Circumstances:
The four engine aircraft departed Khartoum Airport at 0738LT on a cargo flight to Heglig, carrying four crew members and a load consisting of 13 tons of various goods. On final approach to Heglig Airport, the aircraft was too low. It collided with obstacles and a concrete block located 16 metres short of runway threshold and housing an element of the approach light system. The aircraft bounced, nosed down and landed nose first 52 metres further. After a course of 183 metres, a tyre on the right main gear burst. The captain instructed the flight engineer to activate the reverse thrust systems but the flight engineer did not check the power levers. The aircraft veered off runway to the left, lost its left main gear and came to rest. All four occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration, causing the aircraft to land short of runway.
The following factors were identified:
- The flight engineer unlocked props I, II, III at throttle position < 20 degrees UPRT and No IV engine at 40 degrees UPRT,
- Unrectification of nose wheel and main landing gear crack as recommended by the manufacturer.

Circumstances:
Flight SA8625 departed from Cape Town International Airport on a domestic scheduled flight to George Airport (FAGG) with three crew members and 32 passengers on board. The weather at FAGG was overcast with light rain, and the aircraft was cleared for an instrument landing system approach for runway 11. It touched down between the third and fourth landing marker. According to the air traffic controller, the landing itself appeared normal, but the aircraft did not vacate the runway to the left as it should have. Instead, it veered to the right, overran the runway and rolled on past the ILS localiser. Realising that something was wrong, he activated the crash alarm. The cockpit crew did not broadcast any messages to indicate that they were experiencing a problem. The aircraft collided with eleven approach lights before bursting through the aerodrome perimeter fence and coming to rest in a nose-down attitude on the R404 public road. Several motorists stopped and helped the passengers, who evacuated the aircraft through the service door (right front) and left mid-fuselage emergency exit. The aerodrome fire and rescue personnel arrived within minutes and assisted with the evacuation of the cockpit crew, who were trapped in the cockpit. Ten occupants were admitted to a local hospital for a check-up and released after a few hours. No serious injuries were reported.
Probable cause:
The crew were unable to decelerate the aircraft to a safe stop due to ineffective braking of the aircraft on a wet runway surface, resulting in an overrun.
Contributory factors:
- The aircraft crossed the runway threshold at 50 ft AGL at 143 KIAS, which was 15 kt above the calculated VREF speed.
- Although the aircraft initially touched down within the touchdown zone the transition back into air mode of 1.5 seconds followed by a 4 second delay in applying the brakes after the aircraft remained in permanent ground mode should be considered as a significant contributory factor to this accident as it was imperative to decelerate the aircraft as soon as possible.
- Two of the four main tyres displayed limited to no tyre tread. This was considered to have degraded the displacement of water from the tyre footprint, which had a significant effect on the braking effectiveness of the aircraft during the landing rollout on the wet runway surface.
Several non-compliance procedures were not followed.

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.
