NTSB Narrative Summary Released at Completion of Accident

According to the pilot, the right door opened during takeoff; he lost control of the helicopter while attempting to secure the door. The helicopter impacted the ramp, the skids separated, and the firewall and tail rotor sustained substantial damage. The pilot reported that there were no mechanical failures or malfunctions prior to the accident. He stated that, prior to departure, he checked the security of the door with elbow pressure but postulated that the securing pin was not fully engaged.

NTSB Probable Cause Narrative

A loss of control due to the pilot's diverted attention as a result of an open door.
