Background 

The FAA developed this proposed 

revision to AC 20–42C with direct 

industry assistance through the 

International Aircraft Systems Fire 

Protection Working Group (IASFPWG). 

The proposed revision will provide 

users with updated guidance on 

available extinguishing agents. 

Specifically, the revised AC will 

provide guidance on the effectiveness 

and safe-use of Halon 1211 and three 

FAA approved replacement agents. 

It: (1) Establishes an FAA approved 

minimum performance standard (MPS) 

for halon replacement agents developed 

by the FAA Technical Center which 

requires a hidden fire test and a seat 

fire/toxicity test; (2) Recommends that 

users of halon extinguishers transition 

to using the new halocarbon clean 

replacement agents in fire extinguishers 

kept onboard airplanes and rotorcraft; 

and (3) Provides guidance on how to 

gain certification for halocarbon clean 

agent extinguishers intended to replace 

Halon 1211 hand-held extinguishers.
