Pilot Report
The pilot reported that the aircraft had 20 gallons of fuel on board at takeoff. After climbing to 10,000 feet for a parachute jump, the aircraft returned to the airport with an estimated 10 gallons of fuel remaining. During a downwind landing, the pilot elected to go around.
Loss of Power and Forced Landing
As the pilot was climbing through about 75 feet above ground level during the go-around, the engine lost power. A forced landing was subsequently made in a small pasture.
Post-Accident Examination
Initially, the mishap was reported as an incident. However, before the aircraft was examined, the wings had been removed and both the aircraft and wings were transported from the accident site. Upon examination, both wing tanks were empty, with the exception of a small amount of 100 low lead (blue) fuel found in the right wing tank. Fluid taken from the lines to the left wing tanks had the appearance of automotive fuel. The owner reported that automotive fuel had previously been used. No fuel was found in the carburetor.
