Abstract
We are adopting a new airworthiness directive (AD) for the Eurocopter France (ECF) Model SA-365C, SA-365C1, SA-365C2, SA-365N, SA- 365N1, AS-365N2, AS 365 N3, and SA-366G1 helicopters. This AD was prompted by some reports of deterioration and two reports of failure of Starflex star arm ends. The actions are intended to modify the main rotor frequency adapters to reduce the temperature in the area, to prevent failure of the star arm end, severe vibration, and subsequent loss of control of the helicopter.
