NTSB narrative
During the initial climb after takeoff, the airplane was observed climbing at a steep pitch angle. The airplane's wings rocked back and forth a few times, and then it rolled and dropped to the right. Witnesses described the engine noise as loud and constant until the point of impact. The airplane came to rest inverted in a wooded area about 1,600 feet beyond the approach end, 110 feet to the right of, and at an elevation 40 feet below the departure runway. Examination of the airframe and engine did not reveal any pre-impact mechanical malfunctions.
Probable cause
The pilot's failure to maintain airspeed during the takeoff, which resulted in an inadvertent stall/spin.

- 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.
