| Confidence Rating: |  Accident investigation report completed and information captured |
The commercial pilot reported that during takeoff, the helicopter rolled to the right, and he was unable to arrest the roll with cyclic input. The right skid and main rotor blades struck the ground, and the helicopter spun 360° before it came to rest upright with the tail rotor assembly severed from the tailboom. Postaccident examination of the flight control system revealed flight control continuity with no evidence of mechanical malfunctions or failures that would have precluded normal operation. In addition, the pilot reported that there were no mechanical malfunctions or failures with the helicopter at the time of the accident. Thus, it is likely that the pilot failed to maintain helicopter control while maneuvering during takeoff.
Probable Cause: The pilot's failure to maintain helicopter control while maneuvering during takeoff.
