## Summary

This document proposes adopting a new airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (Bell) helicopters. The AD would require a one-time inspection of the adjustable stop screws of the magnetic brake assembly; repairing, as appropriate, certain mechanical damage to the cyclic and collective flight control magnetic brake arm assembly (arm assembly), if necessary; and installing the stop screw with the proper adhesive, adjusting the arm assembly travel and applying slippage marks. This proposal is prompted by reports that the magnetic brake adjustable screws have backed out, which limited travel of the arm assembly. The actions specified by the proposed AD are intended to detect loose adjustable stop screws, that could result in limiting the travel of the cyclic and collective arm assembly, and subsequent loss of control of the helicopter.
