The European Aviation Safety Agency proposed a phase-out schedule for the use of halon in fire extinguishers in the cabins and lavatories of future Part 25 business aircraft and airliners, as well as Part 29 rotorcraft. It claims that there are currently or soon will be two non-halon alternative fire-extinguishing agents available for these compartments.
However, for APU and engine compartments, the agency is taking a “do nothing” position until weight and other technical issues for alternative fire-extinguisher agents are solved. The objective of the proposal is to “progressively mitigate the environmental impact that halon has on the atmosphere and climate change,” EASA said.
The proposed schedule calls for the replacement of halon in lavatories on newly produced aircraft starting on Jan. 1, 2016, and in handheld extinguishers on newly built aircraft starting Jan. 1, 2019. End dates for the use of halon on current and new type-certified aircraft are already in effect under EU regulations. A second proposal will address smaller airplanes and some rotorcraft used in international operations.
