Airworthiness Directives; Airbus Helicopters Deutschland GmbH

FAA / Federal Register · 2020-24766

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model EC135P1, EC135T1, EC135P2, EC135T2, EC135P2+, EC135T2+, EC135P3, and EC135T3 helicopters. This proposed AD was prompted by a deviation from a new manufacturing process, which resulted in a reduced life limit (service life limit) for certain tail rotor blades. This proposed AD would require a reduced life limit for those tail rotor blades and require a new life limit for certain other tail rotor blades, as specified in a European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
