## Summary

We propose to adopt a new airworthiness directive (AD) for certain Eurocopter France (Eurocopter) Model AS350 and AS355 helicopters. This proposed AD would require inspecting the tail rotor control stop screws to determine if they are correctly aligned and adjusting the screws if they are misaligned. This proposed AD is prompted by the discovery of a loose nut on the tail rotor control stop and a misaligned tail rotor control stop screw. The proposed actions are intended detect a loose nut or a misaligned stop screw, which, if not corrected, could limit yaw authority, and consequently, result in a loss of helicopter control.
