A new Federal Aviation Administration airworthiness directive (AD) involves a group of fire extinguishers used in various transport aircraft, helicopters and small airplanes. The extinguishers, built by Fire Fighting Enterprises, contain “significant quantities” of Halon 1211 gas, according to a UK Civil Aviation Authority report. The AD, which takes effect on Jan. 20, follows an EASA mandatory continuing airworthiness information (MCAI) alert issued to address the problem.
The ASTM D26.09 subcommittee will meet on January 27 in San Antonio from 1:00 pm to 4:00 pm, (although they may start earlier if other D26 subcommittees finish their business earlier in the morning). A prime agenda topic will be the contaminated halon found in the European aviation industry. The objective will be to see if they can fix the halon 1301 ASTM Standard so as to avoid future contamination going undetected at the recycling stage, and to form a working group to write a similar halon 1211 ASTM Standard. You do not need to be an ASTM member to attend the meeting (although they would like people to join).
