What happened
During an en route phase of flight, a twin engine aircraft encountered terrain while operating over the Solomon Islands. The airframe impacted the slope of a mountain located on Vella Lavella Island. The collision resulted in immediate structural failure and impact forces that were unsurvivable for everyone aboard. There were no survivors among the 19 occupants present in the aircraft at the time of the accident.
Findings
The source material does not provide specific technical details regarding mechanical failures, weather conditions, or pilot error. The primary factual conclusion is that the aircraft struck mountainous terrain during its flight path, leading to a fatal outcome for all individuals on board.
