FAA document on design standards for passenger aircraft / Transport Standards Branch
The FAA has compiled each of the 14CFR Part 25/Part 26 Rules and related guidance documents such as Advisory Circulars (ACs) and Policy Statements in the [Transport Standards Branch]. This section contains not only existing and newly issued materials, but also information on obsolete materials, and provides information on the background of the past.
The information is useful not only for developers of large aircraft, but also for developers of equipment that is expected to be installed on such aircraft. The FAA’s Transport Standards Branch is also a useful source of information for developers of other types of aircraft.
