Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

FAA / Federal Register · 2021-26497

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-2 helicopters. This AD was prompted by a report of chafing marks on a wiring harness near the locking washer of the lateral control rod. This AD requires 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
