We propose to supersede Airworthiness Directive (AD) 2017-02- 07 for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 and Model MBB-BK 117 D-2 helicopters. AD 2017-02-07 currently requires a repetitive inspection and a one-time torque of each hydraulic module plate assembly attachment point (attachment point). Since we issued AD 2017-02-07, a terminating action has been developed to address the unsafe condition. This proposed AD would retain the initial inspection and torque requirements of AD 2017-02-07 and require replacing the attachment point hardware. The actions of this proposed AD are intended to prevent an unsafe condition on these products.
