## Summary

This document proposes the adoption of a new airworthiness directive (AD) applicable to BHTC Model 222, 222B, 222U, and 230 helicopters. This proposal would require inspecting each flapping bearing to yoke attachment bolt (bolt) and replacing each bolt that shows thread damage, shank wear, or corrosion pitting with an airworthy bolt. This proposal is prompted by the discovery of a fractured bolt during a post-flight inspection. The actions specified by the proposed AD are intended to prevent a fracture of a bolt, failure of the bearing and yoke interface, and subsequent loss of control of the helicopter.
