NTSB narrative
The pilot had flown the airplane only once before, with another pilot, several months prior to the accident flight. Prior to the accident, the pilot/builder performed several high speed taxi runs, with brief moments of flight just above the runway. The airplane was then observed to climb at an steep angle, bank sharply to the left and descend. One witness, located two houses north of the private grass strip, reported hearing the airplane's engine running until the sound of impact. An second witness, located across from the field where the airplane had taken off, stated that he heard the engine sputtering, then stop running. Examination of the propeller revealed the last several inches of both blades were separated. Examination of the 2 cycle, 4 cylinder, 25 horsepower engine revealed that one of the four carburetors was unsecured from its mount. The pilot had recently replaced all four carburetors.
Probable cause
The pilot's failure to maintain airspeed.

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.
