## Summary

We propose to adopt 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 proposed AD would require 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 proposed AD is prompted by the uncommanded detaching of a door from an MBB-BK 117 C-2 fuselage. The proposed actions are intended to prevent the in-flight loss of the door, which could damage the helicopter and injure persons on the ground.
