Accident
During an approach to Somosomo Airport, the crew encountered poor weather conditions characterized by heavy rainfall and limited visibility. The four-engine aircraft subsequently struck the slope of Mount Tavani, located 18 kilometers from the airport. The impact resulted in three passengers sustaining serious injuries, while 16 other occupants were killed.
Investigation
The investigation into the accident examined the sequence of events leading to the collision. The findings indicated that the aircraft was on approach when it deviated from the intended flight path and impacted terrain at an elevation below the minimum safe altitude for the area.
Probable Cause
According to the official investigation, the probable cause of the accident was that, apparently due to the lack of visibility, the crew started the descent prematurely, causing the aircraft to be too low and to strike the mountain.
