Airworthiness Directives; Eurocopter France Model AS332L2 Helicopters

This amendment adopts a new airworthiness directive (AD) for Eurocopter France (ECF) Model AS332L2 helicopters. This action requires visually inspecting the engine compartment fire extinguisher bottle (bottle) for correct placement and installation of the percussion heads and attachment cartridges and if, incorrectly installed, making the necessary corrections. This action also requires marking the bottle's indicating label with "Amendment A" after making the necessary corrections. This amendment is prompted by the discovery that some of the spare bottles have interchanged percussion heads. The actions specified in this AD are intended to prevent release of the fire- extinguishing agent into the wrong engine compartment, failure to extinguish a fire, and subsequent loss of control of the helicopter.
