NTSB narrative
The flight instructor in the skid-equipped helicopter reported that the purpose of the flight was to conduct an aircraft transition flight. The pilot under instruction performed a touchdown autorotation on the asphalt runway. The helicopter touched down in a level attitude just right of the centerline and then slid on its skids off the right side of the runway into grass. The helicopter spun right and rolled onto its left side.
The helicopter sustained substantial damage to the main and tail rotor drive systems.
Both pilots reported that there were no mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
Probable cause
The pilot under instruction's failure to maintain directional control and the flight instructor's delayed remedial action.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
