Federal Aviation Administration (FAA), DOT.


Notice of proposed revision to advisory circular; extension of comment period.


On January 2, 2003, the FAA published a request for public comment on a proposed revision to Advisory Circular (AC) 25.562-1A, Dynamic Evaluation of Seat Restraint Systems and Occupant Protection on Transport Airplanes. The revised AC provides guidance on an improved procedure for selection of test articles, as well as criteria for determining whether analysis or testing is appropriate for substantiation. The comment period closes April 2, 2003; however, the FAA is extending the comment period to allow additional time to review the draft AC and develop comments in response to the notice.


Comments must be received on or before May 2, 2003.


You should send your comments on the proposed revision to the Federal Aviation Administration, Attention: Jeff Gardlin, Airframe/Cabin Safety Branch, ANM-115, Transport Airplane Directorate, Aircraft Certification Service, 1601 Lind Avenue SW., Renton, WA 98055-4056. You may also submit comments electronically to:
