Probable cause
loss of engine power due to a leaking carburetor and an inoperative float, and the pilot's failure to maintain aircraft control during the restart attempt. Contributing factors were the sudden engine power surge during the attempted restart, and unsuitable terrain on which to make a forced landing.

When the airplane turned downwind, the engine lost power. The pilot attempted to restart the engine, and it surged suddenly. The torque caused the airplane to roll inverted. The pilot managed to roll the airplane upright, but was unable to restart the engine and he made a forced landing on airport property, striking the ground hard and substantially damaging the airplane. Examination and tesing of the carburetor revealed the enrichment cover was leaking, and there was "a substantial leak" at one of the vapor vent ports. One of the vapor vent floats was not functioning. When the vapor vent port was plugged, the carburetor tested between 7 and 22 pounds per hour above the rich limit.
