Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-2 and MBB- BK 117 D-2 helicopters. This AD was prompted by a determination that a certain part-numbered standard MS18027 type hook may be subject to localized yielding in the mating threads when assembled to higher assembly torques. This AD requires modifying and re-identifying the affected part or replacing the affected part with a serviceable part. This AD also prohibits installing an affected part on any helicopter unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.
