## Abstract

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 helicopters. This AD requires inspecting each terminal lug and replacing any lug that has discoloration, corrosion, incorrect crimping, or incorrect installation. This AD was prompted by the discovery that terminal lugs with incorrect crimping may have been installed on these helicopters. The actions of this AD 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.
