Federal Aviation Administration (FAA), DOT.


Notice of proposed rulemaking (NPRM); extension of comment period.


This action extends the comment period for an NPRM that was published on April 21, 2006. In that document, the FAA proposed requirements for holders of design approvals to make available to operators damage tolerance data for repairs and alterations to fatigue critical structure. This extension is a result of requests from the Air Transport Association of America, Inc. (ATA), Airbus, Boeing Commercial Airplanes, Cargo Airline Association (CAA), and National Air Carrier Association, Inc. (NACA) to extend the comment period to the proposal.

On April 21, 2006, the Federal Aviation Administration (FAA) published Notice No. 05-11, Damage Tolerance Data for Repairs and Alterations (71 FR 20574). Comments to that document were to be received by July 20, 2006.

By letters dated May 26 and 30, and June 6, 9, and 12, the Air Transport Association of America, Inc. (ATA), Airbus, the Cargo Airline Association (CAA), Boeing Commercial Airplanes, and National Air Carrier Association, Inc. (NACA), respectively, asked the FAA to extend the comment period for Notice No. 05-11. Many of the petitioners said Notice No. 05-11, as well as other Aging Aircraft proposals and related guidance material, present complex issues that would take time to review together. Each petitioner requested a 60-day extension, except Boeing Commercial Airplanes, who requested a 90-day extension, to fully evaluate this proposal before sending comments to the FAA.

The FAA concurs with the petitioners' requests for an extension of the comment period on Notice No. 05-11. The FAA believes that a 90-day extension, as requested by Boeing Commercial Airplanes, would be excessive. As Notice No. 05-11 presents some complex issues, the FAA initially provided a 90-day comment period. Although the FAA agrees that additional time will allow industry to assess the impact of this regulation and provide meaningful comments, this need must be balanced against the need to proceed expeditiously with a rulemaking that will allow airline operators to comply with existing regulations.[1] We believe an additional 60 days, as requested by most of the petitioners, would be adequate for them to review and provide comment to Notice No. 05-11. Absent unusual circumstances, the FAA does not anticipate any further extension of the comment period for this rulemaking.

Extension of Comment Period

In accordance with § 11.47(c) of Title 14, Code of Federal Regulations, the FAA has reviewed the petitions made by ATA, Airbus, Boeing Commercial Airplanes, CAA, and NACA for extension of the comment period to Notice No. 05-11. These petitioners have shown a substantive interest in the proposed rule and good cause for the extension. The FAA also has determined that extension of the comment period is consistent with the public interest, and that good cause exists for taking this action.

Accordingly, the comment period for Notice No. 05-11 is extended until September 18, 2006.
