Narrative Report
On June 30, 2008 at 07:00 AM, Khartoum – Juba experienced a crash involving Ilyushin II-76, operated by Ababeel Aviation, with the event recorded near Khartoum Khartoum (<U+0627><U+0644><U+062E><U+0631><U+0637><U+0648><U+0645>).
The flight was categorized as cargo and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.
4 people were known to be on board, 4 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 4, crew fatalities: 4, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. 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.
