NTSB narrative
Witnesses reported that the agricultural airplane attempted to depart the private airstrip with a load of potash, but that the airplane "never made it off the ground" and impacted crops and terrain located at the end of the runway. The airplane nosed over and came to rest inverted. The rudder was crushed and the engine separated from the airframe. The pilot did "not remember any of the accident." The accident flight was one of several flights completed that day and the day before. The estimated weight of the airplane at the time of takeoff was 11,200 lbs, and the airplane's maximum gross weight was 12,500 lbs. The runway is approximately 1/2 mile in length with 1,600 feet of asphalt and the remaining runway is grass/turf. Postaccident examination revealed no anomalies with the airplane.
Probable cause
The pilot's failure to abort the takeoff resulting in a runway overrun and impact with terrain.

Source notes (4)
- 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.
