Circumstances:

The aircraft was completing flight UNO-052P from Bamako to Gao on behalf of the United Nations Multidimensional Integrated Stabilization Mission in Mali (MINUSMA). En route, the crew encountered technical problems with the electrical system when the right generator failed. The crew attempted to start the APU several times but without success when the left generator also failed. The undercarriage were lowered manually and the landing was completed on a wet runway in rainy conditions. After touchdown, 500 metres past the runway threshold, the crew started the braking procedure but was unable to deploy the thrust reversers. At a speed of 140-160 km/h, the aircraft overran, lost its undercarriage and came to rest in a waterlogged land. All 11 occupants were rescued, among them six were injured. The aircraft was destroyed.

Probable cause:

The aviation incident occurred during rollout after landing, resulting in the longitudinal excursion of the aircraft beyond the runway and collision with a sewage collector during ground movement. The landing was performed on a fully unpowered aircraft with wing flaps retracted, without the possibility of using spoilers and engine reversers for braking. Immediately after landing, the wheel brake system failed due to its usage by the crew at speeds significantly exceeding the established FCOM maximum values for the An-74TK-100 aircraft. The landing under these conditions exceeded the expected operating conditions, as there is no data in the FCOM for its calculation and execution.
The most probable contributing factors were:
- The absence of information in the FCOM regarding landing calculation and crew actions during unpowered flight (landing with retracted flaps without the possibility of using spoilers and engine reversers) due to the aircraft developer's assessment of such a situation as practically improbable.
- Poor execution of pre-flight refueling of generator oil systems and a lack of proper control over their execution, leading to exceeding the permissible maximum oil level, its overheating in flight, melting of thermal sensors, and sequential automatic disconnection of two GP21 generators.
- Failure of the crew to adhere to standard operational procedures for the APU in-flight (failure to activate the APU compartment heater), as well as the preparation and start-up methods outlined in the FCOM, leading to the inability to start the APU and complete loss of power in the aircraft after the battery voltage dropped below the permissible value.

Following an uneventful cloud seeding mission over the region of Mopti, the pilot was returning to Bamako-Senou Airport. For unknown reasons, the aircraft made a belly landing and slid for few dozen metres before coming to rest on the right side of runway 06/24. The pilot escaped uninjured and the aircraft was damaged beyond repair.

Circumstances:

Before take off at Nouakchott, two fuel trucks arrived to the airplane but captain declined and calculated that the reserve he has was sufficient to fly to Bamako. While approaching Bamako, right engine failed due to fuel exhaustion, followed by the left engine five minutes later. Crew elected to divert to Kolokani, a small airstrip located 19 km from Bamako. Eventually, crew was forced to make an emergency landing off airport. On landing, aircraft lost its undercarriage while the right wing was sheared off. All nine occupants were uninjured while the aircraft was destroyed. Flight was performed on behalf of the 524th Special Operations Squadron, for the USAF and Africom, a military mission in Africa.

Probable cause:

The Accident Investigation Board (AIB) President found by clear and convincing evidence that the cause of this mishap was the mishap aircraft running out of fuel due to the mishap aircraft commander’s and mishap copilot’s failure to properly fuel plan and then refuel the mishap aircraft at Nouakchott with a sufficient amount to reach their destination. Once airborne, despite indications of a fuel shortage, the mishap crew did not divert to a suitable alternate airport early enough in the sortie to avoid this mishap. The AIB President also found sufficient evidence to conclude the following factors substantially contributed to the mishap: insufficient mission and flight planning; faulty decision-making; complacency; task misprioritization; channelized attention; and the mishap crew pressing to meet mission demands.

Circumstances:

While descending to Bamako-Senou Airport, the crew was informed about the poor weather conditions at destination with thunderstorm activity and strong crosswinds. As the visibility was estimated to be above 10 km, the crew decided to continue the approach. After landing on runway 06, the aircraft was caught by strong crosswinds and started to roll left and right, causing the right wing to struck the runway surface. Out of control, the aircraft veered off runway to the right and collided with a bunker. The right wing was torn off and the aircraft came to rest. All four crew members escaped uninjured.

Probable cause:

Loss of control after landing due to strong crosswinds in thunderstorm activity.

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.
