 247001 engineering concerns? Please describe those concerns, if any. Question 32. Should the footrest fold in a specific direction, such as up or off to one side? If so, what direction should be specified and why? 209.3 (Foot Support) Threshold Clearance The Access Board proposes that the bottom of the foot support be at least 0.75 inches higher than the highest point of the lavatory doorway threshold. The purpose of this provision is to ensure that the onboard wheelchair can easily and safely maneuver over the lavatory threshold to enter the lavatory in both a forward and backward approach. Question 33. Are there any other barriers besides the lavatory threshold that would require the foot support to clear a specific height? 210.1 (Caster) Swivel Locks and 210.2 Wheel Locks The Board proposes that onboard wheelchairs have independent caster wheels for maximum maneuverability in the tight spaces of an aircraft cabin and lavatory. For safety and stability, the Board proposes that each caster provide a swivel lock and a wheel lock. The purpose of the swivel locks is to allow an attendant to lock the wheels in position for linear movement, providing greater stability and directional control as the attendant pushes the chair down the aisle. The wheel locks ensure the onboard wheelchair can be secured in a static position for transfer or for use inside the lavatory. Question 34. Should these guidelines specify a size of the caster wheels? If so, what size wheel would ensure stability of the onboard wheelchair and allow the chair to easily traverse the lavatory doorway threshold? Question 35. What would be the cost implications of a requirement that the caster wheels have a five-inch diameter? Question 36. Is it necessary for safety and stability that each caster have a swivel lock? Would swivel locks on two wheels be sufficient? Please explain. Question 37. Please explain the design and engineering considerations involved in the provision of a wheel lock system that engages each caster wheel. What are the safety concerns with a chair that has locks on only two caster wheels? Question 38. What are the engineering and design implications of a requirement for the swivel and wheel locks to be operable by the occupant? Question 39. What effect on stability, if any, results from a requirement that all wheels be independent casters? PO 00000 Frm 00007 Fmt 4703 Sfmt 4703 43105 Question 40. Is it necessary for maneuverability that each wheel of the onboard wheelchair be an independent caster? Could an onboard wheelchair easily maneuver through the aisle and into the lavatory in both a forward and backward approach with fewer casters? If so, which wheels should be required to be independent casters and why? 211.1 Rear Assist Handles The purpose of the rear assist handles is to allow the attendant to push or pull the occupied onboard wheelchair through the aircraft aisle. In addition, the attendant may use the rear assist handles to maneuver the onboard wheelchair into the lavatory in a forward orientation. Question 41. Is it necessary for the rear assist handles to be repositionable to allow for over-toilet positioning of the onboard wheelchair? 211.2 Front Assist Handles The purpose of the front assist handles is to allow the attendant to maneuver the occupied onboard wheelchair into the lavatory in a backward approach, position the onboard wheelchair over the toilet, and maneuver the onboard wheelchair out of the lavatory. The front assist handles must be capable of being repositioned so as not to obstruct transfer. The Board envisions that these assist handles would be attached to the onboard wheelchair at seat or knee height, similar to the design of some current models of aircraft boarding chairs. Question 42. Are there any existing onboard wheelchairs that have front assist handles? If so, where are the assist handles located? Question 43. Are there any engineering or design concerns regarding front assist handles? 212 Restraints This provision requires that the onboard wheelchair be equipped with both torso and leg restraints. The torso restraints are intended to secure the upper and lower torso of the occupant in the onboard wheelchair and the leg restraints are intended to maintain the legs of the occupant in the correct position during transport. The purpose of these restraints is to keep the occupant securely seated in the chair and prevent injury during transport through the aircraft. These restraints must be designed such that they can be repositioned so as not to obstruct transfer of the occupant to or from the onboard wheelchair. The fastening mechanisms of the restraints must be operable by the occupant so that the occupant may fasten the restraints E:\FR\FM\20AUN1.SGM 20AUN1 43106 Federal Register / Vol. 84, No. 161 / Tuesday, August 20, 2019 / Notices unassisted if desired. Finally, the restraints must be durable. The Access Board is aware of durability issues related to certain types of fasteners, such as hook-and-loop strip fasteners. The Board seeks comment on whether a specific type of fastener should be specified (or prohibited) by these guidelines. Question 44. Are additional restraints needed to ensure safe use of the onboard wheelchair? Question 45. Is it feasible to provide retractable restraints that auto-adjust (similar to the retractable seatbelts in cars)? Question 46. Should specific types of fasteners be required or prohibited to ensure durability? For the reasons stated in this notice, the Board proposes Advisory Guidelines for Aircraft Onboard Wheelchairs as follows: Advisory Guidelines for Aircraft Onboard Wheelchairs Section 1: General jbell on DSK3GLQ082PROD with NOTICES 101 General 101.1 Purpose.

