During the airplane's takeoff roll, two witnesses reported that the engine sounded unusual; the airplane became airborne and flew in ground effect until it reached the end of the runway and then pitched up abruptly. As the airplane reached about 500 feet agl, the engine sputtered and the airplane made a hard-left turn and pitched down. After the loss of engine power, the pilot likely initiated a return to the runway environment, during which the airplane impacted terrain. The airplane was heard regaining power as it descended below the tree line, just prior to impacting the ground.
In a postaccident examination, the electric fuel pump was found seized with contaminants inside the internal fuel passages.
The contaminants were determined to be consistent with a mixture of fuel additives such as anti-static and anti-corrosion additives. It is likely that, during the takeoff, the electric fuel pump seized due to the fuel contamination and restricted fuel flow to the engine. The engine then experienced a degree of fuel starvation which resulted in reduced engine power.
Probable Cause: The pilot's failure to maintain control after the partial loss of engine power. Contributing to the accident was a contamination of the fuel system, which likely seized the electric fuel pump and restricted fuel flow to the engine.
