| Confidence Rating: |  Accident investigation report completed and information captured |
The certified flight instructor reported that the purpose of the flight was to demonstrate a variety of maneuvers to the student in the helicopter. Near the end of the flight the instructor demonstrated a power-on autorotation; however, he delayed the application of power and did not have sufficient rotor RPM to recover the helicopter before impacting the ground. Upon ground impact, the helicopter's tail rotor drive shaft and main rotor blades were damaged. The pilot reported no preimpact mechanical malfunctions of failures with the airframe or the engine that would have precluded normal operation.
Probable Cause: The certified flight instructor's failure to maintain adequate main rotor RPM during the autorotation.
