The pilot had planned to land at a strip on a property 19 kilometres west of the town, however due to the unknown condition of the surface of the strip, he elected to land at the township strip. On the following day, the pilot inspected the strip using a vehicle to test the surface. Due to a soft wet surface at the northern end, 110 metres of the strip was not available. The pilot assessed the remainder of the strip to be firm enough for his planned operation. The pilot flew the aircraft to the strip and during the landing roll, towards the northern end, the nosewheel dug into the surface and the aircraft overturned. There was evidence of sudden heavy braking during the landing roll, immediately prior to the nosewheel digging into the strip surface. It is considered that the sudden application of heavy braking may have caused the nose of the aircraft to pitch down. The nosewheel broke through the surface of the strip and soft damp soil compacted to stop the nosewheel rotation causing the nosewheel to dig in further and the aircraft to overturn. This accident was not the subject of an on scene investigation.
