NTSB narrative
The pilot-in-command reported that 'I had tried to take off with no flaps, thinking I had them down.' The aircraft never became fully airborne, passed through a perimeter fence and then collided with sagebrush during which the nose landing gear collapsed. Post crash examination of the aircraft revealed the flaps in the retracted position. The density altitude at the 4,300 foot long, turf airstrip was 7,325 feet.
Probable cause
The pilot-in-command's not lowering flaps prior to takeoff and overload of the nose landing gear. Contributing factors were high density altitude conditions and high brush.

- 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.
