Abstract
We are adopting a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model EC130 B4 helicopters with a cabin vibration damper installed. This AD requires installing a vibration damper casing assembly on both sides of the helicopter. This AD was prompted by a crack and failure of a cabin vibration damper blade. The actions of this AD are intended to modify the cabin vibration damper assembly to prevent contact with the flight controls in the event of a cabin vibration blade failure, jamming of a flight control, and subsequent loss of control of the helicopter.
