Approach and Collision
During final approach to Luanda-4 de Fevereiro Airport, the flight crew failed to recognize that the aircraft's altitude was too low. The aircraft subsequently struck a radio antenna located on top of a building. The collision damaged hydraulic and control lines.
Landing and Overrun
After touching down, the aircraft was unable to stop within the remaining runway distance. It overran the runway, lost its nose gear, and came to rest. The aircraft sustained damage beyond repair.
Occupants and Injuries
All nine occupants escaped uninjured.
Probable Cause
According to the official investigation, the aircraft was unable to be stopped within the available distance due to hydraulic problems sustained after the collision with the radio antenna on approach. The probable cause also cites a poor planned approach on the part of the flying crew, who continued the approach below the glide path.
