Minneapolis-St Paul Internatio Airport
Aircraft Accident/Incident Report

Minneapolis, Minnesota 55450
Friday, December 10, 2010 17:20 CST

NTSB Narrative Summary Released at Completion of Accident

The cabin entry door separated from the airplane during climb and was found about 6 miles from the departure airport. The airplane returned to the departure airport and landed without further incident. The door handle was found to be in the latch position and not in the lock position. Postaccident examination of the airplane revealed no anomalies that would have precluded normal operation of the door system.

NTSB Probable Cause Narrative

The pilot's failure to follow the aircraft checklist in locking the cabin door prior to departure which resulted in its in-flight separation.
