Circumstances:
The aircraft was completing a flight from Lae to Port Moresby, carrying three crew members and 26 cadets of the PNG Army. After passing over Wau in good weather conditions, the pilot decided to enter the Kudjeru Gap Valley when the weather conditions worsened rapidly with clouds up to 10,500 feet. At an altitude of 5,000 feet while trying to gain height, the right wing struck trees and the aircraft crashed on the slope of a mountain, about 50 meters below the summit. The wreckage was found three days later. Five injured passengers were evacuated but one of them died from his injuries.
Probable cause:
The pilot entered an area of low visibility and the accident was the consequence of a controlled flight into terrain.

Aircraft flight hours:

Circumstances:
The aircraft departed Adelaide-Parafield Airport on a charter flight to Moomba, carrying seven passengers and a passenger on behalf of Santos Ltd. At the time of the accident, it as owned and operated by Ansett Transport Industries (Operations) Pty Ltd trading as Ansett General Aviation. During initial climb, while flying in clouds at an altitude of 700 feet heading 270°, the twin engine airplane went out of control, entered a left turn and subsequently stuck the ground at high speed in a shallow dive, some 13 miles northeast of Adelaide Airport. The airplane disintegrated on impact and all eight occupants were killed. The accident was not survivable.
Probable cause:
The cause of the accident was that control of the aircraft was lost and recovery was not effected before it struck the ground. The reason for the loss of control and the inability to take effective recovery action has not been determined. Although the aircraft was operating in cloud from a height of about 700 feet after takeoff until it emerged at a height of 300 to 500 feet above the terrain shortly before impact, there is no evidence of any meteorological condition which may have contributed directly to the accident.

Circumstances:
The four engine airplane departed Hao Island Airport runway 12 at 0500LT for a weather reports mission of seven hours and 40 minutes. During initial climb, both right engines n°3 & 4 lost power simultaneously. The pilot-in-command was able to complete a low pass over the airport before the airplane went out of control and crashed into the sea few hundred meters offshore. The aircraft was destroyed and all six occupants were killed.

Lt Frugier, copilot,
Cpt Parage, navigator,
Adj Hecq, refueling operator.
Passengers:
- Adj Langlais, weather specialist,
1st Mst Saucillon, weather specialist.
Probable cause:
It is believed that the loss of power on both right engines was the consequence of a bleed valve failure. Nevertheless, investigations revealed several engine problems on other aircraft operated in the area, probably due to an excessive exposure to a salty environment.

Circumstances:
The crew was completing a cargo flight from Madang to Mendi. While approaching Mendi Airstrip, a failure of the hydraulic system forced the crew to return to Madang for a safe landing. After touchdown, the airplane was unable to stop within the remaining distance, overran and came to rest in a lake. All three occupants escaped uninjured while the aircraft was damaged beyond repair. The hydraulic failure caused the braking system to be inoperable.
Probable cause:
Failure of the hydraulic system.

Circumstances:
At approximately 0745 hours Central Standard Time on 20 January 1972, there was an in-flight fire in a Beech 65-80 Queen Air aircraft, registered VH-CMI, which resulted in the separation of the starboard engine and the starboard outer wing. The aircraft subsequently struck the ground some seven miles south-west of Alice Springs Airport in the Northern Territory. At the time of the accident, the aircraft was engaged in operating a charter flight for the purpose of carrying passengers, mail and freight from Alice Springs to Ayers Rock. The aircraft was destroyed by fire and impact forces and the pilot and the six passengers were killed.
Probable cause:
The probable cause of the accident was that, following an engine failure which resulted in severe vibration and a fire in the outboard rear section of the engine compartment, the integrity of the firewall and its attached exhaust ducting was lost and structure at the rear of the engine nacelle was thereby exposed to fire.

Circumstances:
The area to be seeded was a flooded rice paddy, rectangular in shape and approximately 1,650 feet east/west by 800 feet north/south, with the western bank 95 feet to the east of a river. There was an extensive area of dense timber, generally about 70 feet in height, on the western side of the river and a line of trees along the eastern bank. After making an aerial inspection of the area the pilot arranged for the two men who were to act as markers to take up positions on the banks of the paddy in preparation for easterly and westerly seeding runs commencing along the southern side. The first run was made into the east, approaching over the timbered area and towards the low sun. run was then made to the west followed by a steep pull-up and turn over the trees. The third run, again into the east, was commenced but no seed was dropped on this occasion possibly because of difficulties in observing and lining up with the marker at the western end of the paddy. The next run was to the west and was apparently normal and this was followed again by a steep pull-up and turn over the trees. Towards the end of the turn the aircraft was at an estimated height of 100 feet above the trees which was higher than on the previous turn in this area and may have resulted from an endeavour to observe each of the two markers in order to line up for the next run. The aircraft commenced a steep descent, with the wings level, consistent with an approach for a seeding run to the east. A few seconds later, when about 250 feet short of the rice paddy, the aircraft struck the sparsely foliated upper branches of a tree which extended about 20 feet above the other trees in the vicinity and the starboard elevator was torn off. With no apparent power reduction, and little change of direction, the aircraft rolled steeply to the left, descended and, after travelling a further 150 feet, struck another tree on the eastern side of the river. The wings and empennage were torn off and the fuselage fell through the tree to the ground and burst into flames.
Probable cause:
The evidence is insufficient for the cause of this accident to be determined but it is evident that the operation was being attempted in such a way as to allow little margin for error in the pilot's judgment of obstruction clearance.
