NTSB narrative
The flight instructor reported that he lifted off in the helicopter and ascended to between about 3 and 4 ft above the grassy field north of the runway to show the student pilot how to hover, and while having positive control of the collective and antitorque pedal, he gave the cyclic control to the student. While the instructor was "guarding" the cyclic, the student applied right cyclic. Subsequently, the helicopter descended, and the right skid contacted the ground. The instructor applied left cyclic, but the helicopter dynamically rolled over. The helicopter sustained substantial damage to the main rotor system and horizontal stabilizer. The instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable cause
The student pilot's improper cyclic input while hovering and the flight instructor's delayed remedial action, which resulted in a dynamic rollover.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
