What happened
During an approach to Dundo Airport, the crew of the aircraft began their descent earlier than intended. While operating at an altitude of 2,650 feet, the flight encountered heavy fog that significantly restricted visibility. Approximately 50 km from the destination airport, the aircraft type struck a mountain slope. The force of the collision caused the airframe to break apart.
There were seven fatalities among the occupants of the aircraft, with no survivors reported from the crash site.
Findings
Investigation into the accident indicates that the crew initiated the descent prior to reaching the appropriate waypoint. This premature descent resulted in the flight path dropping below the Minimum Descent Altitude (MDA). The combination of descending below the MDA and the presence of dense fog led to the controlled flight into terrain.