SUPPLEMENTARY INFORMATION:

I. Purpose

The purpose of these advisory guidelines for onboard wheelchairs is
to provide air carriers and onboard wheelchair manufacturers with
technical assistance in meeting their obligations under the Air Carrier
Access Act. 49 U.S.C. 41705. The Department of Transportation has
indicated an intent to issue regulations under the Air Carrier Access
Act that seek to implement the final resolution of a negotiated
rulemaking, described in more detail below. See Resolution of the
Department of Transportation Access Committee, Annex A (Nov. 22, 2016),
available at https://www.transportation.gov/sites/dot.gov/files/docs/ACCESSCommitteeFinalResolution.11.21.16.pdf. The agreed-upon terms
include a requirement for an onboard wheelchair of enhanced
functionality on specified commercial aircraft of more than 125
passenger seats. The Department of Transportation has sought technical
assistance from the Access Board in providing specifications that would
meet a future mandatory performance standard, issued by the Department,
for such onboard wheelchairs.
Similar to the existing onboard wheelchair regulations at 14 CFR
382.65(c), it is expected that the new standards the Department of
Transportation intends to issue as a result of the negotiated
rulemaking will be performance standards. This means that the
contemplated regulations would require onboard wheelchairs to have
certain features and meet established functional criteria but would not
specify technical requirements such as dimensions for specific
features. The Access Board's advisory guidelines would serve as
technical assistance for covered air carriers, providing one example of
how covered air carriers might satisfy the performance standard for
onboard wheelchairs established by DOT in its forthcoming rulemaking.
These advisory guidelines contain recommended dimensions and other
technical specifications that would help manufacturers optimize the
design of a comfortable and functional chair and assist air carriers in
the selection of onboard wheelchair models that best serve passengers
with disabilities. Even if adopted by the Access Board, these
guidelines will not be legally binding on any regulated entity. Whether
or to what extent DOT subsequently references, incorporates, or adopts
these guidelines falls under the department's exclusive authority.
Nonetheless, it is the Access Board's understanding that DOT does not
intend to issue any regulatory standards that would make non-
conformance with these advisory guidelines a separate basis for
affirmative enforcement action or imposition of administrative
penalties.

II. Background

In 2016, the Department of Transportation established an Advisory
Committee on Accessible Air Transportation (hereafter, ``ACCESS
Advisory Committee'' or ``Committee'') to negotiate and develop a
proposed rule concerning various accommodations for air travelers with
disabilities, including the accessibility of lavatories on new single-
aisle aircraft. See Nondiscrimination on the Basis of Disability in Air
Travel; Establishment of a Negotiated Rulemaking Committee, 81 FR 20265
(Apr. 7, 2016). The Committee consisted of airline representatives,
aircraft manufacturing representatives, representatives from disability
rights advocacy organizations, and other stakeholders.\1\
---------------------------------------------------------------------------

\1\ Full membership of the Committee can be viewed at DOT's
Notice of Negotiated Rulemaking (Reg-Neg) Committee Membership and
Public Meeting, 81 FR 26178 (May 2, 2016).
---------------------------------------------------------------------------

The Committee agreed to specific incremental accessibility
solutions with respect to aircraft lavatories. The accessibility
solutions culminate in the requirement for installation on certain
single-aisle aircraft of a lavatory of sufficient size to allow
individuals with mobility disabilities to transfer from an onboard
wheelchair to the toilet (and vice versa). However, by the terms of the
Committee's agreement, it will be at least twenty years before these
lavatories are installed in single-aisle aircraft. See Resolution of
the Department of Transportation Access Committee, Annex A (Nov. 22,
2016), available at https://www.transportation.gov/sites/dot.gov/files/docs/ACCESSCommitteeFinalResolution.11.21.16.pdf.
In the interim, the Committee agreed to pursue improvements to the
onboard wheelchairs that individuals with certain types of mobility
disabilities must use to move between the aircraft seat and the
lavatory. See Id. DOT currently requires air carriers to provide
onboard wheelchairs on most aircraft with more than sixty passenger
seats that have an accessible lavatory and when requested by a
passenger with a disability even if the aircraft does not have an
accessible lavatory. 14 CFR 382.65(b). DOT specifies certain features
that onboard wheelchairs must have and performance criteria that they
must meet. 14 CFR 382.65(c). Because of the general nature of these
performance criteria, there is little standardization across
manufacturers with respect to the design of onboard wheelchairs. The
Committee agreed to pursue an onboard wheelchair design that, if
feasible, could be positioned over a closed toilet to allow for better
use of the other features of a lavatory, including the privacy afforded
by a closed door. The Committee also acknowledged the existence of
safety and usability challenges with traditional onboard wheelchair
models. The Committee thus agreed that DOT should develop new standards
for onboard wheelchairs, and that, in the future, certain aircraft \2\
would be required to provide an onboard wheelchair that meets those
standards.
---------------------------------------------------------------------------

