The FAA dispute resolution procedures encourage the parties to protests and contract disputes to use ADR as the primary means to resolve protests and contract disputes, pursuant to the Administrative Dispute Resolution Act of 1996, Public Law 104–320, 5 U.S.C. 570–579, and Department of Transportation and FAA policies to utilize ADR to the maximum extent practicable. Under the procedures presented in this part, the ODRA encourages parties to consider ADR techniques such as case evaluation, mediation, or arbitration. B. ADR encompasses a number of processes and techniques for resolving protests or contract disputes. The most commonly used types include: (1) Mediation. The neutral or compensated neutral ascertains the needs and interests of both parties and facilitates discussions between or among the parties and an amicable resolution of their differences, seeking approaches to bridge the gaps between the parties’’ respective positions. The neutral or compensated neutral can meet with the parties separately, conduct joint meetings with the parties’’ representatives, or employ both methods in appropriate cases. (2) Neutral Evaluation. At any stage during the ADR process, as the parties may agree, the neutral or compensated neutral will provide a candid assessment and opinion of the strengths and weaknesses of the parties’’ positions as to the facts and law, so as to facilitate further discussion and resolution. (3) Binding Arbitration. The ODRA, after consultation with the United States Department of Justice in accordance with the provisions of the Administrative Disputes Resolution Act offers true binding arbitration in cases within its jurisdiction.

Background On October 14, 2010, Embraer S.A. applied for a design change to Type Certificate No. A60CE for installation of a side-facing belted lavatory in the EMB–505 airplane. The belted lavatory will be used as a passenger seat during takeoff and landing; therefore, comply with the provisions of §§ 23.562 and 23.785 (in addition to the certification basis as established in type certificate A60CE) and any additional requirements the FAA determines are applicable. In this case, the approval of a side-facing seat to these provisions is considered new and novel and as such will require special conditions and specific methods of compliance to certificate. 14 CFR part 23 was amended August 8, 1988, by Amendment 23–36, to revise the emergency landing conditions that must be considered in the design of the airplane. Amendment 23–36 revised the static load conditions in § 23.561, and added a new § 23.562 that required dynamic testing for all seats approved VerDate Mar<15>2010 16:02 Sep 06, 2011 Jkt 223001 for occupancy during takeoff and landing. The intent of Amendment 23– 36 is to provide an improved level of safety for occupants on part 23 airplanes. Because most seating is forward-facing in part 23 airplanes, the pass/fail criteria developed in Amendment 23–36 focused primarily on these seats. Since the regulations do not address side-facing seats, these criteria should be documented in special conditions. The FAA decision to review compliance with these regulations stems from the fact that the current regulations do not provide adequate and appropriate standards for the type certification of this type of seat. These requirements are substantially similar to other single-place side-facing seat installations approved for use on several different part 25 aircraft. Type Certification Basis Under the provisions of § 21.101, Embraer S.A. must show that the model EMB 505 meets the applicable provisions of the regulations incorporated by reference in Type Certificate No. A60CE or the applicable regulations in effect on the date of application for the change to the Embraer model 505 type certificate. The regulations incorporated by reference in the type certificate are commonly referred to as the ‘‘original type certification basis.’’ The following model is covered by this special condition: Embraer S.A. EMB 505: For the model listed above, the certification basis also includes all exemptions, if any; equivalent level of safety findings, if any; and special conditions not relevant to the special conditions adopted by this rulemaking action. If the Administrator determines that the applicable airworthiness regulations (i.e., part 23 as amended) do not contain adequate or appropriate safety standards for the Embraer S.A. model EMB 505 with a side-facing seat as installed on this Embraer S.A. Aircraft model because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. The FAA issues special conditions, as appropriate, as defined in § 11.19, in accordance with § 11.38, and become part of the type certification basis in accordance with § 21.101. Novel or Unusual Design Features The Embraer S.A., model EMB 505, will incorporate the following novel or unusual design feature: PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 55231 A side-facing lavatory seat intended for taxi/takeoff and landing. Discussion The seat is to incorporate design features that reduce the potential for injury in the event of an accident. In a severe impact, the occupant will be restrained by a 2-point seatbelt and bear on an adjacent padded wall. In addition to the design features intended to minimize occupant injury during an accident sequence, the installation will also require operational procedures that will facilitate egress after an accident, including leaving the lavatory door locked open during taxi, takeoff and landing. The adjacent forward wall/ bulkhead interior structure will have padding, which will provide some protection to the head of the occupant. The Code of Federal Regulations states performance criteria for forwardand aft-facing seats and restraints in an objective manner. However, none of these criteria are adequate to address the specific issues raised concerning sidefacing seats. Therefore, the FAA has determined that, in addition to the requirements of parts and 23, special conditions are needed to address the installation of this seat installation/ restraint. Accordingly, these special conditions are for the Embraer S.A., model EMB 505, side-facing seat location. Other conditions may be developed, as needed, based on further FAA review and discussions with the manufacturer and civil aviation authorities. Applicability As discussed above, these special conditions are applicable to the EMB 505. Should Embraer S.A. apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature, the special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features on one model of airplane. It is not a rule of general applicability, and it affects only the applicant who applied to the FAA for approval of these features on the airplane. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, because a delay would significantly affect the E:\FR\FM\07SER1.SGM 07SER1 55232 Federal Register / Vol. 76, No. 173 / Wednesday, September 7, 2011 / Rules and Regulations certification of the airplane, which is imminent, the FAA has determined that prior public notice and comment are unnecessary and impracticable, and good cause exists for adopting these special conditions upon issuance. The FAA is requesting comments to allow interested persons to submit views that may not have been submitted in response to the prior opportunities for comment described above.

