Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. This proposed AD would require installing a cut-out for the left-hand (LH) and right-hand (RH) rail support junction profiles and inspecting splices, frame 5295, and related equipment for a crack. This proposed AD is prompted by reports of cracks on frame 5295 and on splices installed to prevent those cracks. The proposed actions are intended to detect a crack in frame 5295, which could lead to loss of the helicopter frame's structural integrity and consequently, loss of helicopter control.
