Papua New Guinea

While descending to Port Moresby Airport, the twin engine aircraft crashed in unknown circumstances 20 miles east of the city. Both crewmen were rescued while the aircraft was damaged beyond repair.

While descending to Bulolo Airport, the twin engine aircraft hit the slope of a mountain and was destroyed. All six occupants were killed.

While cruising at an altitude of 10,500 feet in poor weather conditions, while on a cargo flight from Kerowagi to Lae, the twin engine aircraft hit the rocky face of Mt Kerigomna (3,204 meters high). The wreckage was spotted by another Mandated Airlines crew three days later and the body of the pilot Douglas G. Tapsall, who was killed, was later recovered.

On landing in Port Moresby, the brakes failed. The aircraft overran and came to rest in a ditch. There were no casualties but the aircraft was written off. It was performing a flight from Cape York-Higgins Field (Red Island, Queensland).

Shortly after takeoff, while climbing, the right engine lost power and failed. The pilot made a turn to the left and attempted to make an emergency landing on a beach when the aircraft hit a coconut tree and crashed. The pilot was injured while five other occupants were unhurt. The aircraft was damaged beyond repair.
Testimony from the pilot:
"I drained both fuel tanks for water prior to take-off, but apparently there was still water in one. I had 5 passengers on board. I took off without trouble, but the instant we were off the starboard engine began misfiring, and it lost power fast. Because of the country I commenced a left turn, into the live engine, to try to reach the beach, but I couldn't make it. I put her down on a bit of a clearing in a sacsac swamp. The starboard wing bit a coconut palm and we slewed right around. I banged my head somewhere and got a cut scalp. The passengers were alright though. She burst into flames - was a write-off."