Citation The authority citation for these special conditions is as follows: jlentini on DSK4TPTVN1PROD with RULES Authority: 49 U.S.C. 106(g), 40113 and 44701; 14 CFR 21.16 and 21.101; and 14 CFR 11.38 and 11.19. The Special Conditions The minimum acceptable standards for dynamic seat certification of the belted lavatory seat are as follows: (a) Existing Criteria. As referenced by § 23.785(b), all injury protection criteria of §§ 23.562(c)(1) through (c)(7) apply to the occupants of the side-facing seats. Head injury criteria (HIC) assessments are only required for head contact with the seat and/or adjacent structures. (b) Body-to-wall/furnishing contact. The seat must be installed aft of a structure such as an interior wall or furnishing that will contact the pelvis, upper arm, chest, or head of an occupant seated next to the structure. A conservative representation of the structure and its stiffness must be included in the tests. It is required that the contact surface of this structure must be covered with at least two inches of energy absorbing protective padding (foam or equivalent), such as Ensolite. (c) Thoracic Trauma. Testing with a Side Impact Dummy (SID), as defined by 49 CFR part 572, Subpart F, or its equivalent, must be performed in order to establish Thoracic Trauma Index (TTI) injury criteria. TTI acquired with the SID must be less than 85, as defined in 49 CFR part 572, Subpart F. SID TTI data must be processed as defined in Federal Motor Vehicle Safety Standard (FMVSS) Part 571.214, section S6.13.5. Rational analysis, comparing an installation with another installation where TTI data were acquired and found acceptable, may also be viable. (d) Pelvis. Pelvic lateral acceleration must not exceed 130g. Pelvic acceleration data must be processed as defined in FMVSS Part 571.214, section S6.13.5. (e) Shoulder Strap Loads. Where upper torso straps (shoulder straps) are VerDate Mar<15>2010 16:02 Sep 06, 2011 Jkt 223001 used for occupants, tension loads in individual straps must not exceed 1,750 pounds. If dual straps are used for restraining the upper torso, the total strap tension loads must not exceed 2,000 pounds. (f) Compression Loads. The compression load measured between the pelvis and the lumbar spine of the ATD may not exceed 1,500 pounds. (g) Emergency Evacuation. When occupied, the lavatory door must be latched open for takeoff and landing and must remain latched under the § 23.561(b) loads. The airplane configuration must meet the emergency evaluation requirements of its certification basis with the seat occupied. (h) Lavatory Door Placard. A placard specifying the lavatory door must be latched open for takeoff and landing when occupied must be displayed on the outside of the door. (i) Test Requirements in § 23.562 dynamic loads. The tests in § 23.562(a), (b) and (c) must be conducted on the lavatory seat. Floor deformation is required except for a seat that is cantilevered to the bulkhead. The following are the agreed to methods of compliance and testing requirements: DEPARTMENT OF TRANSPORTATION General Test Guidelines FOR FURTHER INFORMATION CONTACT: (a) One longitudinal test with the SID ATD or its equivalent, undeformed floor, no yaw, and with all lateral structural supports (armrests/walls) will be accomplished. —Pass/fail injury assessments: TTI and pelvic acceleration. (b) One longitudinal test with the Hybrid II ATD, deformed floor, with 10 degrees yaw, and with all lateral structural supports (armrests/walls) will be accomplished. —Pass/fail injury assessments: HIC and upper torso restraint load, restraint system retention and pelvic acceleration. (c) Vertical (15 G’s) test is to be conducted with modified Hybrid II ATDs with existing pass/fail criteria. (d) The ATD can be tethered for the floor deformation test. (e) The seatbelt is not required to have a TSO Authorization but will need to comply with the TSO–C22g Minimum Performance Standards (MPS). Issued in Kansas City, Missouri, on August 31, 2011.

