Methods, Techniques & Practices AC

The FAA has released a proposed revision to Advisory Circular 43.13-2A, Acceptable Methods, Techniques, and Practices--Aircraft Alterations. This AC provides information to mechanics and repair stations on how to perform simple alterations to non-pressurized, certificated aircraft weighing less than 12,500 pounds. The AC was last updated in 1977.

The FAA plans to include a new policy that would allow mechanics and repair stations to use acceptable data as approved data for major alterations to certain non-pressurized aircraft. This new policy would be similar to the policy on acceptable data contained in AC 43.13-1B, Acceptable Methods, Techniques, and Practices--Aircraft Inspection and Repair.

The intent of the new policy would be to reduce the need for field approvals for alterations to certain non-pressurized aircraft without reducing the level of safety. Comments on the AC revision were due June 9, 2005.
