## Summary

We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC 155B, EC155B1, SA-365N, SA- 365N1, AS-365N2, AS 365 N3, and SA-366G1 helicopters. This proposed AD would require inspecting the collective pitch lever for correct locking and unlocking conditions. This proposed AD is prompted by two separate reports of inadvertent collective pitch lever locking and unlocking. The proposed actions are intended to detect an incorrectly adjusted collective pitch lever, which could result in loss of control of the helicopter.
