The aircraft was being flown in company with a helicopter. While enroute the pilots had been requested to check the surface of Lake Torrens for suitability for future operations. The helicopter was landed on a section of the lake which was assessed as suitable for the fixed wing aircraft. The pilot of that aircraft also assessed the area as suitable and a landing was made at a touchdown speed of 40 knots. Shortly after the nose wheel contacted the surface it began to sink in the soft ground and the aircraft overturned.
