Summary

We propose to supersede airworthiness directive (AD) 2015-22- 02 for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. AD 2015-22-02 requires inspecting the tail rotor (TR) pitch link assemblies. This proposed AD would retain the inspections of AD 2015-22-02 and would require replacing certain pitch link bearings. Since we issued AD 2015-22-02, Bell has introduced a new design bearing. The actions of this proposed AD are intended to prevent an unsafe condition on these products.

The agency’s own summary, as published.