Background

    On October 14, 2010, Embraer S.A. applied for a design change to 
Type Certificate No. A60CE for installation of a side-facing belted 
lavatory in the EMB-505 airplane. The belted lavatory will be used as a 
passenger seat during takeoff and landing; therefore, comply with the 
provisions of Sec. Sec.  23.562 and 23.785 (in addition to the 
certification basis as established in type certificate A60CE) and any 
additional requirements the FAA determines are applicable. In this 
case, the approval of a side-facing seat to these provisions is 
considered new and novel and as such will require special conditions 
and specific methods of compliance to certificate.
    14 CFR part 23 was amended August 8, 1988, by Amendment 23-36, to 
revise the emergency landing conditions that must be considered in the 
design of the airplane. Amendment 23-36 revised the static load 
conditions in Sec.  23.561, and added a new Sec.  23.562 that required 
dynamic testing for all seats approved for occupancy during takeoff and 
landing. The intent of Amendment 23-36 is to provide an improved level 
of safety for occupants on part 23 airplanes. Because most seating is 
forward-facing in part 23 airplanes, the pass/fail criteria developed 
in Amendment 23-36 focused primarily on these seats. Since the 
regulations do not address side-facing seats, these criteria should be 
documented in special conditions.
    The FAA decision to review compliance with these regulations stems 
from the fact that the current regulations do not provide adequate and 
appropriate standards for the type certification of this type of seat.
    These requirements are substantially similar to other single-place 
side-facing seat installations approved for use on several different 
part 25 aircraft.

Type Certification Basis

    Under the provisions of Sec.  21.101, Embraer S.A. must show that 
the model EMB 505 meets the applicable provisions of the regulations 
incorporated by reference in Type Certificate No. A60CE or the 
applicable regulations in effect on the date of application for the 
change to the Embraer model 505 type certificate. The regulations 
incorporated by reference in the type certificate are commonly referred 
to as the ``original type certification basis.''
    The following model is covered by this special condition:
    Embraer S.A. EMB 505:
    For the model listed above, the certification basis also includes 
all exemptions, if any; equivalent level of safety findings, if any; 
and special conditions not relevant to the special conditions adopted 
by this rulemaking action.
    If the Administrator determines that the applicable airworthiness 
regulations (i.e., part 23 as amended) do not contain adequate or 
appropriate safety standards for the Embraer S.A. model EMB 505 with a 
side-facing seat as installed on this Embraer S.A. Aircraft model 
because of a novel or unusual design feature, special conditions are 
prescribed under the provisions of Sec.  21.16.
    The FAA issues special conditions, as appropriate, as defined in 
Sec.  11.19, in accordance with Sec.  11.38, and become part of the 
type certification basis in accordance with Sec.  21.101.

Novel or Unusual Design Features

    The Embraer S.A., model EMB 505, will incorporate the following 
novel or unusual design feature:
    A side-facing lavatory seat intended for taxi/takeoff and landing.

Discussion

    The seat is to incorporate design features that reduce the 
potential for injury in the event of an accident. In a severe impact, 
the occupant will be restrained by a 2-point seatbelt and bear on an 
adjacent padded wall. In addition to the design features intended to 
minimize occupant injury during an accident sequence, the installation 
will also require operational procedures that will facilitate egress 
after an accident, including leaving the lavatory door locked open 
during taxi, takeoff and landing. The adjacent forward wall/bulkhead 
interior structure will have padding, which will provide some 
protection to the head of the occupant.
    The Code of Federal Regulations states performance criteria for 
forward- and aft-facing seats and restraints in an objective manner. 
However, none of these criteria are adequate to address the specific 
issues raised concerning side-facing seats. Therefore, the FAA has 
determined that, in addition to the requirements of parts and 23, 
special conditions are needed to address the installation of this seat 
installation/restraint.
    Accordingly, these special conditions are for the Embraer S.A., 
model EMB 505, side-facing seat location. Other conditions may be 
developed, as needed, based on further FAA review and discussions with 
the manufacturer and civil aviation authorities.

