## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2009-25-09 for Eurocopter France (now Airbus Helicopters) Model SA 330 F, G, and J helicopters. AD 2009-25-09 currently requires re-adjusting the torque of the main gearbox (MGB) flexible coupling bolts. Since the FAA issued AD 2009-25-09, Airbus Helicopters has modified the MGB overhaul and repair procedures, which corrects the unsafe condition. Additionally, the FAA-validation for Model SA330F and G helicopters has been cancelled. This proposed AD would retain the requirements of AD 2009-25-09 but would revise the applicability by excluding Model SA330F and G helicopters and exclude MGBs that have been subject to the modified procedures. The actions of this proposed AD are intended to address the unsafe condition on these products.
