Discussion

    This proposed AC provides information and guidance on compliance 
with the airworthiness standards for transport category airplanes about 
limiting the time a fuel tank may be flammable or mitigation of hazards 
from flammable fuel air mixtures within fuel tanks. This guidance is 
applicable to transport category airplanes for which a new, amended, or 
supplemental type certificate is requested and affected existing design 
approval holders as stated in proposed Sec. Sec.  25.1815, 25.1817, 
25.1819, and 25.1821 contained in a proposed new subpart I to Title 14, 
Code of Federal Regulations (14 CFR) part 25, ``Continued Airworthiness 
and Safety Improvement.'' The AC also provides guidance on compliance 
with the associated proposed requirements for operators of affected 
airplanes that must comply with the requirements of 14 CFR parts 91, 
121, 125, and 129 (for a foreign person or foreign air carrier 
operating a U.S.-registered airplane) to incorporate flammability 
mitigation means by specified dates.
    The Notice of Proposed Rulemaking would not apply the proposed new 
requirements to transport category airplanes designed solely for cargo 
carriage. However, AC 25.981-2 remains applicable to these airplanes, 
which must comply with the current flammability standards contained in 
Sec.  25.981(c) that would be moved to the proposed section Sec.  
25.981(e). We will consider combining this guidance for all transport 
category airplanes into one AC when the final rule and AC are issued.
    It is one means, but not the only means, of complying with the part 
25 revisions proposed in Notice No. 05-14 entitled ``Fuel Tank 
Flammability Reduction,'' published in this same edition of the Federal 
Register. Issuance of AC 25.981-2A is contingent on final adoption of 
the proposed revisions to part 25.

    Issued in Renton, Washington, on November 16, 2005.

Service.
