## Abstract

This amendment adopts a new airworthiness directive (AD) for the specified fire extinguishers. This action requires replacing each unairworthy portable fire extinguisher with an airworthy portable fire extinguisher. This amendment is prompted by an ongoing investigation that has established that unapproved Halon 1211 has been used to fill L'Hotellier portable fire extinguishers that are likely to be onboard various model helicopters. The actions specified in this AD are intended to prevent using contaminated gas that may reduce fire suppression and release toxic fumes that would endanger the safety of the helicopter and its occupants.
