Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters

概要

We propose to adopt a new airworthiness directive (AD) for Eurocopter Model SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. This proposed AD would require repetitively inspecting frame number (No.) 9 for a crack. This proposed AD is prompted by a report of a crack in frame No. 9 on an AS365 helicopter. The proposed actions are intended to detect a crack and prevent loss of structural integrity and subsequent loss of control of the helicopter.
