Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model SA341G and SA342J helicopters. This action requires inspecting the tail gearbox support tripod (support tripod) for cracks. This amendment is prompted by reports of cracks that were discovered during routine maintenance inspections. The actions specified in this AD are intended to detect cracks at the welds of the tail gearbox support tripod, which could cause failure of one or more of the tripod arms, subsequent separation of the tail gearbox, and loss of control of the helicopter.
