The helicopter flight instructor reported that he was teaching his student to hover.

The helicopter was at a 2-foot hover and began drifting to the left. The left rear skid contacted the ground and a left roll ensued. The student pilot pulled up on the collective, and the instructor attempted to push the collective down. A dynamic rollover occurred, and the helicopter rolled onto its left side.

The flight instructor reported that wind gusts may have been a factor in the accident.

According to the METAR that was being monitored by the flight instructor about the time of the accident, the wind was from 210° at 8 knots. No wind gusts and no convective activity was reported via METAR that day.

The helicopter sustained substantial damage to the tailboom and the main rotor system.

The pilots reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
