Abstract
The FAA is adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 D-2 helicopters. This AD was prompted by a report of a broken Titanium (Ti) bolt. This AD requires removing certain Ti-bolts from service and prohibits installing these Ti-bolts in a critical area. The FAA is issuing this AD to address the unsafe condition on these products.
