NTSB narrative
The pilot reported that he was attempting to perform a crosswind, soft-field takeoff from a dry, turf airstrip. He set the flaps to 10°, and the airplane was in a nose-high attitude until the stall warning horn sounded. He then relaxed pressure on the yoke until the stall warning horn stopped. Shortly after liftoff, the airplane entered a power-on stall, and the pilot lost airplane control, and the airplane then began to descend to the runway. The airplane subsequently departed the runway and impacted a barbed wire fence.
The airplane sustained substantial damage to the right wing strut.
The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot's exceedance of the airplane’s critical angle of attack, which resulted in a power-on stall and subsequent loss of airplane control.

- 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.
