Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters

FAA / Federal Register · 2021-13710

The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK117 C-2 and MBB- BK117 D-2 helicopters. This AD was prompted by a report of increased control force in the collective axis. This AD requires repetitive visual inspections of the main rotor actuator (MRA), 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.
