Abstract
The FAA is superseding Airworthiness Directive (AD) 2021-11- 03, which applied to certain Airbus Helicopters Model EC 155B, EC155B1, SA-365N, SA-365N1, AS-365N2, and AS 365 N3 helicopters. AD 2021-11-03 required inspecting the main gearbox (MGB) fixed cowling front fitting (MGB front fitting), and depending on findings, corrective action. This AD retains the requirements of AD 2021-11-03, and includes service information that was omitted for Airbus Helicopter Model EC 155B and EC155B1 helicopters, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
