NTSB narrative
The airplane stalled after takeoff and collided with a tree. The pilot stated that he previously ground looped the airplane in December 2006, which resulted in the necessity to replace the left wheel assembly. A borrowed left wheel assembly was installed with the brake drum facing outboard, rendering the left brake inoperative. The purpose of the accident flight was to perform taxi testing at increasing speeds in an effort to determine rudder effectiveness, and also for personal experience; no static engine run-up was performed before applying power to begin the taxi test. The airplane was taxied onto runway 15, and power was applied to begin the taxi test, but the airplane inadvertently became airborne. After realizing that the flight was airborne and there was insufficient runway remaining to land and stop the airplane, he applied full power and attempted to turn 45 degrees in order to land on a closed grass runway. The airplane climbed in ground effect, stalled, and collided with trees. He reported that the "...engine was 'overpropped' and thus not producing maximum horsepower." He also recommended more static testing of the engine/propeller combination.
Probable cause
The failure of the pilot to abort the takeoff after becoming airborne during taxi testing, and the failure of the pilot to maintain airspeed after becoming airborne resulting in an inadvertent stall, uncontrolled descent, and in-flight collision with a tree.

- 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, coordinates. 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.
