Circumstances:

During the takeoff roll at Arkhangelsk-Talagi Airport, at a speed of 160 km/h, the captain started the rotation but the airplane failed to rotate. The pilot failed to abort and asked the copilot to detect the reason of the problem when, after a course of 2,250 meters, the airplane overran the runway. It rolled in bushes on a distance of 314 meters then struck the localizer antenna and a small building located 116 meters further. Out of control, the airplane continued on a distance of 55 meters and collided with a concrete pillar before coming to rest in flames. The copilot was killed, the captain and the flight engineer as well as 11 passengers were injured, the others 17 occupants were unhurt. The aircraft was destroyed by impact forces and a post crash fire.

Probable cause:

It was determined that an electrical problem from an unknown source occurred on the elevators locking system, causing the elevators to be jammed during the takeoff procedure. The reaction of the captain was inadequate as he failed to abandon the takeoff manoeuvre when the problem was detected.

Circumstances:

Shortly after takeoff from Semipalatinsk Airport, while climbing to a height of 100 meters, the airplane lots height then struck the ground in a relative flat attitude and crashed in a huge explosion in a snow covered field located 1,457 meters past the runway end. The aircraft was totally destroyed and all 32 occupants were killed, among them 11 female members of the Kyzylorda Basketball Team accompanied by their coach and one judge.

Probable cause:

The exact cause of the accident could not be determined with certainty. Eyewitnesses among them the air traffic controller working in the tower saw a huge flash in the sky prior to the accident. Various analysis did not find any trace of explosives.

Circumstances:

The three engine aircraft departed Irkutsk-Magan Airport at 2229LT bound to the north, cruising at an altitude of 6,000 meters. Weather conditions en route were good. While descending to Bratsk Airport, the crew was informed about the last weather bulletin with no precipitations and a visibility of 50 km. However, during the night approach, weather conditions deteriorated with heavy mixed rain/snow showers and a visibility limited to one km. On short final, the airplane lost height then struck trees and crashed in flames 225 meters further, about 1,250 meters short of runway threshold. The airplane was destroyed by impact forces and a post crash fire and all 18 occupants were killed.

Probable cause:

It was determined that ATC in Bratsk transmitted to the crew a wrong weather bulletin that was referring to weather conditions at 2315LT. Unfortunately, ATC attempted without success to obtain an updated weather briefing and transmitted inaccurate information to the crew. On final, heavy snow/rain showers associated with downdraft and unfavorable winds caused the aircraft to lose height and to crash. The assumption that the crew inadvertently selected the reverse thrust during final approach was not ruled out.

On final approach to Khost Airport, the crew failed to realize his altitude was too low. On short final, the three engine airplane struck tree tops located 154 meters short of runway 24 threshold. After impact, the airplane lost height and landed hard. The crew was able to stop the aircraft normally and as there were no injuries, the aircraft was considered as damaged beyond repair.

Probable cause:

For unknown reason, the crew was approaching the airport at a too low altitude to clear obstacles.
