AD FAA-2026-4638

Airworthiness Directives; Airbus Helicopters

Resumen

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, EC130B4, and EC130T2 helicopters. This AD was prompted by reports of an incorrectly installed engine flange on the main gear box (MGB) engine coupling. This AD requires inspecting the MGB engine coupling for correct installation and, depending on the results, corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
