- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot had just taken off from his private airstrip and did not believe that he could clear the trees at the end of the runway. The pilot decided to make a landing in an adjacent field that would require a turn of approximately 150 degrees. The pilot stated that the steep turn required resulted in a stall and subsequent nose down impact with the ground. The runway surface consisted of dry sod six inches high, which the pilot stated as a reason that the airplane did not reach rotation speed as soon as normal. The runway is approximately 965 feet long and 75 feet wide with high trees approximately 350 feet from the departure end of the runway. There is a slight uphill grade to the runway.
Probable cause
the pilots inadequate preflight planning and his failure to maintain airspeed. Factors to the accident were the high trees at the departure end of the runway, and the stall encountered.

- 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.
