Investigation Summary
The flight, designated as a training mission for the co-pilot and a logistics transport carrying 12 tonnes of food and supplies, departed Timika at 05:35 local time. As the aircraft approached Wamena, the crew encountered significant weather challenges common to the Papua highlands. At 06:02, the pilot contacted Wamena Tower for a planned landing on Runway 15. Due to deteriorating visibility, the tower suggested a change to Runway 33. Although the tower briefly established visual contact with the Hercules at 06:08, the aircraft disappeared from view and radio contact was lost one minute later. Search and rescue teams located the wreckage on the slopes of Mount Lisuwa, finding the tail section detached and the main body severely burnt. The crash occurred just months after the aircraft had been delivered to Indonesia as part of a purchase of five ex-RAAF C-130H airframes from Australia.
Final Conclusions
The Indonesian Air Force concluded that the crash was a Controlled Flight Into Terrain (CFIT) caused by poor visibility and thick fog. The crew likely suffered spatial disorientation while maneuvering in mountainous terrain under adverse weather conditions. The aircraft was determined to be airworthy at the time of the accident, having undergone routine maintenance checks every 50 hours.
