NTSB narrative
During his first time operating the newly-assembled airplane, the pilot/airplane builder performed a series of high-speed taxi tests on the taxiway. The pilot stated that, after traversing the length of the taxiway several times, the airplane became airborne in the gusty wind. The pilot increased the engine power, and the airplane continued to ascend. He maneuvered near the airport for about 10 minutes and then decided to return. While on final approach to the runway, the airplane was unstable, and the pilot performed a go-around. On the second approach, with the airplane about 30 feet above ground level, the pilot lost control, and the airplane descended in a nose-low attitude into the terrain. The pilot reported no mechanical malfunctions or failures with the airplane that would have precluded normal operation. About the time of the accident, the wind was reported to be at 9 knots, gusting to 19 knots.
Probable cause
The pilot’s failure to maintain control of the airplane while on final approach, which resulted in an aerodynamic stall.

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.
- API snapshot SHA-256: b57718b4c7859f0cd6b5ba7390a21d09ccbbab24b5210f2f7a49fcb72db7c34e; retrieved 2026-09-15T18:15:40.826Z.
