Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

摘要

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This AD requires altering and re- identifying the overhead panel shock mount assembly (shock mount). This AD was prompted by the manufacturer's stress recalculations. The actions of this AD are intended to correct an unsafe condition on these products.
