Abstract
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Model SA330J helicopters, all serial numbers. This AD was prompted by reports of the failure of the lower bearing cage of the main rotor hub (MRH) flapping hinges and of the presence of metallic particles at the bottom of a drag hinge. This AD requires repetitive inspections of the MRH chip detectors, or for helicopters not equipped with chip detectors, repetitive inspections of the oil for contamination by metallic particles, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
