The aircraft departed Surabaya-Juanda Airport in the evening bound for Balikpapan. While in cruising altitude, the airplane disappeared from radar screens and crashed into the Java Sea. SAR were conducted but eventually suspended after few days as no trace of the aircraft nor the 26 occupants was found. The crew was unable to send any distress call prior to the accident.

Crashed into the sea off Sumatra Island apparently after being shot down by the pilot of a Dutch Air Force fighter.

Crashed whilst escorting a Catalina to an area near the southern tip of Borneo. As the Catalina landed and sent a party ashore to talk with the natives, the captain circled the area then left but flew too low and did not pullout of a shallow dive in time . The aircraft struck a coconut tree sending it crashing into the ground. It was only later that the Catalina crew were advised the Mitchell had crashed and proceeded to the area where the Mitchell had gone down and discovered two survivors. One of them died from his injuries few hours later.

The aircraft was on its way from Australia to Biak with an intermediate stop in Merauke. On board were three passengers returning from leave, four crew members and cargo consisting of fresh food. While cruising at an altitude of 12,000 feet in intermittent rains, the airplane hit the slope of a rocky mountain located in the Sudirman mountains. As the aircraft failed to arrive, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. A New Zealander explorer found the wreckage on March 2, 1962.

The crew was involved in a special paratroop mission over Indonesia. As the aircraft was never found, it is believed it crashed into the sea off Borneo.

En route, the crew was informed by ground about the deterioration of the weather conditions. Shortly later, the twin engine aircraft crashed in unknown circumstances somewhere in Iran Jaya. All six occupants were killed.
