Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 D-2 helicopters. This proposed AD would require replacing the rescue hoist cable cut pushbutton flip guard (flip guard). This proposed AD is prompted by reports of unintended lifting of several flip guards. The actions of this proposed AD are intended to correct an unsafe condition on these products.
