Preflight and Fuel Estimation
During a preflight inspection, the pilot visually checked the fuel tanks and estimated that 10 to 20 gallons of fuel remained in both the left and right tanks. The start, taxi, and run-up were performed using the right tank.
Fuel Gauge Anomaly and Takeoff
The right fuel gauge reading suddenly went to zero. Although the pilot suspected a faulty reading, he selected the left tank for takeoff.
Power Loss and Emergency Landing
After takeoff, while climbing through approximately 200 feet above ground level, the engine lost power. The pilot switched to the right tank but observed no response. He then switched back to the left tank and performed a gear-down landing in an alfalfa field.
Post-Accident Examination
An examination of the aircraft revealed 12 to 15 gallons of fuel remaining in the left tank. The right tank was found empty. No part failure or malfunction was identified.
