The aircraft was performing a cargo flight from Timika, carrying five crew members and a load of various goods including constructioin materials. Upon landing on runway 15, the airplane bounced twice. It went out of control and veered off runway to the left. While contacting soft ground, both main landing gear were torn off and the aircraft slid for few dozen metres before coming to rest. All five crew members evacuated safely while the aircraft was damaged beyond repair.

The single engine aircraft departed Wamena Airport at 1100LT with three passengers, two pilots and 508 kg of various goods. About 10 minutes later, the airplane struck the slope of a mountain at an altitude of 2,300 metres. It was scheduled to arrive at Derakma at 1125LT. The wreckage was found a day later by the crew of a helicopter. All five occupants were killed. At the time of the accident, VMC conditions prevailed.

The four engine aircraft departed Timika-Moses Kilangin Airport at 0535LT bound for Wamena. While approaching Wamena, the crew encountered marginal weather conditions and the aircraft descended through several cloud layers when it impaxted a hilly terrain about four minutes before ETA at 0613LT. The aircraft was destroyed by impact forces and a post crash fire and all 13 occupants were killed. The wreckage was found less than 2 km southeast from runway 33 threshold.

On 13 September 2016, a Boeing 737-300 Freighter, registered PK-YSY was being operated by PT. Trigana Air Service on a scheduled cargo flight from Sentani Airport, Jayapura (WAJJ) to Wamena Airport, Wamena (WAVV), Papua, Indonesia. Approximately 2130 UTC, during the flight preparation, the pilot received weather information which stated that on the right base runway 15 of Wamena Airport, on the area of Mount Pikei, low cloud was observed with the cloud base was increasing from 200 to 1000 feet and the visibility was 3 km. At 2145 UTC, the aircraft departed Sentani Airport with flight number IL 7321 and cruised at altitude 18,000 feet. On board the aircraft was two pilots and one Flight Operation Officer (FOO) acted as loadmaster. The aircraft carried 14,913 kg of cargo. The Pilot in Command (PIC) acted as Pilot Flying (PF) while the Second in Command (SIC) acted as Pilot Monitoring (PM). There was no reported or recorded aircraft system abnormality during the flight until the time of occurrence. After passing point MALIO, the aircraft started to descend. The pilot observed the weather met the criteria of Visual Meteorological Condition (VMC). The pilots able to identify another Trigana flight from Sentani to Wamena in front of them. While passing altitude 13,500 feet, approximately over PASS VALLEY, the Wamena Tower controller instructed the pilot to report position over JIWIKA. When the aircraft position was over point JIWIKA, the Wamena Tower controller informed to the pilot that the flight was on sequence number three for landing and instructed the pilot to make orbit over point X, which located at 8 Nm from runway 15. The pilot made two orbits over Point X to make adequate separation with the aircraft ahead prior to received approach clearance. About 7,000 feet (about 2,000 feet above airport elevation), the pilot could not identify visual checkpoint mount PIKEI and attempted to identify a church which was a check point of right base runway 15. The pilot felt that the aircraft position was on right side of runway centerline. About 6,200 feet (about 1,000 feet above airport elevation), the PF reduced the rate of descend and continued the approach. The PM informed to the PF that runway was not in sight and advised to go around. The PF was confident that the aircraft could be landed safely as the aircraft ahead had landed. Approximately 5,600 feet altitude (about 500 feet above airport elevation) and about 2 Nm from runway threshold the PF was able to see the runway and increased the rate of descend. The pilot noticed that the Enhanced Ground Proximity Warning System (EGPWS) aural warning “SINK RATE” active and the PF reduced the rate of descend. While the aircraft passing threshold, the pilot felt the aircraft sunk and touched down at approximately 125 meters from the beginning runway 15. The Flight Data Recorder recorded the vertical acceleration was 3.25 g on touchdown at 2230 UTC. Both of main landings gear collapsed. The left main landing gear detached and found on runway. The engine and lower fuselage contacted to the runway surface. The aircraft veer to the right and stopped approximately 1,890 meters from the beginning of the runway 15. No one was injured on this occurrence and the aircraft had substantially damage. Both pilots and the load master evacuated the aircraft via the forward left main cargo door used a rope.
