The student's improper use of the anti torque pedals during a practice hover autorotation, which resulted in the helicopter rolling over. Additional causes of the accident were the certificated flight instructor's inadequate supervision of the maneuver and delayed remedial action.

Read the full NTSB narrative

The student pilot made several approaches and a practice hover autorotation before repositioning the helicopter to a different area of the airport. They planned to perform more hover autorotations and the certified flight instructor (CFI) continued to guard the flight controls. The CFI initiated the hover auto without communication, which was a deviation from their normal procedures. In response to the movement the student depressed the left [improper] anti-torque pedal and the helicopter began to spin. The CFI could not regain control and the helicopter rolled. The CFI reported no pre impact mechanical malfunctions or failures with the helicopter