\2\ By the terms of the ACCESS Committee's final resolution, the
new requirements for onboard wheelchairs would apply to ``New
covered single aisle aircraft with 125 FAA maximum certified
passenger seats entering service 3 years after the effective date of
the Final Rule.'' Resolution of the U.S. Department of
Transportation Access Committee, Annex A (Nov. 22, 2016), available
at https://www.transportation.gov/sites/dot.gov/files/docs/ACCESSCommitteeFinalResolution.11.21.16.pdf.
---------------------------------------------------------------------------

In response to the Committee's agreement, DOT requested technical
assistance from the Access Board in developing advisory guidelines that
would address the Committee's concerns. The Access Board proposes the
below advisory guidelines in response to this request.

III. Legal Authority

The Air Carrier Access Act permits the Department of Transportation
to seek assistance from the Access Board for the provision of
``technical assistance to air carriers and individuals with
disabilities in understanding the rights and responsibilities'' under
the Act. 49 U.S.C. 41705.
In addition, Section 502 of the Rehabilitation Act of 1973, as
amended, tasks the Access Board with statutory authorities relating to
transportation barriers confronting persons with disabilities. See 29
U.S.C. 792. Specifically, the Board is directed to ``investigate and
examine alternative

[[Page 43102]]

approaches to the architectural, transportation, communication, and
attitudinal barriers confronting individuals with disabilities,
particularly with respect to telecommunications devices, public
buildings and monuments, parks and parklands, public transportation
(including air, water, and surface transportation, whether interstate,
foreign, intrastate, or local), and residential and institutional
housing,'' and to ``ensure that public conveyances, including rolling
stock, are readily accessible to, and usable by, individuals with
physical disabilities.'' Id. at 792(b)(5) and (b)(10). Further, the
Access Board is charged with promoting accessibility throughout all
segments of society. Id. at (b)(4).

IV. Discussion of Proposed Guidelines

A. Design Considerations

1. Over-Toilet Position
In these advisory guidelines, the Access Board proposes that the
onboard wheelchair be designed such that it can fully enter the
aircraft lavatory in a backward orientation, where the seat of the
onboard wheelchair slides over the closed toilet allowing the lavatory
door to be completely closed with the occupied onboard wheelchair
inside. The purpose of allowing the onboard wheelchair to be positioned
over the toilet is to provide both privacy and sufficient space for
movement so that the occupant can accomplish non-toileting personal
hygiene and medically needed tasks in private. In this use, the
occupant is not using the toilet. In order to use the toilet, the
onboard wheelchair occupant would need to transfer from the onboard
wheelchair to the toilet, typically by standing and pivoting 180
degrees. Owing to the small size of lavatories on single-aisle
aircraft, such a transfer is typically accomplished with the door to
the lavatory open, and the onboard wheelchair partially or fully
outside the lavatory. However, many people are unable to perform a
stand-and-pivot transfer; the proposed over-toilet positioning would
allow these individuals the opportunity to use the lavatory for non-
toileting personal hygiene or medically needed tasks that require the
privacy afforded by a closed lavatory door.
Over-toilet positioning of the onboard wheelchair was of interest
to the members of DOT's ACCESS Advisory Committee and was included in
the Committee's final agreement to the extent that such a design is
feasible. The Board seeks comment on whether such a design is feasible.
The Board is not aware of any commercially available onboard wheelchair
that can be positioned over a toilet; however, researchers from Hamburg
University of Applied Sciences (Germany) have been developing a
prototype with a cantilever design that could be positioned over the
toilet.\3\ The Board notes that any such design is ``feasible'' in this
context only if it meets all other technical requirements (including
collapsibility for storage) and does not involve modification of the
aircraft lavatory.
---------------------------------------------------------------------------

\3\ The prototype developed by Hamburg University features a
hole in the seat of the onboard wheelchair so that an occupant could
remain in the onboard wheelchair while using the toilet. These
guidelines do not contemplate such a use for the onboard wheelchair,
as these guidelines call for the onboard wheelchair to be positioned
over a closed toilet. We reference the Hamburg University design for
its over-toilet positioning capability.
---------------------------------------------------------------------------

