ACTION: Request for comments. AGENCY: The Federal Aviation Administration (FAA) is requesting comments and information on the public’s interest in restructuring the rotorcraft airworthiness standards of normal category rotorcraft and transport category rotorcraft. Specifically, the agency is seeking comments on whether to change the existing applicability standards for maximum weight and number of passenger seats for either or both types of rotorcraft, or whether to consider other approaches for determining applicability. The FAA is soliciting public input because of some rotorcraft community interest in increasing the 7,000 pound maximum weight limit for the modern normal category rotorcraft and because there may be recommendations for new approaches to make the rotorcraft airworthiness standards more efficient and adaptable to future technology. This action is part of an effort to develop recommendations for possible FAA rulemaking action. DATES: Send your comments to reach us on or before May 23, 2013.

SUPPLEMENTARY INFORMATION: Your Comments Are Welcome We invite your comments on the issues described in this request. The most useful comments are those that address the questions identified in the Request for Comments section below. Responses to these questions will be helpful in evaluating the issues and determining what future actions we should undertake. To ensure consideration, you must submit comments as specified under the ADDRESSES section of this preamble. We will consider all communications received on or before the closing date for comments. All comments submitted will be available for examination, both before and after the closing date for comments, under the docket number FAA–2013–0144 at https:// www.regulations.gov. Background and Discussion Currently, the applicability rule for part 27 (14 CFR 27.1) prescribes airworthiness standards for ‘‘normal category rotorcraft with maximum weights of 7,000 pounds or less and nine or less passenger seats.’’ Rotorcraft with a maximum weight greater than 7,000 pounds or with 10 or more passenger seats are certificated as transport category rotorcraft under part 29. The applicability rules for rotorcraft certificated under parts 27 and 29 have been discussed since the early 1990s. In February 1994, the FAA held a public meeting to determine a course of action PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 that was in the best interest of the public and the aviation community. Subsequently, an Aviation Rulemaking Advisory Committee working group was established with representatives from the FAA, the Joint Aviation Authorities, and Transport Canada Civil Aviation, as well as from U.S. and European helicopter manufacturers. In February 1995, the Rotorcraft Gross Weight and Passenger Issues Working Group was established and tasked with recommending new or revised requirements for increasing the gross weight and passenger limitations for normal category rotorcraft. There was agreement to increase the gross weight limitation of part 27 from 6,000 to 7,000 pounds with added passenger safety requirements. More recently we have recognized that the evolution of the part 27 and 29 rules has not kept pace with technology and the capability of newer rotorcraft. Therefore, the FAA is interested in investigating new approaches to make the rotorcraft airworthiness regulations more efficient and adaptable to future technology. Additionally, the FAA has found that without a rulemaking effort to extensively revise the rotorcraft standards, we are left with the option of issuing multiple special conditions for the same technologies (fly-by-wire flight control systems, search and rescue approach, etc.). If we find adequate interest from the rotorcraft community, we would consider initiating a rulemaking effort, similar in scope to the proposed revisions of the small airplane part 23 standards. The new part 23 rulemaking initiative resulted from a determination that applying a weight standard to certification for small aircraft was no longer relevant. Conversely, if the level of interest indicates the current standards remain appropriate but would benefit from some revision, we may undertake a smaller rulemaking effort to update a limited number of regulations in parts 27 and 29. Request for Comments As noted above, the FAA is seeking comments to determine whether an all new approach for parts 27 and 29 is appropriate for future rotorcraft airworthiness standards and safety levels, or whether the existing standards philosophy based on weight (currently 7,000 pound maximum for part 27) and maximum number of passengers (currently maximum of 9 passengers for part 27) is appropriate. In providing your comments, we would find it most useful if you address some or all of the following questions: E:\FR\FM\22FEP1.SGM 22FEP1 Federal Register / Vol. 78, No. 36 / Friday, February 22, 2013 / Proposed Rules (a) To what extent do you believe the current rotorcraft certification standards need to be amended to remain relevant over the next 20 years, given the rapid pace of advances in technology? (b) Should the current rotorcraft certification standards be completely changed, or are weight and number of passengers still relevant for determining certification? (c) If you believe certification should continue to be based on weight and number of passengers, to what extent should the existing standards be updated, and how? (d) As revisions to regulatory certification standards would require participation in a rulemaking committee over a substantial period of time, to what extent would you be willing to participate? As a convenience, these questions are available for submission in the same format as above at the following Web site link: https://www.faa.gov/aircraft/ air_cert/design_approvals/rotorcraft/ comm. If the FAA decides to have further rulemaking discussions on these issues, we will issue a document, giving the public another opportunity to comment. Issued in Fort Worth, TX, on February 8, 2013.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0243 (Correction: November 13, 2012), dated November 12, 2012, a Mandatory Continuing Airworthiness Information (referred to hereinafter as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: A review, carried out by Rolls-Royce, of the lives of critical parts of the Viper Mk. 601– 22 engine, has resulted in reduced cyclic life limits for certain critical parts. Operation of critical parts beyond these reduced cyclic life limits may result in part failure, possibly resulting in the release of high-energy debris, which may cause damage to the aeroplane and/or injury to the occupants. For the reasons described above, this AD requires implementation of the reduced cyclic life limits for the affected critical parts, i.e., replacement of each part before the applicable reduced life limit is exceeded, and replacement of those critical parts that have already exceeded the reduced cyclic life limits. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information RR Alert Service Bulletin 72–A206, dated November, 2012. FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of the United Kingdom and is approved for operation in the United States.

