What happened
During the takeoff roll, the pilot reported that the engine experienced a loss of partial power just after the aircraft had lifted off from the runway. The pilot maintained a straight flight path, passing underneath power lines located near the end of the airstrip.
As the flight continued, the tailwheel of the aircraft struck a barbed wire fence. Following this impact, the airplane touched down in a field containing small Christmas trees. The sequence of events concluded when the airplane nosed over before coming to a complete stop. The pilot was not injured during the accident.
The investigation
An inspection of the engine following the accident did not identify any evidence of mechanical failure or malfunction. However, investigators discovered contamination within the carburetor. Additionally, the investigation determined that the accelerator pump failed to function as intended.