Question 1. Is it feasible to design an onboard wheelchair that can
be positioned over a toilet without modification to the aircraft
lavatory? Please explain the design and engineering considerations that
would impact the ability of the onboard wheelchair to maneuver over the
toilet.
Question 2. If feasible, would this onboard wheelchair also be
capable of folding and being stored in an FAA-certified stowage space?
Question 3. What are the cost implications associated with the
design and manufacture of an onboard wheelchair that can be positioned
over a toilet without modification to the aircraft lavatory?
2. Loads
The loads that commercially available onboard wheelchairs support
vary widely. For example, the overall weight capacity of currently
available models varies from approximately 200 to 800 pounds. In the
Access Board's 1987 publication Guidelines for Aircraft Boarding
Chairs,\4\ we recommended that seats support at least 723 pounds
(weight of a 99th percentile male with a 3.0 safety factor). See
https://www.access-board.gov/research/completed-research/guidelines-for-aircraft-boarding-chairs. Using updated anthropometrics, the weight
of a 99th percentile male with a 3.0 safety factor would be 826 pounds.
See Department of Health and Human Service Centers for Disease Control
and Prevention's Anthropometric Reference Data for Children and Adults:
United States, 2011-2014, Table 6, Line 1 (Aug. 2016). SAE
International, in its standard Foldable On-Board Wheelchairs for
Passengers with Disabilities, ARP 4120C (Stabilized 2013), requires a
different overall load. In the proposed guidelines, the Board reserves
provisions for loads related to the seat, arm supports, foot support,
casters, and assist handles, pending further information as to what
loads are appropriate for an onboard wheelchair design that
accomplishes the proposed functions. Specifically, the Board is unaware
of any existing industry standards for onboard wheelchairs that are
designed to allow over-the-toilet positioning, and therefore does not
propose incorporation by reference of the loads of any existing
standard, including the loads from the Board's 1987 Guidelines for
Aircraft Boarding Chairs, absent further engineering information.
---------------------------------------------------------------------------

\4\ After receiving reports of accidents and near accidents
involving the use of aircraft boarding chairs, the Access Board
sought public comment on the development of voluntary standards for
boarding chairs. 49 FR 36210 (Sep. 14, 1984). Based on public
comments and various other research, the Board published a proposed
advisory standard in 1986 that contained technical specifications
for chairs used to board and deplane individuals with mobility
disabilities. 51 FR 17762 (May 15, 1986). The Board published the
final technical paper, Guidelines for Aircraft Boarding Chairs in
1987. The FAA subsequently adopted portions of the guidelines in its
Advisory Circular on Aircraft Boarding Equipment, AC No: 150/5220-
21C (6/29/2012).
---------------------------------------------------------------------------

Question 4. If the over-the-toilet positioning is feasible, what
should the respective loads be for the seat, arm supports, foot
support, casters, and assist handles?
Question 5. If the over-the-toilet positioning is not feasible,
what should the respective loads be for the seat, arm supports, foot
support, casters, and assist handles?

B. Section 1: Application and Administration

In the proposed guidelines, Section 1 establishes the purpose and
the general requirements for application of the onboard wheelchair
guidelines.
101.1 Purpose
The purpose of these technical specifications is to provide
technical assistance for the design of an onboard wheelchair with
enhanced safety and stability, and that improves the ability of persons
with mobility disabilities to have access to and use of the lavatory
for toileting and non-toileting privacy needs, such as administering
medication or conducting hygiene related tasks in a safe manner.
101.2 Voluntary Application
These Advisory Guidelines for Aircraft Onboard Wheelchairs
establish voluntary, non-binding technical guidance for use by airlines
and manufacturers of onboard wheelchairs.

[[Page 43103]]

