NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
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.
The National Transportation Safety Board determines the probable cause(s) of this
The pilot under instruction's failure to maintain directional control and the flight instructor's delayed remedial action.
