Summary
This document revises an earlier proposed airworthiness directive (AD) for Eurocopter France Model AS332C, L, and L1 helicopters. That proposed AD would have required inspecting the horizontal stabilizer spar tube (spar tube) for corrosion, hardness, cracks, and scratches, and if necessary, replacing any unairworthy spar tube and bushing with an airworthy spar tube and bushing. That proposal was prompted by the loss of a horizontal stabilizer in flight due to a spar tube failure. This action revises the proposed AD by correcting the model number given in the applicability section. The actions specified by this proposed AD are intended to prevent failure of the spar tube, separation of the horizontal stabilizer and impact with the main or tail rotor, and subsequent loss of control of the helicopter.
