Circumstances:
At a height of about 200 feet after take-off the right engine lost power. The pilot feathered the propeller and commenced a gentle left turn in order to return to the strip. He later advised that the aircraft began to sink towards some large trees and he was forced to increase the angle of bank in an effort to avoid them. Shortly afterwards the aircraft struck the ground heavily in an adjacent paddock about 1 kilometre from the strip.
Probable cause:
The engine failure was caused by jamming of accessory drive gearing as a result of the effects of excessive wear within a magneto. It was probable that a mandatory inspection of the magneto which fell due 84 flying hours before the accident, was not conducted. On take-off the aircraft weight exceeded the authorised limit, however following the engine failure the pilot was able to maintain straight and level flight. A cleared area of ground lay ahead and just to the left of the flight path but the pilot had considered the aircraft had sufficient performance capability to permit a return to the trip.

Circumstances:
The aircraft departed Polo Flat at 0750 hours on a planned flight to Khancoban, Talbingo and return. There was dense fog at Polo Flat at this time and the aircraft took off and climbed through fog until it was in clear conditions above. At Cooma Aerodrome, fog which had existed earlier dissipated about 0715 hours and the weather at that location then remained clear. When the aircraft returned to the Polo Flat area shortly after 0930 hours, fog was still present but it was commencing to break with patches of blue sky visible from time to time. Information regarding the weather conditions was communicated to the, pilot who had established radio contact with the base operations officer at Polo Flat. Shortly after the aircraft arrived in the area it was observed to make what appeared to be a landing approach into the north but when it had descended to a height of 10 to 15 feet the approach was discontinued and it climbed away. After flying for some time above the fog at a height of about 500 feet the aircraft was heard approaching from the south and the operations officer heard the pilot transmit the words 'hit the...'. Shortly afterwards the sound of an impact was heard. The port wing of the aircraft had struck the radio transmitter mast 32 feet from the top and the aircraft crashed to the ground in a steep nose-down attitude some 146 metres north of the mast. A fierce fire developed shortly after impact.
Crew:
John Howard, pilot.
Passengers:
Evelyn Anne Harvey,
Patricia Joy Harvey.
Probable cause:
The probable cause of the accident was that the aircraft was operated at an unsafe height in weather conditions in which the pilot was not able to maintain the visual reference necessary to ensure adequate clearance from obstructions.
