Action
Final rule; request for comments.
Summary
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Model SA341G and SA342J. This AD prohibits autorotation training flights until the hardness of the landing gear rear crosstube (crosstube) is inspected. This AD is prompted by two reports of crosstubes failing during ground handling. These actions are intended to prevent failure of a crosstube, which could result in dropping or tipping of the helicopter.
