NTSB narrative

**This report was modified on July 17, 2020. Please see the docket for this accident to view the original report.** The flight instructor reported that he was teaching his student to hover in the helicopter. The helicopter was in a 2-ft hover and began drifting to the left. The left rear skid got caught in a crack in the runway, and the helicopter rolled left. According to the flight instructor, the student pilot pulled up on the collective, and the instructor attempted to push the collective down; however, the student pilot reported that he was not aware the flight instructor had transferred control of the helicopter to him and was "tracking the progress of the flight instructor." 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 the flight instructor was monitoring about the time of the accident, the wind was from 210° at 8 knots. The METAR reported no wind gusts and no convective activity 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.
