Circumstances:
The aircraft had been carrying out magnetometer survey flights from the airport for several weeks. It departed at 06:30 hours local time, reaching the survey area an hour later. At 07:50 the Doppler equipment became unserviceable and a little later light rain was encountered. The survey work was abandoned and the flight returned to Tennant Creek. At 09:14 the crew radioed that they were in the circuit area. Wind was reported to be from 070° at 14 knots. The acknowledgement of this information was the last contact with the flight. A minute later, the twin engine aircraft crashed in a prairie located 2 miles west of the runway 07 threshold.The aircraft was totally destroyed and all six on board were killed, among them a child aged 11. An examination of wreckage showed that one of the duplicated aileron control chains in the pilot's control column was broken in the region of the control wheel sprocket. A link pin had failed and this pin might have subsequently jammed the assembly as the control wheel was being rotated. Control could not be taken over by the copilot, as there was no copilot on the flight. The right hand cockpit seat and rudder pedals were removed so a crew member was able to gain access to the nose area of the aircraft for the survey work.
Probable cause:
The cause of this accident was a loss of control of the aircraft, and although the evidence available does not permit the reason for the loss of control to be determined, the possibility can not be eliminated that the pilot suffered an impairment of ability and, coincidentally, was deprived temporarily of aileron control.

Circumstances:
The pilot George C. 'Colin' Johnston was performing a flight from Wyndham to Tennant Creek with an intermediate stop in Coolibah, NT. The twin engine aircraft landed at 1210LT and some mail was delivered to the pilot who took off at 1300LT. Shortly after liftoff, while in initial climb, the aircraft banked left and crashed in a huge explosion. The pilot was killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was probably the result of severe turbulences and reduced performance due to a high density altitude.

Circumstances:
The aircraft was being used to ferry the passengers from VH-UXX 'Faith in Australia' which had suffered engine failure near Daly Waters when the Monospar had an engine failure itself. It was en route from Daly Waters to Alice Springs with two passengers on board, two crew members and a crocodile that was destined for the Melbourne Zoo. The crew reduced his altitude and attempted an emergency landing in a uninhabited area located near Woodgreen Station, Northern Australia. Upon landing, the aircraft slid for several yards and hit trees before coming to rest. The engineer walked some 30 miles to the overland telegraph line to find help. All passengers were eventually rescued and they survived as they ate the crocodile.
Probable cause:
Engine failure in flight.
