What happened
During a flight conducted under Visual Flight Rules (VFR), the aircraft collided with a mountain slope in the vicinity of Quetame. At the time of the accident, the flight was operating in poor meteorological conditions. The impact with the terrain resulted in the total destruction of the aircraft and caused 22 fatalities among all individuals on board.
Findings
Investigations into the crash identified that the incident was a case of controlled flight into terrain. This occurred after the crew elected to proceed under VFR despite encountering instrument meteorological conditions (IMC). Several contributing elements were noted, including navigation errors made by the crew during the en route phase and a lack of sufficient training procedures.
