Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA 330F, G, and J helicopters. This proposal would require visually inspecting the intermediate gearbox (IGB) fairing safety stop (safety stop) for cracks, crazing, or edge wear, and if cracks, crazing, or edge wear exceeds the established limits, replacing the safety stop; and, inspecting to ensure that the inclined drive shaft fairing hinge pin is properly locked. A terminating action is provided in the AD by installing an additional safety stop on the IGB fairing. This proposal is prompted by one report of an accident involving the loss of the inclined drive shaft fairing. The actions specified by the proposed AD are intended to prevent loss of the inclined drive shaft fairing and impact with the tail rotor, and subsequent loss of control of the helicopter.
