- What it does
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA 365 N helicopters. This AD was prompted by reports of tightening torque loss on the input flange nut due to circular wear on the faces of the flange, the slip ring, and the input flange. This condition, if not addressed, could lead to degradation or jamming of the input roller bearings and loss of yaw control of the helicopter. This AD requires repetitive functional inspections (checks) and, depending on the results of the inspections, corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
