While cruising over the Guadalcanal Island, the aircraft hit a mountain slope and crashed. All 15 occupants were killed.

The Dakota left Lae-Nadzab Airport on a medevac flight to Milne Bay carrying 18 patients and 3 Medical Attendants. Whilst over Dobodura, the crew received radio reports that Milne Bay Airfield was not in service, probably due to poor weather conditions. The crew wanted to divert to Port Moresby. En route, the left engine failed. It then appeared that both Jacksons and Wards fields could not be reached due to low ceiling and rain. The airplane then diverted to the emergency airfield on Fisherman's Island. A belly landing was carried out along the strip. There was no fire and all aboard survived.
