Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

FAA / Federal Register · 2021-19614

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. This proposed AD was prompted by a report of chafing marks on a wiring harness near the locking washer of the lateral control rod. This proposed AD would require an inspection of the wiring harness and the routing of the wiring harness and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
