Discussion

    A common cause of airplane fires has been the ignition of leaked 
flammable fluids. The primary means of preventing these fires is to 
safely drain the fluid away from the airplane, both in flight and on 
the ground, and to provide ventilation that results in a lean fuel to 
air mixture. The purpose of this AC is to provide guidance in what 
factors should be considered in the design of flammable fluid drainage 
systems and ventilation systems, and to describe a means of showing 
compliance with the sections of the FAR that require these systems. 
This AC provides information and guidance concerning a means, but not 
the only means, of compliance with the portions of part 25 of the FAR 
pertaining to certification requirements for compartments in transport 
category airplanes that contain flammable fluid leakage sources.

    Issued in Renton, Washington, on July 14, 1995.
