Technical failure

The aircraft was on its way from Madang to Townsville with an intermediate stop in Port Moresby-Jackson Airport. While cruising over the Coral Sea, a dual engine failure forced the crew to ditch the aircraft some 200 km south of Port Moresby. All 28 occupants took refuge into dinghies and were later rescued. The aircraft sank and was lost.

Following an engine failure in flight, the crew decided to abandon the aircraft and bailed out. The aircraft dove into the ground and crashed. All four crew members were uninjured.

The aircraft left Rockhampton bound for Pitu, Indonesia, with 20 passengers and a crew of two on board. Enroute, the crew decided to return due to insufficient fuel. While approaching Cape Melville, the captain ordered the passengers to bail out. The crew abandoned the aircraft as well and the Dakota crashed into the Bathurst Bay. Five passengers were injured and fifteen others were unhurt. A passenger was killed because his parachute failed to open and no trace of the captain was found.

The crew left Prosnes-A79 AFB to take part to a paratroop exercise involving 42 C-47's. After all paratroopers bailed out, the crew was returning to the base when the right propeller separated from the engine. The pilot lost control of the aircraft that dove into the ground and struck several paratroopers before crashing in a field. All three crew members and six paratroopers were killed.

The twin engine airplane departed Eglin AFB (Valparaiso, Florida), on a flight to Louisville, Kentucky, carrying seven crew members. En route, the pilot encountered engine problems and elected to divert to Wood County Airport when the airplane crashed in a ravine. The airplane was destroyed and all seven occupants were killed.

The crew left Lyon-Bron Airport on a bombing mission to south Germany. Shortly after takeoff, a technical failure forced the crew to attempt an emergency landing but the aircraft crash landed in a field located in Colombier-Saugnieu. Two crew members were killed while four others were injured.

Suffered an engine failure in flight and crashed 10 km southeast of Erhai Lake (Tali Lake), near Dali. Crew fate remains unknown.

Low on fuel while conducting a night training mission in poor weather conditions, the aircraft crashed 2 miles north of Rosedale. A crew members was killed while three others were injured. Sgt. D.J. McLeod parachuted at low altitude and died.
Testimony from the pilot:
The cause of the crash (which the Court of Enquiry called a phenomenon of the weather) was a low cloud bank, right down to the deck, up to about 2000 feet which rolled in from the sea enveloping our base at Bairnsdale, which is near the coast. The 13 aircraft engaged in this night navigation exercise were out at sea. My crash was caused by the lack of fuel. I was the first to take off that night and was about 100 miles from the coast when I sent a signal to base reporting that weather conditions prevented some parts of the navigation procedures being carried out. Base notified all aircraft to return to base. Probably about half of them were able to land at Bairnsdale. After exploring every option available to me the only hope was to bail out because Eastern Victoria was completely covered. So I was about to climb to 5000 feet when we saw a hole in the clouds and a row of lights which could have been a flare path. After checking the fuel and the time we had been in the air I calculated that I still had 30 minutes of fuel which was sufficient to investigate. The lights proved to be a stationary train. I immediately started to climb out when the starboard motor cut at about 2000 feet above sea level. The crew managed to bail out just before the port motor cut. I went into crash landing procedure hitting four trees and losing a large section of one wing and a portion of the other. The aircraft was a write off.
