## Abstract

We are adopting a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The MCAI AD was issued following the discovery of a potential risk of an untimely squib firing that would cut the hoist cable. A short circuit in the hoist motor brush power supply wiring resulting in an uncommanded squib firing, which cuts the hoist cable, constitutes an unsafe condition.
