Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC 155B, EC155B1, SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters, as identified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD. This AD was prompted by a report of an in-flight loss of engine and main gearbox (MGB) cowlings. This AD requires inspecting the MGB fixed cowling front fitting (MGB front fitting), and depending on findings, corrective action. This AD also requires a new modification, which is a terminating action for the inspection, as specified in an EASA AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
