The airplane was engaged in an exercise with a second Sudanese Air Force Antonov AN-32. After touchdown on runway 18, the crew started the braking procedure when the airplane was struck by the AN-32 from behind. After collision, both airplanes went out of control and came to rest on the runway edge. There were no casualties while both aircraft were destroyed. It appears that the AN-32 landed shortly after the AN-26 and was unable to stop in a timely manner.

Crashed on final approach to El Obeid Airport, killing all five crew members. The accident was caused by a technical failure according to the Sudanese Air Force while local rebels claimed they shot down the aircraft with a mortar shell.

The four engine aircraft was performing a flight from Khartoum to Al Fashir with 16 passengers and a crew of six on behalf of the Sudanese National Army. Few minutes after he departed Khartoum-Haj Yusuf Airport, the crew informed ATC about an engine failure and was cleared to return. Few seconds later, a second engine failed on the same side and the crew attempted to make an emergency landing. The aircraft crashed in a desert area located about 22 km from Khartoum Airport. The aircraft disintegrated on impact. 13 occupants were killed while nine other were seriously injured. Few days later, two passengers died from their injuries.

The aircraft was performing a flight from Khartoum to Talodi with a delegation of 26 members of the Sudanese Government, among them several Ministers, Generals and politicians. On approach to Talodi Airport in poor weather conditions due to a sand storm, the crew initiated a go-around procedure when the aircraft impacted the slope of Mt Hagar al Nar (244 metres high) located 1,500 metres south of the airport. The aircraft was destroyed by impact forces and a post crash fire and all 32 occupants were killed.
The official list of the passengers and crew, all of whom died in the crash, is as follows:

Following an uneventful flight from Khartoum, the crew started the descent to Malakal, completed the checklist and lowered the landing gear. A technical problem occurred with the left main gear that remained stuck in its wheel well and failed to deploy. The crew decided to return to Khartoum. On approach to Khartoum-Haj Yusuf Airport runway 18, the crew elected to lower the gear manually but without success. The aircraft landed with both nose and right main gear deployed. After touchdown, the left wing contacted the runway surface. The aircraft slid for about 1,350 metres then veered to the left and came to rest. All 45 occupants evacuated safely and the aircraft was later considered as damaged beyond repair.

The crew started the approach to Zaligei Airport runway 03 in good weather conditions. The aircraft landed hard 200 metres past the runway threshold, causing both propeller blades to struck the ground on a distance of 33 metres. The aircraft bounced and landed a second time 263 metres further then a third time after 15 metres. Upon impact, both engines were torn off and the aircraft rolled for about 400 metres before coming to rest, bursting into flames. Two passengers were killed while five others were injured. All 37 other occupants escaped unhurt. The aircraft was totally destroyed by a post crash fire.

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.

The Antonov 2 aircraft was assigned to spray birds at the white Nile Scheme. The aircraft arrived at Um-galala airstrip 5 days before the accident date and carried out seven spraying flight in the previous five days. The spraying of birds start daily about 18:30 local time and took about 50 minutes flight. According to the scheduled operation the aircraft started its flight ten minutes before Sun set to fly to the assigned bird location for spraying chemicals.On the day of the accident the airstrip lights were positioned by the captain himself at the edges of the airstrip. He put seven lamps at the left side and three lamps at the right side of the airstrip. The red lamp which should have been placed at the beginning of the airstrip was not placed that day due to a flat battery. At about 15:45 UTC the aircraft took-off for spraying birds. That night was dark and there was no moon light. After take-off the technician switched on all lamps except the red one waiting for aircraft arrival. Fifty minutes after take-off the aircraft was seen approaching the airstrip. The aircraft came flying over the strip at a height of about 25 meters and made a left turn. The aircraft then made another approach and came over the left row of lamps at a height of about 10 meters, as stated by the technician, and made a sharp left turn. At that instant the aircraft went down and crashed east of the airstrip. A fire erupted. The pilot died of his injuries. Although the airplane was formally registered ST-AUS in July 2009, the airplane still carried its previous Polish registration mark SP-WMH.

The flight progress strip at Al Fashir aerodrome control tower illustrate that on the 6th of July 2009 – ST-TYB, AN-28 departed Al Fashir at time 0601 UTC, estimated time to arrive destination Sarif-Umra was 0650 UTC, persons on board were two (crew only), intended flight level was 085 (VFR) re-cleared later FL105, fuel endurance was 3,5 hours, load on board as indicated on the cargo manifest was 1511 k.gm (food stuff) destined for the UNAMID forces. Aircraft center of gravity was organized. Calculated actual take off weight was 6335 k.gm and the actual landing weight was 6035 k.gm as reported by the pilot. The aircraft proceeded normally to destination at FL 105, when it reached the airfield, the pilot stated that, they started descend gradually at a speed of 250 km/h willing to check the strip serviceability and to specify the direction of landing from the located wind sock. They detected that, the strip was clear, dry and the wind was favorable to the direction of 23 (strip 23/05). As the crew established a speed of 210 km/h at an altitude of 60 meters on final approach, they saw a dust devil storm on their right crossing the air strip, to avoid this phenomena, they decided to go around for another approach. Eye witnesses confirmed the occurrence of the storm at the time the aircraft commenced the final approach. The crew reported that, they started a right turn and applied full power to gain height, but they felt that there was no response from the engines and the aircraft was influenced by a wind shear and began to sink. The crew managed to control the aircraft, but in few minutes its altitude decreased rapidly. At time 0650 UTC the aircraft impacted with the ground and rolled, there after struck a small rock and bounced, finally the aircraft impacted the ground by the left main gear and nose, and stopped at a distance of 1,850 meters from the beginning of strip 05 coordinates N 13 29.527 ـــــــ E 023 16.794. Crews (2) were safe and the aircraft sustained substantial damage.

The aircraft was cleared for takeoff and began its departure roll with flaps retracted, according to flight data recorder. The aircraft rotated at 280 kph (151 knots) and became airborne at 288 kph (155 knots) at an angle of attack of about 8-9 degrees. Tyre marks on the runway showed, that the aircraft had gone past the end of the runway, the main tyres had impacted runway end lights and the tyre tracks continued past the paved surface of the stopway. Climbing through 15 feet the pilot flying commanded the gear up and increased the pitch angle, the angle of attack increased to more than 10 degrees while the gear doors opened for gear retraction increasing the drag of the aircraft, which began to slow, the speed reduced to 305 kph (164 knots), stall speed for the takeoff weight, and the left wing began to stall, the angle of attack increased to 17 degrees, the aircraft at a height of 5-7 meters/15-23 feet. The pilot flying tried to counteract the roll to the left by fully applying left aileron which also deployed the right wing spoilers, right rudder input was provided. The pilot flying instructed the flight engineer to NOT retract flaps indicative neither pilot was aware the flaps were up. Following that instruction the flight engineer selected the flaps down, the aircraft speed was 300 kph (162 knots) and the aircraft in an unrecoverable stall with no height left. The left hand wing struck a high voltage mast about 1200 meters past the runway end at a height of 5.4 meters (18 feet) shearing off the left wing tip, contacted the flag post at the entrance of the Green Square, the left wing contacted the stem of a tree at a height of about 40 cm (1.3 feet) separating the ailerons and causing fuel spilling from the left wing, the aircraft broke through the eastern brick wall of Green Square, collided with two more electric poles causing engine #4 to separate 1504 meters from the end of the runway and impacted ground at 30 degrees nose down, 30 degrees left bank. Debris was distributed over a length of more than 500 meters, the aircraft burst into flames. All 4 crew perished in the crash, 4 people on the ground received serious, 3 more received minor injuries.
