Action
Final rule.
Summary
This action supersedes SFAR 92-2, which was published on November 21, 2001 to allow operators 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 also mandates these modifications on aircraft in certain passenger and cargo carrying operations and extends the January 15, 2002, reporting date. 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 is being taken in the wake of the September 11, 2001, terrorist attacks against four U.S. commercial airplanes.
