Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

摘要

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 helicopters. This proposed AD would require establishing or reducing the life limit of various parts. This proposed AD is prompted by recalculations. The actions of this proposed AD are intended to address an unsafe condition on these products.
