Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model SA330J helicopters. This proposed AD was prompted by a report of a main rotor gearbox (MGB) flange assembly coupling (coupling) that was incorrectly assembled. This proposed AD would require a one-time visual inspection to determine correct assembly of each sliding flange installed on each MGB coupling, and if necessary, further corrective actions. This proposed AD would also prohibit installing certain MGB couplings or any MGB equipped with certain MGB couplings on any helicopter. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
