Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

FAA / Federal Register · 2021-03991

The FAA proposes to supersede Airworthiness Directive (AD) 2016-11-21 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135P1, EC135P2, EC135P2+, EC135T1, EC135T2, and EC135T2+ helicopters. AD 2016-11-21 requires revising the life limit of certain parts and removing each part that has reached its life limit. Since the FAA issued AD 2016-11-21, new models were certified. This proposed AD would expand the applicability to include Model EC135P3 and EC135T3 helicopters. This proposed AD would also revise the life limits for certain parts and propose to remove each part that has reached or exceeded its life limit. The actions of this proposed AD are intended to address an unsafe condition on these products.
