A Rimbun Air de Havilland DHC-6-300, registration PK-OTW performing a freight flight from Nabire to Intan Jaya (Indonesia) with 3 crew, had attempted an approach to Intan Jaya's Bilorai Airport [WABV/UGU] in dense fog when the crew initiated a go around at 07:22L (22:22Z Sep 14th). A short time later loud noises of an impact and trees falling was heard at the airport without ever sighting the aircraft. A signal of the emergency locator transmitter activated at that time. Emergency services activated and attempted to find the aircraft, about 2 hours later a helicopter was able to locate the aircraft at an altitude of 2400 meters/7870 feet MSL (Position S3.7433 E136.9873) about 4500 meters/2.4nm from the runway in a "state of total destruction", there were no signs of survivors.

The first officer advised the captain to fly left and they were descending through 8000 feet, the distance was about 2.5nm to the airport. The first officer advised the captain to turn left, subsequently reminded the captain to not to fly too close to the terrain, 14 seconds later the sounds of first impact were recording on the CVR, the CVR stopped 6 seconds after the first sounds.