101.3 Dimensions
These technical specifications take into consideration adult
anthropometrics. For anthropometrics, the Board consulted data from the
Department of Transportation Federal Aviation Administration Human
Factors Design Standard, HF-STD-001B (Dec. 30, 2016), and the
Department of Health and Human Services Centers for Disease Control and
Prevention's Anthropometric Reference Data for Children and Adults:
United States, 2011-2014 (Aug. 2016). In addition, due to the lack of
available updated anthropometrics on feet and seated hip breadth, the
Board used data from our 1987 Guidelines for Aircraft Boarding Chairs
(which references Wesley Woodson's 1981 Human Factors Design Handbook).
The dimensions of the onboard wheelchair must also account for the
aircraft dimensions necessary to ensure that the onboard wheelchair
fits through the aisle of the aircraft, into the lavatory, and over the
toilet. We therefore seek information on the relevant aircraft
measurements necessary to determine the appropriate dimensions of an
onboard wheelchair that can fully enter an aircraft lavatory and be
positioned over the toilet.
Question 6. Is there recent anthropometric data on adult male feet
and seated hip breadth that the Access Board should consider?
Question 7. Please provide information on aisle width for single-
aisle aircraft with more than 125 passenger seats.
Question 8. Please provide dimensions for lavatories on single-
aisle aircraft with more than 125 passenger seats, including: Width of
the doorway opening, height of the lavatory doorway threshold, interior
width and depth of the lavatory, clear floor space aside the toilet,
and available clearances below the toilet bowl.
101.4 Dimensional Tolerances
Dimensions are subject to conventional industry tolerances for
manufacturing processes, material properties, and field conditions.
Question 9. What information or resources are available concerning
conventional industry tolerances for manufactured equipment such as
onboard wheelchairs?
102 Definitions
The following terms are defined in the advisory guidelines:
Attendant, caster, and onboard wheelchair. These advisory guidelines
rely on the definition of other terms as defined by regulations issued
by the Department of Transportation under the Air Carrier Access Act.
All other terms should be given their ordinary accepted meaning as
implied by the context in which the term is used.
Question 10. What other terms, if any, should be defined in this
section?

C. Section 2 Technical Specifications

201.1 Occupied Movement
The technical criteria in 201.1 address the required functionality
of an onboard wheelchair while occupied by a passenger. The onboard
wheelchair must be designed such that it can move both forward and
backward through the aisle of the aircraft. The purpose of requiring
movement in both directions is to ensure that a forward entry into a
lavatory for transfer, as well as a backward entry into the lavatory if
the occupant intends to remain in the onboard wheelchair while inside
the lavatory, is possible.
Question 11. What concerns are there, if any, about a design that
allows for the onboard wheelchair to be maneuvered in both a forward
approach and a backward approach to the lavatory?
201.1.1 Lavatory Transfer
The purpose of this provision is to ensure that the onboard
wheelchair can be maneuvered close enough to the lavatory toilet in a
forward orientation such that an occupant who is capable of a stand-
and-pivot transfer is able to transfer to the toilet.
In a forward approach to the lavatory, the attendant would push the
onboard wheelchair partially into the lavatory using the rear assist
handles. Once close enough to the toilet for transfer, the attendant or
occupant would apply the wheel locks, and the occupant would then stand
and pivot to transfer to the toilet.\5\
---------------------------------------------------------------------------

\5\ The ACCESS Advisory Committee's agreement indicates that
specified aircraft would be required to provide a visual barrier to
be used where the door to the lavatory must remain open during
transfer. See Resolution of the Department of Transportation Access
Committee, Annex A (Nov. 22, 2016), available at https://www.transportation.gov/sites/dot.gov/files/docs/ACCESSCommitteeFinalResolution.11.21.16.pdf.
---------------------------------------------------------------------------

201.1.2 Over-Toilet Positioning
The purpose of this requirement is to ensure that the onboard
wheelchair can successfully maneuver into the lavatory and over the
closed toilet in a manner that permits the lavatory door to close
completely, providing the occupant with privacy. In this use, the
attendant would push the onboard wheelchair backward into the lavatory
using the assist handles on the front of the chair. The attendant would
push the onboard wheelchair over the closed toilet, which would permit
the lavatory door to close completely.
Question 12. What space constraints exist within aircraft
lavatories that would prevent the onboard wheelchair from completely
entering the lavatory?
Question 13. Are there any protruding objects inside aircraft
lavatories that would impede over-toilet positioning? If so, please
describe the protruding objects.
201.2 Unoccupied Movement
When folded, the onboard wheelchair must be maneuverable on its
wheels to allow an attendant to transport and stow an unoccupied
onboard wheelchair without having to carry it.
Question 14. The Access Board is aware that, in practice,
unoccupied onboard wheelchairs are sometimes carried by an attendant as
opposed to being pushed on their own wheels. Should the onboard
wheelchair be required to be maneuverable on its own wheels when
unoccupied?
202 Stowage
The onboard wheelchair must be collapsible for stowage in one of
the spaces certified by the FAA for stowage of onboard wheelchairs
(such as a closet or overhead luggage compartment).
Question 15. What are the FAA-certified stowage spaces on
commercial passenger aircraft with over 125 passenger seats, and what
are their respective dimensions?
Question 16. Would these proposed technical specifications result
in an onboard wheelchair that will fit in at least one of the FAA-
certified spaces for onboard wheelchair stowage? If not, how should the
specifications be altered so that the onboard wheelchair will fit into
such spaces?
203 Stability
This provision requires the onboard wheelchair to be stable
throughout transport and transfer of the occupant. The purpose of this
provision is to ensure that the onboard wheelchair will not tip or fall
in any direction during use, which could result in injury to the
occupant, attendant, or other passengers.
Question 17. What are the stability concerns regarding existing
onboard wheelchair models?
Question 18. Would a design for over-toilet positioning affect the
stability of the onboard wheelchair? Please explain.
Question 19. What additional requirements, if any, could be
provided to ensure that the onboard wheelchair is stable during use?

