Incident Details
A helicopter was being used for training purposes involving a taxi/hover autorotation maneuver. The student pilot was at the controls, with a certified flight instructor (CFI) present.
Sequence of Events
During the practice, the helicopter settled onto a soft area of turf. The student pilot over-controlled with the right anti-torque pedal, resulting in the helicopter settling onto its left skid. The CFI attempted remedial action but was unable to overpower the student's input. After touchdown, the left skid sank into the soft terrain, causing the helicopter to roll over.
Findings
The helicopter rolled over after the left skid sank into the soft ground. No further details were provided in the source.
