Takeoff (climb)

The aircraft was completing a cargo flight from Taiyuan to Riga with intermediate stops in Ürümqi and Baku, carrying seven crew members and a load of clothes. Two minutes after takeoff, while climbing, the aircraft stalled and crashed near a farm located 10 km from the airport. The aircraft was partially destroyed by impact forces and a post crash fire and all seven occupants were killed. Weather conditions were good at the time of the accident with a wind from 170 at 36 km/h.

The aircraft was chartered by a Sudanese Development Unit to deliver medics and other supplies to a school project in Ayod. Shortly after takeoff from Jiech Airport, while in initial climb, the twin engine aircraft stalled and crashed. One pilot and five passengers were killed while four other occupants were injured. Both pilots were New Zealand's citizens. It seems that the cargo shifted after takeoff, causing the aircraft to stall and crash.

Shortly after takeoff from Nampula Airport, while in initial climb, the aircraft went out of control and crashed, killing both occupants. They were engaged in a geological mission on behalf of the Mozambican government in the north part of the country.

The aircraft departed Papeete-Faaa on a local post maintenance flight with one engineer and one pilot on board. Shortly after takeoff, while in initial climb, the pilot informed ATC about control problems and elected to return. Unable to maintain control, he decided to ditch the aircraft few hundred metres offshore. The aircraft sank by a depth of 21 metres and both occupants were able to swim to shore.

A witness at a nearby maintenance facility stated the pilot telephoned him and told him that, during engine start, one engine sputtered and abruptly stopped. The witness stated the pilot told him he wanted to fly the airplane over to have the problem looked at. A witness, who was an airline transport-rated corporate pilot, observed the airplane on takeoff roll and stated the airplane rotated "really late," using approximately 4,000 feet of runway. He stated the airplane climbed to about 400 or 500 feet, then descended in a left spin into the trees. The airplane collided with the ground and caught fire. Examination of the right engine revealed external fire damage and no evidence of mechanical malfunction. Examination of the left engine revealed external fire damage. Disassembly examination of the left engine revealed the rear side of the No. 5 piston from top to bottom was eroded away with characteristics consistent with detonation. The spark plugs displayed "normal" deposits and wear, except the No. 5 bottom plug was contaminated with a fragment of piston ring material, the No. 5 top plug had a dark sooty appearance, and the nose core of the No. 2 bottom plug was fragmented. Flow bench examination of the left fuel servo revealed no abnormalities. The fuel flow manifold diaphragm was heat-damaged. Flow bench examination of the fuel injector lines and nozzles on a serviceable fuel flow manifold revealed the lines and nozzles were free of obstruction. A review of Emergency Operating Procedures for the Aerostar 601P revealed the following: "Normal procedures do not require operation below the single engine minimum control speed, however, should this condition inadvertently arise and engine failure occur, power on the operating engine should immediately be reduced and the nose lowered to attain a speed above ... the single engine minimum control speed."

During a night takeoff from Cairo-Intl Airport runway 23L, the right main gear collapsed. The aircraft went out of control, veered off runway to the right and came to rest few hundred metres further with both right engines n°3 & 4 torn off. All seven occupants escaped uninjured.

The aircraft was operating a scheduled flight starting from its base at Arusha. It was to call at Lake Manyara, Klein’s Camp, Grumet and Seronera before returning to Arusha via Lake Manyara. 5H-MUA took off from Arusha at 0530 hours. It was carrying one pilot and 3 passengers. The VFR flight to Lake Manyara was uneventful and the aircraft landed at Lake Manyara at 0555 hours. Five more passengers joined the flight here and 5H-MUA subsequently took off for Klein’s Camp at 0615 hours. During initial climb, the engine failed. The pilot feathered the propeller and attempted an emergency landing on a road. But he was forced to make an evasive manoeuvre because of a truck. The aircraft lost speed and height, collided with a stone wall beside the road and came tor rest. All nine occupants were rescued, among them five were seriously injured.

The aircraft departed Ankara, Turkey, on a cargo flight to Kabul, Afghanistan, with an intermediate stop in Baku, Azerbaijan. In Ankara, the airplane was loaded with 39,980 kg of cargo. At Baku Airport, 47 tons of fuel were added, bringing the takeoff weight to 189 tons, and the centre of gravity to 29,3% MAC, which was within the prescribed limits. During the eight-hour stopover the crew decided to rest in the aircraft instead of a hotel. As the aircraft started taxiing to the runway the flight engineer was heard saying that he would select the flaps at 30 degrees and slats at 14 degrees for takeoff. This however was not done. Prior to takeoff the position of the flaps was not verified by any of the crew members. Takeoff was thus commenced with flaps and slats retracted and the stabilizer trimmed at the takeoff position -4 degrees (corresponding to actual takeoff weight, CofG and flaps at 30°). At a speed of 210 km/h the pilot pulled on the control column to lift off the nose gear. At a calculated unstick speed of 265 km/h the angle of attack reached 9 degrees but the plane did not lift off the runway. Accelerating through 290 km/h the angle of attack of the aircraft reached 14,5 degrees, setting off the angle of attack warning on the flight deck. Some 1750 meters down the runway, the aft fuselage struck the runway. Seventy meters further on, at a speed of 300 km/h and an angle of attack of 19,4°, the Ilyushin lifted off the runway. The air traffic controller who witnessed the departure advised the crew to abort the takeoff, but the captain apparently continued. The airplane rolled to the left until the wing contacted the runway. Then the flight engineer noted his error and, without informing the captain, began extending the flaps and slats. Again without informing the captain, the flight engineer brought back the power levers of the four engines to idle. After three seconds he moved them from idle to the 'engine shutdown' position. The captain three times yelled "takeoff" but the engines were already shut down. After flying for 490 meters the aircraft struck the ground and crashed.

During the takeoff roll on runway 34 at Jeddah-King Abdulaziz Airport, ATC informed the crew about a fire on the left main gear. The captain rejected takeoff and was able to stop the aircraft within the remaining distance. All 273 occupants evacuated safely but the aircraft was considered as damaged beyond repair.

The twin engine aircraft departed Linz-Hörsching Airport on a taxi flight to Stuttgart with five passengers and two pilots on board. During the takeoff roll on runway 27, at a speed of 105 knots, the crew started the rotation. Immediately after liftoff, the aircraft adopted a high nose attitude with an excessive angle of attack. It rolled to the left, causing the left gear door and the left propeller to struck the runway surface, followed shortly later by the right propeller. After the speed dropped, the aircraft stalled and crash landed on the runway. It slid for few dozen metres and came to rest 2,752 metres past the runway threshold. All seven occupants were evacuated, one passenger suffered serious injuries. The aircraft was damaged beyond repair.
