Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters

FAA / Federal Register · 2021-13128

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 D-2 helicopters. This AD was prompted by reports of chafing marks on the wiring harness behind the middle side panels in the area of the front passenger (PAX) panels. This AD requires inspecting, modifying, and rerouting the wiring harness, 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.
