Summary
We propose to adopt a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model AS332C, AS332L, AS332L1, AS332L2, and SA330J helicopters. This proposed AD would require inspecting the crimping of the ball joint of the upper- and lower- end- fittings of the main servo-control and, depending on findings, replacing the main servo-control or repairing the ball joint. This proposed AD is prompted by incidents of missing crimping on the ball joints of servo-control end-fittings. The proposed actions are intended to prevent failure of a main servo-control upper end fitting, and subsequent failure of the flight controls and loss of control of the helicopter.
