What this AD requires
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.
Which aircraft AD 2010-09-01 applies to
Applies only to helicopters with a Goodrich Electric hoist, P/N 76370-XXX, installed, that has not been modified per Modification (MOD) 073318 and that has a hoist motor other than an AUXILEC hoist motor.
Whether AD 2010-09-01 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
