Incident Overview
During a helicopter training flight, a student pilot was practicing hovering maneuvers under the supervision of a flight instructor, who was applying light pressure on the controls. The helicopter began to drift to the left, and the student allowed the aircraft to settle. The instructor waited for the student to take corrective action, then verbally instructed the student to do so. When the student did not respond, the instructor initiated corrective control inputs.
Sequence of Events
As the instructor began to correct the left drift, the left skid of the helicopter made contact with the ground. This contact caused the helicopter to start rolling to the left. The instructor attempted to counteract the roll, but the efforts were unsuccessful. The helicopter continued to roll left until it came to rest on its side.
Cause Determination
The instructor attributed the roll event to dynamic rollover, stating that dynamic rollover was the cause of the roll. No other causal factors were identified in the report.
Aftermath
The helicopter sustained damage during the rollover. The report did not specify the extent of damage, the operator, or the helicopter model and registration. No information regarding injuries or weather conditions was provided.