Background and Discussion

    Currently, the applicability rule for part 27 (14 CFR 27.1) 
prescribes airworthiness standards for ``normal category rotorcraft 
with maximum weights of 7,000 pounds or less and nine or less passenger 
seats.'' Rotorcraft with a maximum weight greater than 7,000 pounds or 
with 10 or more passenger seats are certificated as transport category 
rotorcraft under part 29.
    The applicability rules for rotorcraft certificated under parts 27 
and 29 have been discussed since the early 1990s. In February 1994, the 
FAA held a public meeting to determine a course of action that was in 
the best interest of the public and the aviation community. 
Subsequently, an Aviation Rulemaking Advisory Committee working group 
was established with representatives from the FAA, the Joint Aviation 
Authorities, and Transport Canada Civil Aviation, as well as from U.S. 
and European helicopter manufacturers. In February 1995, the Rotorcraft 
Gross Weight and Passenger Issues Working Group was established and 
tasked with recommending new or revised requirements for increasing the 
gross weight and passenger limitations for normal category rotorcraft. 
There was agreement to increase the gross weight limitation of part 27 
from 6,000 to 7,000 pounds with added passenger safety requirements.
    More recently we have recognized that the evolution of the part 27 
and 29 rules has not kept pace with technology and the capability of 
newer rotorcraft. Therefore, the FAA is interested in investigating new 
approaches to make the rotorcraft airworthiness regulations more 
efficient and adaptable to future technology. Additionally, the FAA has 
found that without a rulemaking effort to extensively revise the 
rotorcraft standards, we are left with the option of issuing multiple 
special conditions for the same technologies (fly-by-wire flight 
control systems, search and rescue approach, etc.).
    If we find adequate interest from the rotorcraft community, we 
would consider initiating a rulemaking effort, similar in scope to the 
proposed revisions of the small airplane part 23 standards. The new 
part 23 rulemaking initiative resulted from a determination that 
applying a weight standard to certification for small aircraft was no 
longer relevant. Conversely, if the level of interest indicates the 
current standards remain appropriate but would benefit from some 
revision, we may undertake a smaller rulemaking effort to update a 
limited number of regulations in parts 27 and 29.

Request for Comments

    As noted above, the FAA is seeking comments to determine whether an 
all new approach for parts 27 and 29 is appropriate for future 
rotorcraft airworthiness standards and safety levels, or whether the 
existing standards philosophy based on weight (currently 7,000 pound 
maximum for part 27) and maximum number of passengers (currently 
maximum of 9 passengers for part 27) is appropriate. In providing your 
comments, we would find it most useful if you address some or all of 
the following questions:

[[Page 12255]]

    (a) To what extent do you believe the current rotorcraft 
certification standards need to be amended to remain relevant over the 
next 20 years, given the rapid pace of advances in technology?
    (b) Should the current rotorcraft certification standards be 
completely changed, or are weight and number of passengers still 
relevant for determining certification?
    (c) If you believe certification should continue to be based on 
weight and number of passengers, to what extent should the existing 
standards be updated, and how?

the same format as above at the following Web site link: https://www.faa.gov/aircraft/air_cert/design_approvals/rotorcraft/comm.
    If the FAA decides to have further rulemaking discussions on these 
issues, we will issue a document, giving the public another opportunity 
to comment.
