Summary
We are adopting a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB-BK 117 D-2 helicopters. This AD requires amending the rotorcraft flight manual to establish a minimum airspeed limitation for the autopilot cruise height mode. This AD is prompted by two reports of uncommanded helicopter climbs and descents. The actions of this AD are intended to address an unsafe condition on these products.
