STC Enables Halon-free Fire Extinguishers for Falcon 7X
Halotron BrX is weight efficient and leaves no residue after application

QCM Design has gained approval for Halotron BrX fire extinguishers that replace Halon-based extinguishers no longer allowed in EU-registered aircraft after 2025.

Switzerland-based QCM Design has developed an EASA supplemental type certificate (STC) to replace Halon fire extinguishers in Dassault’s Falcon 7X. The change helps Falcon 7X operators meet EASA’s Regulation No 1005/2009, “which stipulates that the use of portable extinguishers which contain Halon on aircraft is no longer permitted after 2025,” according to the company.

The new extinguishers installed under the STC use European Union- and EASA-approved Halotron BrX fire-extinguishing agent, made by American Pacific of Cedar City, Utah. BrX is more suited to aviation applications because it has a “lower weight equivalence to Halon 1211,” according to American Pacific, due to its chain-breaking effect.
