VH-SPP departed Cloncurry on a low level aero-magnetic survey flight at the estimated time of 0730 EST with an endurance of about 7 hours. The aircraft was due to return to Cloncurry by 1230 but failed to arrive. Attempts were made to contact the aircraft throughout the afternoon before it was declared overdue at about 2030. The burnt-out wreckage of the aircraft was found by search aircraft the following morning about 9 km north of the survey area and 30 km south of Cloncurry.

The aircraft had struck the ground in a nose-down, inverted attitude. It bounced from this position and came to rest upright, facing the opposite direction. At impact, the left propeller was in the feathered position and fuel to this engine had been shut off. The right engine was operating normally at impact, with fuel being fed from the centre tank.

The investigation revealed that, apart from a 2-hour flight the previous day, the pilot had no other experience in SPP. It was also revealed that there were two significant differences between the fuel system in SPP and that of other Aero Commander models the pilot had flown. These differences concerned the time taken for the outboard fuel tanks to empty and the orientation of the cockpit fuel selector switches.

The analysis concludes that these differences probably led to mismanagement of the fuel system by the pilot and to failure of the left engine due to fuel starvation, followed a short time later by failure of the right engine, also due to fuel starvation. It is possible that the pilot realised what had happened and was able to restart the right engine but not before the performance of the aircraft had deteriorated to such an extent that control of the aircraft with one engine operating could not be maintained.
