NTSB narrative
The pilot reported that the purpose of the flight was to demonstrate the helicopter's performance at an air show. He traveled from overseas by scheduled airline, arriving 2 days before the air show. The day before the air show he flew the helicopter for 50 minutes of demonstration practice at a similar density altitude to that anticipated for the following day's performance. The accident flight began about 1315, and the first two maneuvers were completed without incident. The third maneuver was "a standard 180-degree 'wing-over' commenced from a standard 300 feet." According to the pilot, the helicopter "failed to fully recover from the descent phase of the maneuver and struck the surface at approximately 40-50 knots." The helicopter rolled onto its left side. The pilot reported that the density altitude at the time of the accident was 8,500 feet. He stated that the accident could have been prevented "possibly by greater awareness and practice at the local density altitude conditions."
Probable cause
The pilot's failure to maintain terrain clearance while maneuvering. A contributing factor was the high density altitude.

- 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, coordinates. 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.
