The FAA has issued a request for comments on a final rule for an Airworthiness Directive (AD) for SICLI Halon 1211 portable fire extinguishers installed on various models of airplanes and rotorcraft, including some models built by Bombardier, Cessna, Dassault, Embraer and Eurocopter. According to the AD, the Civil Aviation Authority of the UK has informed the European Aviation Safety Agency that significant quantities of Halon 1211 gas, determined to be outside the required specification, have been supplied to the aviation industry for use in fire-extinguishing equipment. “This Halon 1211 subsequently has been used to fill P/N 1708337B4 portable fire extinguishers that are now likely to be installed in or carried on board aircraft. The contaminated nature of this gas, when used against a fire, may provide reduced fire suppression, endangering the safety of the aircraft and its occupants,” the AD states, while also noting,  “Extinguisher activation may lead to release of toxic fumes possibly causing injury to aircraft occupants.” The AD becomes effective March 8. The comment period ends on April 5.
