Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 429 helicopters. This proposed AD would require inspecting each main rotor pitch link rod end bearing assembly (bearing) for wear and play. This proposed AD is prompted by reports of worn bearings. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
