Airbus Helicopters Deutschland GmbH (AHD) Helicopters
This AD applies to Airbus Helicopters Deutschland GmbH (AHD) MBB-BK 117 D-3.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 D-3 helicopters. This AD was prompted by a determination that certain bolts installed on the horizontal control rods of the flight controls were not dye penetrant inspected for cracks during manufacturing and thus could lead to bolt failure. This AD requires replacement of affected bolts with bolts that are eligible for installation. This AD also prohibits installing an affected bolt on any helicopter. The FAA is issuing this AD to address the unsafe condition on these products.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
