Analysis

The pilot stated that on departure when the aircraft was 100 to 150 feet above the ground, the engine quit. He made a left turn toward more suitable terrain and the engine started up again. Before he could get set up for a more suitable field, the engine quit again. The aircraft landed just short of a road, hit a ditch and flipped forward to the inverted position. An inspection of the wreckage found that the fuel tank vent port in the top of the tank had been partially blocked during construction. The remainder of the wreckage did not appear to have any pre-impact damage.
