Discussion

    This proposed AC provides guidance for demonstrating compliance 
with the transport category airplane certification requirements of 
Sec.  25.863 Flammable fluid fire protection (as applicable to 
electrical system components) and Sec.  25.869 Fire protection: 
systems. The guidance provided in this proposed AC is directed to 
airplane manufacturers, modifiers, foreign regulatory authorities, FAA 
transport airplane type certification engineers, and designees. It is 
one means, but not the only means, of complying with the part 25 
revisions proposed in Notice No. 05-08, entitled ``Enhanced 
Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS/
FTS),'' published in this same edition of the Federal Register. 
Issuance of AC 25.869-1 is contingent on final adoption of the proposed 
revisions to part 25.

    Issued in Washington, DC, on September 22, 2005.
John J. Hickey,
Director, Aircraft Certification Service.
