TITLE: Interior Parts and Components Fire Protection for Transport Category Airplanes  
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT)  
ACTION: Notice of proposed rulemaking (NPRM); extension of comment period  
SUMMARY: This action extends the comment period for an NPRM that was published in  the Federal 
Register on 3 July 2019. In the NPRM, the FAA proposed to amend certain airworthiness regulations 
for fire protection of interior compartments on transport category airplanes. The proposal would 
convert those flammability regulations from deta iled, prescriptive requirements into simpler, 
performance -based standards. The proposal would divide these standards into two categories: those 
designed to protect the airplane and its occupants from the hazards of in -flight fires, and those 
designed to pr otect the airplane and its occupants from the hazards caused by post -crash fires. In 
addition, the proposal would remove test methods from the regulations and allow applicants, in 
certain cases, to demonstrate compliance either without conducting tests or by providing 
independent substantiation of the flammability characteristics of a proposed material. The proposal 
includes conforming changes to various FAA regulations. The proposal is necessary to eliminate 
unnecessary testing, increase standardization, a nd improve safety. The FAA is extending the closing 
date of the comment period to allow commenters time to adequately analyze the proposal and 
prepare responses.  
DATES: The comment period for the NPRM published on 3 July 2019 (84 FR 31747), and scheduled 
to close on 1 October 2019, is extended until 2 December 2019.
