Airbus Helicopters Helicopters
This AD applies to Airbus Helicopters AS355E, AS355F, AS355F1, AS355F2, AS355N.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This AD was prompted by reports of cracks in the legs of the side supports of the tail rotor transmission fan. This AD requires repetitively inspecting the side supports of the tail rotor transmission fan for cracks and, depending on the results, replacing both side supports. The FAA is issuing this AD to address the unsafe condition on these products.
