An Indonesian Army Mil Mi-17B-5 en route to a construction site so remote it can only be reached by helicopter was flying from Tarakan to Malinau with a crew of construction workers and a 1,100 pound construction cargo when the helicopter developed engine trouble.
Eight crew and eleven civilian construction workers went down in a jungle in Borneo, thirteen of whom died on impact.
Four passengers and two crew survived. Eight of the fatalities were civilian construction workers, and five were military crew.
The helicopter burned out on the ground near Bulan. The survivors suffered burns.
