Narrative:
The Cessna 208 aircraft registered PK-FSO, was being operated on an unscheduled cargo flight from Tanahmerah Airport to Oksibil Airport. On board the aircraft was one pilot, 1,225 kg of general cargo and 800 lbs of fuel.
At 02:44 UTC, in daylight conditions, the aircraft departed Tanahmerah and cruised at altitude of 7,000 feet. Estimate time arrival at Oksibil would be 03:24 UTC.
At 03:12 UTC, when the aircraft position was about 45 NM north of Tanahmerah, the aircraft passed another Cessna 208B aircraft from the opposite direction from Oksibil to Tanahmerah which was cruising at altitude of 6,000 feet.
The pilot failed to contact the the Oksibil air traffic controller and failed to arrive at the destination. The airline's flight following officer received an emergency signal with a last recorded position of 6 NM north of Oksibil.
The next day the aircraft was found on a ridge of Anem Mountain which located about 7 NM north of Oksibil. The aircraft was destroyed by impact forces and the pilot was fatally injured.
