| Confidence Rating: |  Accident investigation report completed and information captured |
The certified flight instructor (CFI) reported that the helicopter was in a 3-foot hover with the student pilot on the controls, when the aircraft began to drift 'slightly' to the right. As the CFI started to correct by applying left cyclic, the student 'abruptly' lowered the collective. Subsequently, the right skid contacted the ground and the helicopter rolled over to the right. A ground impression, corresponding to the right skid was found after the accident. The helicopter's tail boom and main rotor drive system were destroyed and cabin was substantially damaged. The student pilot had received about 4 hours of helicopter instruction at the time of the accident. He held a commercial airman's certificate with single and multi-engine airplane ratings, and was a certified flight instructor for single and multi-engine airplanes.
Probable Cause: The student pilot's abrupt lowering of the collective. Factors were the student pilot's lack of experience in helicopters and the CFI's delayed remedial action.
