NTSB narrative
The pilot reported that the purpose of the flight was to move the helicopter off of a trailer onto the ground. As the helicopter began to lift off from the trailer platform, a steel bolt on the landing gear skid caught on the aluminum trailer skirting. The helicopter experienced a dynamic rollover and came to rest on its right side. Shortly thereafter, a fire erupted and the cabin area was consumed.
The pilot stated that there were no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
Probable cause
The pilot's failure to maintain aircraft control after the helicopter's skid catching on the side of a trailer during takeoff, 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.
