Airworthiness Directives; Eurocopter France Model SA330F, SA330G, SA330J, AS332C, AS332L, and AS332L1 Helicopters

摘要

This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters that requires inspecting each tail rotor blade de-icing rotating collector (collector) for radial play and rotation torque at specified intervals. If the play or torque exceeds the specified standard, this AD requires replacing the collector with an airworthy part. This amendment is prompted by excessive play measured on the collector of an ECF Model AS332 helicopter. The actions specified by this AD are intended to prevent wear of a collector bearing, loss of tail rotor effectiveness, and subsequent loss of control of the helicopter.
