Analysis

After making a swath run the aircraft pulled up to clear power lines. Witnesses state that the engine cut out and aircraft pitched nose down and began to rotate. They state that the engine regained power just prior to impact. Subsequent investigation failed to reveal any mechanical discrepancies that would have contributed to the accident. Conditions were not conducive to carb ice and fuel was found at the site in the lines leading to the engine.