[[Page 43104]]

204 Surface Hazards
The purpose of this provision is to reduce the risk of injury by
requiring that the onboard wheelchair be free from sharp or abrasive
components and have eased edges. Sharp edges or abrasive elements may
cause a direct contact injury or result in an occupant or attendant
losing his or her grip during positioning or transfer.
205 Instructions
In order to ensure the proper operation of the onboard wheelchair,
the operation instructions must be prominently displayed. Providing
instructions on the onboard wheelchair itself will ensure that any
attendant using it will have access to the instructions and understand
its proper operation.
206.1 (Seat) Height
For ease of transfer, the seat height of the onboard wheelchair
should be as close to the height of the aircraft seat as possible to
permit lateral transfer. See The Impact of Transfer Setup on the
Performance of Independent Transfers: Final Report, https://www.herl.pitt.edu/ab/. The Access Board seeks information on aircraft
passenger seat heights and aircraft toilet heights. In the Board's
Americans with Disabilities Act (ADA) Accessibility Guidelines for
Buildings and Facilities, 36 CFR part 1191, and ADA Accessibility
Guidelines for Transportation Vehicles, 36 CFR part 1192, we have
routinely required a fixed height of 17 to 19 inches for transfer
surfaces (See e.g., 36 CFR 1191, Appendix D, 604.4 (toilet seat), 610.2
(bathtub seats), 610.3 (shower compartment seats), and 903.5 (benches)
and 36 CFR 1192.107 and 1192.123 (toilet seat in commuter and intercity
rail cars). We are unable to propose a seat height without further
information regarding the height of passenger seats and the height of
aircraft toilets.\6\
---------------------------------------------------------------------------

\6\ The ACCESS Committee's Agreed Term Sheet indicates that
``Tier 1'' aircraft will be required to have a lavatory with a
toilet height of 17 to 19 inches. Resolution of the Department of
Transportation Access Committee, Annex A (Nov. 22, 2016). If this
provision is implemented by the Department of Transportation, the
Access Board, with additional information regarding the height of a
closed toilet lid, could specify an appropriate height for the
onboard wheelchair seat. However, because that requirement has not
yet been implemented, the Access Board seeks information on existing
aircraft toilet dimensions.
---------------------------------------------------------------------------

Question 20. What is the height of seats on single aisle aircraft
with more than 125 passenger seats? Please provide the airline, the
type of aircraft, class of seating (if there is a difference among
classes), and the height of the seats measured from the floor to the
uncompressed top of the cushion or padding.
Question 21. Please provide the following dimensions of the height
of aircraft toilets: Height of the bowl measured from the floor; height
of the toilet seat measured from the rim of the bowl; and height of the
closed toilet seat lid measured from the surface upon which it sits.
Question 22. What are the design and engineering considerations of
an onboard wheelchair with an adjustable seat height?
206.2 (Seat) Size and 206.3 Padding
The seat size of the onboard wheelchair is restricted by the width
of the aircraft aisle and the doorway opening of the aircraft lavatory.
The purpose of this provision is to provide access to the largest
number of individuals with disabilities, while also ensuring the
onboard wheelchair can function as intended. We propose a seat size of
at least 15 inches wide and at least 16 inches deep. These dimensions
are consistent with the size required in our Guidelines for Aircraft
Boarding Chairs. See https://www.access-board.gov/research/completed-research/guidelines-for-aircraft-boarding-chairs 1987. In that
technical paper, we opined that the ``narrowest part of the aircraft
aisle is generally at the aircraft seat armrest'' and is 17 inches. Id.
at 22. Additionally, we referenced Wesley Woodson's 1981 Human Factors
Design Handbook, which noted that the 95th percentile male seat width
was 15.9 inches. Id. Based on both the confines of the aircraft
dimensions and human factors, we have determined that 15 inches wide is
still a valid width requirement for the onboard wheelchair.
Additionally, the Board is proposing that the onboard wheelchair seat
be padded or cushioned to preserve skin integrity, minimize injury,
prevent spasticity, and provide greater safety and comfort.
Question 23. What recent human factors research provides data on
seated hip breadth for the 95th percentile male?
Question 24. On single-aisle aircraft with more than 125 passenger
seats, is there any part of the aircraft aisle that is narrower than 17
inches through which the onboard wheelchair would need to pass to
transport a passenger from her seat to the lavatory?
Question 25. What are the cost implications, if any, of the
proposed seat size?
207 Back Support
In determining the proposed height for the onboard wheelchair's
back support, we looked to the current Department of Transportation
Federal Aviation Administration Human Factors Design Standard, which
indicates that the 95th percentile male for shoulder sitting height is
25.4 inches and the shoulder sitting height for a 5th percentile female
is 20 inches. HF-STD001B (Dec. 30, 2016). These measurements reveal an
increase in shoulder height from the dimensions used in the Access
Board's 1987 Guidelines for Boarding Chairs, which recommended a
minimum back support height of 25 inches.\7\ Based on this updated
anthropometric information, we are proposing that the onboard
wheelchair back support be a minimum of 26 inches high above the seat.
In addition, we are proposing to allow a gap of no more than 2 inches
between the surface of the seat and the bottom of the back support. The
purpose of this specification is to ensure that the backrest is
positioned low enough to provide support to the occupant, while
allowing manufacturing flexibility needed to ensure that the chair can
be folded for stowage.
---------------------------------------------------------------------------

