Background
The pilot-in-command reported that the aircraft was very low on fuel before departure. He had 10 gallons added to each wing tank prior to departing Madison, Georgia. The flight then proceeded to Greensboro, Georgia, for sales demonstration flights.
First Demonstration Flight
During the first demonstration flight, the aircraft performed well except for an issue with the carburetor heat control. The control became jammed in the 'on' position during the landing. The pilot managed to move it to the 'off' position before beginning the second demonstration flight.
Second Demonstration Flight
During the takeoff of the second demonstration flight, the engine lost power at approximately 100 to 150 feet above ground level (AGL). The pilot subsequently performed an emergency landing, during which the aircraft struck trees.
Investigation Findings
An investigation of the aircraft's fuel system found virtually no fuel in several key components. Specifically, the engine-driven fuel pump, carburetor, electric boost pump, main fuel strainer, fuselage header tank, and associated lines contained negligible fuel.
