Flightcrew Compartment Access and Door Designs

This action supersedes SFAR 92-1, which was published October 17, 2001, allowing air carriers to quickly modify the flightcrew compartment door to delay or deter unauthorized entry to the flightcrew compartment. This action temporarily authorizes variances from existing design standards for the doors and allows for approval for return to service of modified airplanes without prior approved data if the modification constitutes a major alteration. This action prohibits the possession of flightdeck compartment door keys by other than the flightcrew during flight, unless the flightdeck door has an internal flightdeck locking device installed, operative, and in use. This action also clarifies the 90 day and 180 day time frames in earlier versions of this SFAR with specific dates. This action is being taken in the wake of the September 11, 2001, terrorist attacks against four U.S. commercial airplanes.