\7\ At that time, the Access Board relied on anthropometrics
from Wesley Woodson's Human Factors Design Handbook (1981)
indicating a shoulder height of 25 inches for 95th percentile males
and 18 inches for 5th percentile females.
---------------------------------------------------------------------------

Question 26. Is a two-inch gap between the seat and the back
support sufficiently large to allow the chair to be folded?
Question 27. It is important that the onboard wheelchair provide
sufficient trunk support to the occupant. Should these guidelines
specify a minimum width for the back support? If so, what should the
recommended width be?
Question 28. Should these guidelines specify a requirement for head
and neck support? What are the design implications of adding head and
neck support? Would the onboard wheelchair's functionality be affected?
208.1 (Arm Support) Length and 208.2 (Arm Support) Position and
Securement
The Board proposes a requirement of two repositionable arm
supports. The purpose of the arm supports on the onboard wheelchair is
to provide transfer support to persons using the onboard wheelchair and
to allow occupants seated in the chair to reposition themselves. In
addition, the arm supports allow onboard wheelchair occupants to
stabilize themselves during transport. While both arm supports may be
used simultaneously for transfer into and out of the front of the
onboard wheelchair, a side transfer from or to an aircraft seat will
require the repositioning of one of the arm

[[Page 43105]]

supports. For example, if the occupant is transferring into the onboard
wheelchair from the left side of the chair, the arm support on the left
side of the chair would be repositioned so as not to obstruct the
transfer and the occupant would use the arm support on the right side
to assist with transfer.
The proposed length of these supports is 15 inches. The proposed
length is based on anthropometrics of elbow-grip length, which is the
horizontal distance from the back of the elbow to the center of the
clenched fist: 15.4 inches for 95th percentile males and 11.8 inches
for 5th percentile females. Department of Transportation Federal
Aviation Administration Human Factors Design Standard, HF-STD-001B,
5.12.3.2.1.23 (Dec. 30, 2016).
Question 29. Should these guidelines specify a width and shape for
the armrests in order to achieve the purpose of this provision? If so,
what armrest width and shape would be optimal to provide support during
transfer and repositioning?
209.1 (Foot Support) Size and 209.2 Position and Securement
The purpose of the foot support is to provide support and stability
for the occupant's feet and legs during transport, as well as to assist
the occupant with repositioning and transferring. In determining the
appropriate size of the foot support, we considered anthropometric data
of the human foot size. As noted above, we were unable to locate recent
anthropometric data on feet, and thus relied on data from Wesley
Woodson's 1981 Human Factors Design Handbook, which we referenced in
our Guidelines for Aircraft Boarding Chairs (1987). This research
indicates a foot breadth of 4.3 inches and foot length of 11.2 inches
for 95th percentile males and a foot breadth of 3.2 inches and foot
length of 8.7 inches for 5th percentile females. Based on this
information, and taking into consideration additional space for
footwear, the Access Board proposes a unitary foot support that is a
minimum of 9 inches wide and 12 inches deep. The unitary support allows
for more stability as both feet move together. Further, the unitary
support design requires fewer moving parts. Finally, the foot support
must be repositionable so as not to obstruct transfer to or from the
side or front of the onboard wheelchair.
Question 30. Is the proposed size of the foot support sufficient to
provide a stable support for both feet?
Question 31. Do the proposed design, size, and repositionability of
the foot support present any design or engineering concerns? Please
describe those concerns, if any.
Question 32. Should the footrest fold in a specific direction, such
as up or off to one side? If so, what direction should be specified and
why?
209.3 (Foot Support) Threshold Clearance
The Access Board proposes that the bottom of the foot support be at
least 0.75 inches higher than the highest point of the lavatory doorway
threshold. The purpose of this provision is to ensure that the onboard
wheelchair can easily and safely maneuver over the lavatory threshold
to enter the lavatory in both a forward and backward approach.
Question 33. Are there any other barriers besides the lavatory
threshold that would require the foot support to clear a specific
height?
210.1 (Caster) Swivel Locks and 210.2 Wheel Locks
