Circumstances:
The twin engine aircraft departed Tabubil and a regular schedule flight to Selbang, carrying 26 passengers and two pilots.

While flying at an altitude of 6,400 feet in clouds, the aircraft struck the slope of a mountain located about 9 km south of Selbang. The aircraft was destroyed and all 28 occupants were killed. At the time of the accident, the cloud layer was reported from 4,000 to 10,000 feet.
Probable cause:

Circumstances:
The twin engine aircraft departed Mount Hagen Airport on a cargo flight to Kamusi, carrying two passengers, one pilot and a load of vegetables. After takeoff, while climbing to a height of about 100 feet, the engine lost power. At a speed of 50 knots, the pilot attempted an emergency landing when the aircraft struck the ground, rolled for about 80 metres and collided with rocks. All three occupants were slightly injured and the aircraft was destroyed.
Probable cause:
No definite conclusion can be reached as to why the aircraft performed so poorly, but from a hypothetical point of view a combination of some of the following could lead to the events that occurred:
1. Substantial inadvertent overload.
2. Mixture excessively rich.
3. Carburettor heat inadvertently selected to hot for takeoff.
4. Aircraft encountered an area of subtle downdraft/downflowing airstream.
5. Propeller controls not set for maximum RPM.

Circumstances:
After takeoff from Bank Airstrip, while climbing in the Simbai Valley, the twin engine aircraft struck the slope of a mountain and crashed about 5,3 km from Bank Airfield. All four occupants were killed.
Probable cause:
The aircraft did not have sufficient power to complete a steep climb as expected by the crew. Apparently, the aircraft stalled while completing a last turn due to an insufficient speed. Poor judgment on part of the crew.

Circumstances:
On approach to Bambu Airstrip (runway 410 metres long), the pilot saw the windsock moving but estimated the wind to be relatively calm. While completing the flare, the aircraft was caught by a sudden updraft and landed too far down the runway. Unable to stop within the remaining distance, it overran and came to rest in bushes. All four occupants escaped uninjured and the aircraft was written off. At the time of the accident, weather conditions were considered as fine with overcast at 8,000 feet and good visibility below clouds. The Bambu runway has a gradient of 9,25% and is very short. Here, the pilot should initiate a go-around procedure as a safe landing was not possible in such conditions.

Circumstances:
After takeoff from Alotau Airport, the pilot followed the published departure procedure for about 17 km when he initiated a turn to the left bound to the northwest, always below clouds. Then, the aircraft entered clouds when, less than two minutes later, it struck the slope of a mountain located some 25 km from Alotau. The aircraft was destroyed and all six occupants were killed.
Probable cause:
Controlled flight into terrain after the pilot was flying under VFR mode in IMC conditions.
