| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that, while maneuvering the helicopter at low altitude for an agricultural application flight, an unsecured clipboard that was on the seat next to him fell and became lodged under the antitorque pedals. Unable to free the clipboard, the pilot chose to make a precautionary landing. About 5 to10 ft above ground level, the pilot lost tail rotor authority, and the helicopter began to rotate to the right. After about two rotations, he was able to land the helicopter. During the touchdown, the stinger folded into the tail rotor.
The helicopter sustained substantial damage to the tailboom.
The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
Probable Cause: The pilot’s failure to secure a loose item inside the cockpit that interfered with antitorque pedal control and led to a loss of helicopter control due to a loss of tail rotor effectiveness.
