Circumstances:
The crew was completing a cargo flight from Lobito to Cazombo with an intermediate stop in Luena. On final approach to Cazombo Airport, the crew realized the runway was too short and too narrow when both wings hit bushes upon landing. After touchdown, the crew was informed about the presence of landmines in the airfield and decided to take off immediately. While turning to do so, the right main gear struck a pothole and collapsed, causing the propeller of the engine n°4 to struck the ground. The aircraft came to rest and all six occupants evacuated safely. The aircraft was not repaired.

The crew initiated a turn when the aircraft struck the slope of Mt Arey located few km from Djibouti. The aircraft was destroyed upon impact and all four occupants were killed.
Probable cause:
It is believed that the crew focused on the main gear problems and failed to adhere to standard approach procedure, causing the aircraft to descend prematurely and to struck the mountain. Lack of crew coordination and lack of visibility were considered as contributing factors.

Circumstances:
The aircraft already completed other rotations that day between Bamako and Kano and was returning empty, carrying three Palestinian crew members. En route from Kano to Bamako at dusk, the crew lost his orientation and was unable to report his position. For unknown reasons, he failed to contact Ouagadougou and Niamey ACC. After few dozen minutes, the captain decided to attempt an emergency landing in Dori when the right wing struck a tree and was torn off. Out of control, the aircraft crashed in an open field located few km from Dori Airport. Two occupants were seriously injured while a third crew was killed. The following day, both survivors died from their injuries.
Probable cause:
The crew did not file any flight plan and the accident was the consequence of negligences on part of the crew.

Circumstances:
The four engine aircraft leased from Carib Air Transport to Angola Air Charter was completing a cargo flight from Luanda to Cafunfo, carrying six passengers, four crew members and a load of various goods for the Luanda Norte Province. Shortly after takeoff from runway 24, while climbing to a height of about 50-60 meters, the aircraft banked right then to the left. It stalled and struck the ground on the right side of the runway and disintegrated. All 10 occupants were killed.
Probable cause:
The investigation into the cause of the crash was severely hampered by the fact that the wreckage had been moved from the scene by the orders of an Air Force official, without authorization of the civil aviation authorities (DNAC). Additionally, both flight recorders were not located in the wreckage. The commission found several pieces of debris along the right side of the runway, 300-400 meters from the crash site.
"The accident is deduced to have originated with a probable internal explosion of an unidentified foreign object that perhaps had as its site of action an area of the fuel storage area on the right wing of the aircraft. When the explosion occurred, it would have caused the craft to dip to the right owing to the lack of support on the aerodynamic planes on that side and then to fall to angle of more or less 45 degrees with runway 24 due to asymmetry in the weight of that wing. Greater weight on the [left] side' may have caused the aircraft to stall, because the first impact actually was made by the tip of the left wing striking the ground, prior to the fire that destroyed it totally."
