## Abstract

We are adopting a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (Eurocopter) Model MBB-BK 117 C-2 helicopters with a jettisonable sliding door (door) installed. This AD requires inspecting the lock release assembly and the middle and upper lever locking bolts of each door, replacing any damaged parts with airworthy parts, and ensuring the door is correctly installed. This AD was prompted by the uncommanded detaching of a door from an MBB-BK 117 C-2 fuselage. The actions of this AD are intended to prevent the in- flight loss of the door, which could damage the helicopter and injure persons on the ground.
