Airworthiness Directives; Airbus Helicopters

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC 130 T2 helicopters. This AD was prompted by the determination that helicopter operators received main rotor blades (MRB) that are not certified to be installed on their helicopters and thus, without instructions for continued airworthiness, cannot be properly maintained. This AD requires replacing the affected parts with serviceable parts and prohibits installing the affected MRBs on Airbus Helicopters Model EC 130 T2 helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
