## Abstract

We are adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 C-2 (including configuration C-2e) and MBB-BK 117 D-2 helicopters. This AD requires replacing the main rotor (M/R) blade vibration absorbers. This AD was prompted by a report of strong M/R blade vibrations on a Model MBB-BK 117 C-2 helicopter. The actions of this AD are intended to prevent an unsafe condition on these products.
