Circumstances:
The crew (one instructor and one pilot under training) departed Blantyre-Chileka Airport on a local training flight. Few minutes after takeoff, the instructor shut down the right engine to simulate a failure and the crew continued the flight when, shortly later, the left engine lost power and failed. The crew elected to restart the right engine but without success. In a such situation, the pilots decided to return to Blantyre Airport when, on final approach, the aircraft stalled and crashed 1,300 meters short of runway. One pilot was killed while the second occupant was seriously injured.
Probable cause:
Failure of the left engine for unknown reasons.

Circumstances:
After takeoff from Juba Airport, while climbing to a height of 300 feet and a speed of 155 knots, the engine n°4 lost power. The crew elected to return for an emergency landing when engine n°1 and 2 oversped. While completing a turn to join the runway 31, the engine n°3 lost power and its propeller was feathered. The crew was able to land the airplane safely but after touchdown, the aircraft was unable to stop within the remaining distance, veered off runway and eventually collided with containers, bursting into flames. All five occupants escaped uninjured.
Probable cause:
The exact cause of the engine problems could not be determined with certainty. However, the assumption that the fuel was contaminated by water was not ruled out.

Circumstances:
During the takeoff roll at Addis Ababa-Bole Airport runway 07, at a speed of about 100 knots, the captain spotted pigeons around the runway and shortly later, the power on engine n°2 and 3 dropped. The crew decided to abort the takeoff maneuver and initiated an emergency braking procedure. Unable to stop within the remaining distance, the aircraft overran, lost its undercarriage, went down an embankment and came to rest, broken in two. All four crew members escaped uninjured while the aircraft was written off.
Probable cause:
It was determined that both engine n°2 and 3 lost power after being hit by a flock of pigeons.

Circumstances:
Following a wrong approach configuration, the twin engine aircraft landed too far down the runway 23 which is 1,600 meters long. After touchdown, the crew realized that the landing distance available was too short and decided to veer off runway. The aircraft rolled on a grassy area and came to rest. All 12 occupants evacuated safely while the aircraft was damaged beyond repair.
Probable cause:
It was determined that the aircraft landed too far down the runway after the crew continued the approach too high on the glide. The braking action was poor because the runway surface was wet which was considered as a contributing factor.

Circumstances:
The aircraft was engaged in a special flight on behalf of the International Committee of the Red Cross (ICRC), carrying 20 passengers and two crew members. During the takeoff roll, the crew encountered directional problems and the aircraft deviated to the right of the runway. The crew was able to takeoff when shortly after liftoff, the right wing struck a mast. The airplane nosed down, struck the ground, lost its nose gear and came to rest in a potatoes field. All 22 occupants were evacuated, among them four passengers suffered minor injuries. One people on the ground was killed.
Probable cause:
It is believed the crew encountered problems with the ailerons and the nosewheel steering system due to hydraulic issues.

Circumstances:
The twin engine aircraft departed Lyon on a flight to Luanda, Angola, with intermediate stops in Algiers, Tamanrasset, Niamey, Port Harcourt and Libreville, carrying five passengers and one pilot. On final approach to Tamanrasset Airport by night, the aircraft stalled and crashed 4,300 meters short of runway 21. The aircraft was destroyed upon impact and all six occupants were killed.
Probable cause:
It was determined that the pilot was on duty since 14 hours without any rest time. He obtained his licence on this aircraft the day prior to the accident and completed a test flight in Brussels before returning to Lyon to start the flight to Angola. Due to lack of experience and intense fatigue, the pilot failed to realize his approach speed was too low, causing the aircraft to stall at a too low altitude to expect recovery.

Four passengers, among them a young girl aged 4 were injured while 20 other occupants were killed.
Probable cause:
Loss of a propeller blade and subsequent loss of control during initial climb.
