Summary
We propose to supersede airworthiness directive (AD) 2013-18- 01 for Eurocopter France Model EC 155B, EC155B1, SA-365N, SA-365N1, AS- 365N2, AS-365-N3, and SA-366G1 helicopters. AD 2013-18-01 currently requires inspecting the collective pitch lever for correct locking and unlocking conditions. As published, AD 2013-18-01 contains certain errors. This proposed AD would retain the requirements of AD 2013-18- 01, correct these errors, and update the type certificate holder's name. The proposed actions are intended to detect an incorrectly adjusted collective pitch lever, which could result in loss of control of the helicopter.
