NTSB narrative
The pilot said that he was practicing touch-and-go landings. After one of the takeoffs, he pulled the throttle back to practice an aborted takeoff from an altitude of 50 feet above ground level (agl). He lowered the flaps and performed a three-point landing. He added power for takeoff again, but had only climbed 3 feet agl before impacting a 4-foot fence at the end of the 3,675-foot-long gravel runway. The airplane came to rest upright with its left main landing gear bent back under the fuselage. The left wing sustained structural damage.
Probable cause
The pilot's failure to maintain clearance from a fence at the end of the runway.

- 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.
