Probable cause

The pilot's inadequate maintenance and servicing of the aircraft. A factor was water contamination in fuel tank.

Analysis

The vintage airplane was making takeoff and landings when, on its second takeoff, the powerplant failed due to fuel contamination. The airplane glided straight ahead and crashed into the trees. Post crash investigation by the FAA revealed rust and scale in the fuel tanks which had been recently cleaned by the pilot. This contamination was not noticed by the pilot during his preflight inspection.