Applicability

    As discussed above, these special conditions are applicable to the 
EMB 505. Should Embraer S.A. apply at a later date for a change to the 
type certificate to include another model incorporating the same novel 
or unusual design feature, the special conditions would apply to that 
model as well.

Conclusion

    This action affects only certain novel or unusual design features 
on one model of airplane. It is not a rule of general applicability, 
and it affects only the applicant who applied to the FAA for approval 
of these features on the airplane.
    The substance of these special conditions has been subjected to the 
notice and comment period in several prior instances and has been 
derived without substantive change from those previously issued. It is 
unlikely that prior public comment would result in a significant change 
from the substance contained herein. Therefore, because a delay would 
significantly affect the

[[Page 55232]]

certification of the airplane, which is imminent, the FAA has 
determined that prior public notice and comment are unnecessary and 
impracticable, and good cause exists for adopting these special 
conditions upon issuance. The FAA is requesting comments to allow 
interested persons to submit views that may not have been submitted in 
response to the prior opportunities for comment described above.

adjacent structures.
    (b) Body-to-wall/furnishing contact. The seat must be installed aft 
of a structure such as an interior wall or furnishing that will contact 
the pelvis, upper arm, chest, or head of an occupant seated next to the 
structure. A conservative representation of the structure and its 
stiffness must be included in the tests. It is required that the 
contact surface of this structure must be covered with at least two 
inches of energy absorbing protective padding (foam or equivalent), 
such as Ensolite.
    (c) Thoracic Trauma. Testing with a Side Impact Dummy (SID), as 
defined by 49 CFR part 572, Subpart F, or its equivalent, must be 
performed in order to establish Thoracic Trauma Index (TTI) injury 
criteria. TTI acquired with the SID must be less than 85, as defined in 
49 CFR part 572, Subpart F. SID TTI data must be processed as defined 
in Federal Motor Vehicle Safety Standard (FMVSS) Part 571.214, section 
S6.13.5. Rational analysis, comparing an installation with another 
installation where TTI data were acquired and found acceptable, may 
also be viable.
    (d) Pelvis. Pelvic lateral acceleration must not exceed 130g. 
Pelvic acceleration data must be processed as defined in FMVSS Part 
571.214, section S6.13.5.
    (e) Shoulder Strap Loads. Where upper torso straps (shoulder 
straps) are used for occupants, tension loads in individual straps must 
not exceed 1,750 pounds. If dual straps are used for restraining the 
upper torso, the total strap tension loads must not exceed 2,000 
pounds.
    (f) Compression Loads. The compression load measured between the 
pelvis and the lumbar spine of the ATD may not exceed 1,500 pounds.
    (g) Emergency Evacuation. When occupied, the lavatory door must be 
latched open for takeoff and landing and must remain latched under the 
Sec.  23.561(b) loads. The airplane configuration must meet the 
emergency evaluation requirements of its certification basis with the 
seat occupied.
    (h) Lavatory Door Placard. A placard specifying the lavatory door 
must be latched open for takeoff and landing when occupied must be 
displayed on the outside of the door.
    (i) Test Requirements in Sec.  23.562 dynamic loads. The tests in 
Sec.  23.562(a), (b) and (c) must be conducted on the lavatory seat. 
Floor deformation is required except for a seat that is cantilevered to 
the bulkhead.
    The following are the agreed to methods of compliance and testing 
requirements:

General Test Guidelines

    (a) One longitudinal test with the SID ATD or its equivalent, 
undeformed floor, no yaw, and with all lateral structural supports 
(armrests/walls) will be accomplished.

--Pass/fail injury assessments: TTI and pelvic acceleration.

    (b) One longitudinal test with the Hybrid II ATD, deformed floor, 
with 10 degrees yaw, and with all lateral structural supports 
(armrests/walls) will be accomplished.

--Pass/fail injury assessments: HIC and upper torso restraint load, 
restraint system retention and pelvic acceleration.

    (c) Vertical (15 G's) test is to be conducted with modified Hybrid 
II ATDs with existing pass/fail criteria.
    (d) The ATD can be tethered for the floor deformation test.
    (e) The seatbelt is not required to have a TSO Authorization but 
will need to comply with the TSO-C22g Minimum Performance Standards 
(MPS).
