Aircraft Accident/Incident Report
Spanish Fork, Utah 84049

NTSB Narrative Summary Released at Completion of Accident
During a practice hover autorotation, the helicopter touched down hard, bounced, and experienced a dynamic rollover. The student performed three hovering autorotations without incident. The student properly entered the fourth autorotation, which was to be the last of the flight. The student then made several cyclic input changes and the helicopter touched down on the left skid, resulting in the helicopter bouncing back airborne. The student reacted by inputting left pedal followed with abrupt right forward cyclic movement. The helicopter drifted right and began to pivot around the front portion of the right skid. The CFI assumed authority of the flight controls in attempt to regain directional control; however, the helicopter continued rolling over on its right side. The CFI reported no mechanical malfunctions or failures with the helicopter prior to impact.
NTSB Probable Cause Narrative
The student pilot's improper use of the flight controls, which induced a dynamic rollover. Also causal was the certificated flight instructor's inadequate supervision and delayed remedial action.
