Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for certain Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 D-2 helicopters. This AD requires replacing the rescue hoist cable cut pushbutton flip guard (flip guard). This AD was prompted by reports of unintended lifting of several flip guards. We are issuing this AD to address the unsafe condition on these products.
