| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that he intended to perform a straight-in autorotation that would terminate with a power on recovery procedure over the runway. The autorotation was performed without incident; however, the pilot did not advance the engine power in time for the recovery. The helicopter impacted the runway hard and came to rest upright on the skids. During the impact sequence, the main rotor blades contacted and severed the tail boom, which resulted in substantial damage.
Probable Cause: The pilot's failure to apply power during the recovery procedure for the practice autorotation, which resulted in a hard landing.
