Before commencing the 17th spreading flight for the day, the pilot noted that one fuel tank indicated empty and the other indicated one quarter full. After a normal take-off and turn at about 150 feet above ground level, the engine lost all power. The pilot was committed to a landing in a small paddock with a downhill slope. Touchdown was made in light tailwind conditions, and during an attempt to turn the aircraft to lengthen the landing distance available, the left wing struck the ground. The aircraft partially ground looped, one tyre was rolled off its rim, and the aircraft came to rest within the confines of the paddock. The pilot then physically checked the fuel tank contents and found that only a few litres remained in one of the tanks, while the other was empty. The loss of engine power was caused by fuel starvation. The pilot had not previously flown the aircraft and was not aware of the time the aircraft had been flown since it had last been refuelled. He did not accurately determine the quantity of fuel in the aircraft prior to commencing the operation, nor did he have any method of determining the duration of the flight. He relied solely on the fuel gauges to determine the quantity of fuel in the aircraft.
