We propose to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 helicopters. This proposed AD would require inspecting each terminal lug and replacing any lug that has discoloration, corrosion, incorrect crimping, or incorrect installation. This proposed AD is prompted by the discovery that terminal lugs with incorrect crimping may have been installed on these helicopters. The proposed actions are intended to detect incorrectly installed or crimped terminal lugs and prevent contact resistance and reduced gastightness between the wire and terminal lug, subsequent loss of electrical power, and an electrical fire.
The agency’s own summary, as published.
