Advisory Circular 27-1A, Certification of Normal Category Rotorcraft

Advisory Circular (AC) 27-1A, Certification of Normal Category Rotorcraft, is a total revision of AC 27-1 dated August 29, 1985, with changes 1, 2, 3, and 4 dated September 16, 1987, April 24, 1989, September 12, 1991, and August 18, 1995, respectively, incorporated. In addition, new material plus changes to existing paragraphs have been incorporated to bring the AC up-to-date with various rule changes to 14 CFR Part 27. As part of the FAA effort to achieve national standardization in rotorcraft certification, the AC serves as a ready reference for manufacturers, modifiers, FAA design evaluation engineers, flight test engineers, and engineering flight test pilots and has been harmonized with the Joint Aviation Authority (JAA) to establish common guidance for the U.S. and for JAA member nations. The AC material has no legally binding status and must be treated as advisory only.
