Summary
Final rule; request for comments.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH (AHD) Model MBB-BK 117 C-1 helicopters. This AD was prompted by a report of a louver box assembly detaching in flight due to incorrect installation. This AD requires repetitively accomplishing a play check of the affected louver box assembly and, depending on the results of the check, accomplishing corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
