AD FAA-2025-3999

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, and AS350D helicopters. This AD was prompted by a report of non- conformity of a certain cargo hook. This AD requires inspecting the gap between the filler and the side plates of the affected cargo hook and, depending on the results, replacing the cargo hook. This AD also prohibits installing an affected cargo hook on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
