Shortly after takeoff for the third aerial agriculture flight of the day, the pilot reported that the engine began to lose power. The pilot dumped the load, then after several unsuccessful attempts to regain power, landed the aircraft in a paddock. During the landing roll, soft ground was encountered and the aircraft overturned. The engine was later run on a testbed but no faults were found. The weather at the time of the accident was humid, with a temperature of 23-25 degrees Celsius, which may have contributed to carburettor icing.
