The pilot stated that after completing the normal start-up and pre-flight procedures, he established that the area was clear and picked up into a 6 - 8 foot hover. He reported that he began to move away from the hangar. He stated that as he did so the passenger in the left front seat turned to his right and "accidentally and inadvertently hit or bumped the counterweight portion of the cyclic as he turned."
The pilot stated that the helicopter drifted toward the open hangar door and before he could correct the drift the main rotor clipped the bottom edge of the door. He recalled: "I quickly maneuvered away from the hangar building and began to level the aircraft." The helicopter descended to the ramp. The subsequent hard landing caused the skids to collapse and the main rotor to sever the tail boom.
A ground witness to the accident submitted a video recording of the accident flight. Review of the recording revealed that after the helicopter lifted-off, it paused in a hover for a few seconds and then began to climb out, subsequently contacting the door. No drift toward the hangar building was observed prior to rotor blade contact with the door.
