Circumstances:
About 20 minutes after takeoff from Abidjan-Port-Bouet Airport, while cruising over the Atlantic Ocean, the fire alarm on engine n°1 sounded. As the fuel temperature was abnormally high, it was decided to shut down the engine. The captain declared an emergency and was cleared to return. On approach, he was cleared to land on runway 03 but preferred to land on runway 21 that was equipped with an ILS system. After completing a back circuit by night but in relative good visibility, the airplane passed over the Abidjan VOR then the pilot-in-command initiated a left turn when the stall warning sounded. While completing a left turn in a flaps and landing gear up configuration, the airplane banked left, stalled and crashed in the forest of Akakro located about 10 km northeast of Abidjan Airport, near the city of Bingerville. A passenger was seriously injured while 50 other occupants were killed.
Probable cause:
It was determined that the fire alarm on engine n°1 also sounded during the first leg from Rio to Abidjan. A check was conducted by Air Afrique technicians who confirmed this was a false alarm. During the last turn completed by a moonless night and without any visual contacts with the ground, the pilot-in-command lost control of the airplane after suffering a spatial disorientation.

Shortly after takeoff from Bata Airport, while climbing, the crew declared an emergency and elected to return. Unfortunately, an emergency landing was not possible as another aircraft was blocking the runway according to ATC. While returning, the crew lost control of the airplane that crashed in the sea few hundred meters offshore. The wreckage was found in shallow water and all 22 occupants were killed. The right engine apparently failed during initial climb and was not functioning at impact.

Circumstances:
The Tupolev 134 departed Mbala (MMQ), Zambia, for a flight back to Maputo (MPM). The flight carried Mozambique president Samora Machel who had attended a meeting of African leaders in Zambia. While approaching Maputo, an inadvertent selection of the MATSAPA VOR frequency caused the crew to execute a premature 37-degrees turn. Although the pilot queried the turn, no effort was made to verify it by using the available navigational aids. The aircraft descended below the 3000 feet limit in spite of not having visual contact with Maputo. The crew erroneously assumed a power failure at Maputo. A 32-second GPWS warning was ignored and the aircraft collided with the ground at 2187 feet, bounced and crashed into an uphill slope. The aircraft broke up, slid across the South African/Eswatini border and caught fire. Machel, along with 33 other occupants did not survive the accident.
Probable cause:
The cause of the accident was that the flight crew failed to follow procedural requirements for an instrument let-down approach , but continued to descend under visual flight rules in darkness and some cloud, i.e. without having visual contact with the ground, below minimum safe altitude, and in addition the ignored GPWS alarm.

Shortly after takeoff from Dakar-Yoff Airport, while in initial climb, white smoke was coming from the engine n°3 while the engine n°4 fire alarm sounded. The engine n°4 was shut down and its propeller was feathered when the aircraft lost height and crashed, bursting into flames. The passenger was seriously injured while all three crew members were killed.
Probable cause:
Engine problems for unknown reasons.

Circumstances:
Following an uneventful flight, the crew started the approach to Pietersburg-Gateway Airport. On descent, the crew encountered poor weather conditions and the visibility was limited. Due to excessive workload in the cockpit, the crew failed to realize his altitude was insufficient when, at an altitude of 5,200 feet, the aircraft struck the slope of a mountain located near Haenertsburg, about 55 km east of Pietersburg Airport. The aircraft was destroyed upon impact and all four occupants were killed.
Probable cause:
It was determined that the crew failed to obtain proper weather bulletin prior to departure. After being stresses by an excessive workload, the crew failed to follow the published procedures and initiated the descente prematurely, causing the aircraft to descend below the minimum prescribed altitude. In consequence, the accident was the result of a controlled flight into terrain.
