Abstract
This amendment adopts a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model SA-360C, SA-365C, SA-365C1, and SA-365C2 helicopters. This action requires inspecting the main gearbox (MGB) base plate for a crack and replacing the MGB if a crack is found. This amendment is prompted by the discovery of a crack in a MGB base plate. The actions specified in this AD are intended to detect a crack in a MGB base plate and prevent failure of one of the MGB attachment points to the frame, which could result in severe vibration and subsequent loss of control of the helicopter.