The Board proposes that onboard wheelchairs have independent caster
wheels for maximum maneuverability in the tight spaces of an aircraft
cabin and lavatory. For safety and stability, the Board proposes that
each caster provide a swivel lock and a wheel lock. The purpose of the
swivel locks is to allow an attendant to lock the wheels in position
for linear movement, providing greater stability and directional
control as the attendant pushes the chair down the aisle. The wheel
locks ensure the onboard wheelchair can be secured in a static position
for transfer or for use inside the lavatory.
Question 34. Should these guidelines specify a size of the caster
wheels? If so, what size wheel would ensure stability of the onboard
wheelchair and allow the chair to easily traverse the lavatory doorway
threshold?
Question 35. What would be the cost implications of a requirement
that the caster wheels have a five-inch diameter?
Question 36. Is it necessary for safety and stability that each
caster have a swivel lock? Would swivel locks on two wheels be
sufficient? Please explain.
Question 37. Please explain the design and engineering
considerations involved in the provision of a wheel lock system that
engages each caster wheel. What are the safety concerns with a chair
that has locks on only two caster wheels?
Question 38. What are the engineering and design implications of a
requirement for the swivel and wheel locks to be operable by the
occupant?
Question 39. What effect on stability, if any, results from a
requirement that all wheels be independent casters?
Question 40. Is it necessary for maneuverability that each wheel of
the onboard wheelchair be an independent caster? Could an onboard
wheelchair easily maneuver through the aisle and into the lavatory in
both a forward and backward approach with fewer casters? If so, which
wheels should be required to be independent casters and why?
211.1 Rear Assist Handles
The purpose of the rear assist handles is to allow the attendant to
push or pull the occupied onboard wheelchair through the aircraft
aisle. In addition, the attendant may use the rear assist handles to
maneuver the onboard wheelchair into the lavatory in a forward
orientation.
Question 41. Is it necessary for the rear assist handles to be
repositionable to allow for over-toilet positioning of the onboard
wheelchair?
211.2 Front Assist Handles
The purpose of the front assist handles is to allow the attendant
to maneuver the occupied onboard wheelchair into the lavatory in a
backward approach, position the onboard wheelchair over the toilet, and
maneuver the onboard wheelchair out of the lavatory. The front assist
handles must be capable of being repositioned so as not to obstruct
transfer. The Board envisions that these assist handles would be
attached to the onboard wheelchair at seat or knee height, similar to
the design of some current models of aircraft boarding chairs.
Question 42. Are there any existing onboard wheelchairs that have
front assist handles? If so, where are the assist handles located?
Question 43. Are there any engineering or design concerns regarding
front assist handles?
212 Restraints
This provision requires that the onboard wheelchair be equipped
with both torso and leg restraints. The torso restraints are intended
to secure the upper and lower torso of the occupant in the onboard
wheelchair and the leg restraints are intended to maintain the legs of
the occupant in the correct position during transport. The purpose of
these restraints is to keep the occupant securely seated in the chair
and prevent injury during transport through the aircraft. These
restraints must be designed such that they can be repositioned so as
not to obstruct transfer of the occupant to or from the onboard
wheelchair. The fastening mechanisms of the restraints must be operable
by the occupant so that the occupant may fasten the restraints

[[Page 43106]]

unassisted if desired. Finally, the restraints must be durable. The
Access Board is aware of durability issues related to certain types of
fasteners, such as hook-and-loop strip fasteners. The Board seeks
comment on whether a specific type of fastener should be specified (or
prohibited) by these guidelines.
Question 44. Are additional restraints needed to ensure safe use of
the onboard wheelchair?
Question 45. Is it feasible to provide retractable restraints that
auto-adjust (similar to the retractable seatbelts in cars)?
Question 46. Should specific types of fasteners be required or
prohibited to ensure durability?
For the reasons stated in this notice, the Board proposes Advisory
Guidelines for Aircraft Onboard Wheelchairs as follows:

Advisory Guidelines for Aircraft Onboard Wheelchairs

Section 1: General

101 General
