NTSB narrative
The private pilot was practicing takeoffs and landings to a taxiway. The pilot reported that, during his fourth landing attempt and as he was transitioning to a hover, he noticed that the helicopter's main rotor rpm was slightly low, and he attempted to increase the rpm by adding power. However, the helicopter did not respond and settled onto the taxiway. The pilot then raised the collective to bring the helicopter back to a hover, but the rotor rpm was still low. The pilot continued to try and add power, but the helicopter drifted right, and the right skid then contacted the ground off the side of the taxiway, which resulted in a dynamic rollover and substantial damage to the airframe and rotor blades.
The pilot stated that he was new to this type of helicopter, and it is likely that he allowed the main rotor rpm to decay to a point from which he was unable to recover. He stated that there were no preaccident mechanical anomalies with the helicopter that would have precluded normal operation.
Probable cause
The pilot's failure to maintain sufficient main rotor rpm, which resulted in a loss of helicopter control and 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.
