Circumstances:
The crew was involved in a military cargo flight and the aircraft was carrying a load of metallic pipes intended for a pipeline construction. During the takeoff roll, the pilot-in-command encountered an unexpected situation and decided to abort. Unable to stop within the remaining distance, the airplane overran and came to rest in a ditch located 50 meters past the runway end. All six crew members were slightly injured while the aircraft was damaged beyond repair.
Probable cause:
It was determined that prior to takeoff at Tyumen Airport, the crew was instructed to hold for few minutes as an Antonov AN-2 was attempting to land. During this period of time, the crew activated the parking brake and then failed to release it when he was cleared for takeoff. During the takeoff roll, the aircraft was unable to rotate because the parking brake was not released and its speed was insufficient, two factors that were not noticed by the crew in due time.

Circumstances:
The crew departed Khabarovsk-Maly Airport at 1757LT on a local training mission. An hour later, the single engine aircraft went out of control and crashed in flames in a snow covered field located 16 km west of Golubichnoye, in the Amur district. The wreckage was found a day later. Both pilots were killed and the aircraft was destroyed by a post crash fire. It was determined that at an altitude of 800 meters, the airplane descended at a vertical speed of 7 meters per second until the altitude of 200 meters then 21 meters per second until it struck the ground. At impact, the aircraft was in a nose down angle of 25°, 15° left angle and a speed of 250-300 km/h.
Probable cause:
The cause of the accident could not be established, either a fire had emerged in flight or the crew had lost spatial orientation in a snow-flurry.

Circumstances:
On a flight from Milkovo to Khalaktyrka in support of a geological expedition, the crew encountered below-minima weather conditions (visibility limited to 10 km and snowfall). The crew failed to return and deviated from the prescribed flight path to the left by 17 km. The aircraft crashed at a height of 589 metres into the cloud-covered summit of a hill (594 metres) located in Mys Nalycheva, some 45 km northeast of Khalaktyrka. The wreckage was found a day later and all three occupants were killed.
Probable cause:
It was determined that the crew decided to continue the flight despite the deterioration of the weather conditions. The failure of ATC to ask the crew to return to Milkovo or to divert to another airport was considered as a contributing factor, as well as the fact that meteorologists failed to inform the crew about the deterioration of the weather conditions.

Circumstances:
The crew departed Pevek on a special flight to Baranikha in good weather conditions with high clouds and a visibility of 20 km. While approaching Baranikha, weather conditions deteriorated and the visibility dropped to 5 km due to snow falls. While descending to an altitude of 330 meters, the airplane struck a snow covered hill, causing the left ski to be torn off. The airplane continued for dozen yards and eventually nosed down and came to rest in the snow. Both pilots were uninjured while the aircraft was damaged beyond repair.
Probable cause:
Investigations did no reveal any technical anomalies on the aircraft, the engine or any equipment. It is believed the pilot reduced too much the engine power on approach, causing the airplane to lose speed and height.

Circumstances:
An hour after he departed Vorkuta Airport bound for Syktyvkar, the crew reported a fire on the right engine. For undetermined reason, the crew was unable to extinguish the fire and the captain decided to reduce his altitude in an attempt to make an emergency landing. At a height of 100 meters, the right engine detached and out of control, the airplane crashed in flames in an icy pond located near the Bolchaya Vyatkina River. The aircraft was totally destroyed and all 26 occupants were killed.
Probable cause:
The right engine number five cylinder broke in flight, which resulted in the breaking of the connecting rod and the failure of the cylinders number three and seven. The destruction of these three cylinders caused the hydraulic fluid to be ejected from the crankcase through the exhaust manifold, causing a violent fire that the crew was unable to extinguish.

Circumstances:
The departure from Moscow-Sheremetyevo Airport to Conakry and Brazzaville was attempted by night and poor weather conditions. After a course of 1,400 meters, at a speed of 260 km/h, the captain pull up the control column and started the rotation, causing the nose gear to leave the ground. Few seconds later, after a course of 1,850 meters, in a limited visibility, while at a speed of 275 km/h, the left main gear struck a snow wall 60 cm high. Rather than interrupt the takeoff, the captain continued when control was lost. The airplane veered off runway to the right and crashed in flames. Thirteen crew members and eight passengers were killed while 45 other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the crew decided to attempt to takeoff with a visibility limited to 1,000 meters due to fog and snow, which was well below the minima. In such conditions, the aircraft was not properly aligned on the runway centerline, causing the left main gear to struck a snow wall. Investigators believe that Sheremetyevo Airport officials also bear some responsibilities for the accident because they failed to take the appropriate actions to ensure that the runway was properly cleared of snow. At the time of the accident, most elements of the lighting system fitted to both sides of the runway were covered with snow and therefore did not constitute pilot assistance.

Circumstances:
Two hours after his departure from Magadan on a flight to Petropavlovsk-Kamchatsky, while cruising by night at an altitude of 3,600 meters, the crew informed ATC that the right engine failed. The pilot was instructed to divert to Sobolevo Airport for a safe landing but he preferred to continue to the destination despite the fact the aircraft was losing altitude as the power on one engine was insufficient. The aircraft descended to 2,700 meters and the pilot was aware of the mountain en route (2,000 meters high) and estimated his altitude was sufficient (gap of about 600 meters). Few minutes later, weather conditions deteriorated with snow showers and the visibility became very limited. Henceforth at an altitude of 2,000 meters in poor visibility, the airplane struck the slope of Mt Yurshik (2,059 meters high) located about 60 km northwest of Petropavlovsk-Kamchatsky. The wreckage was found three days later, on January 4, and all 23 occupants have been killed.
Probable cause:
In-flight failure of the right engine due to the failure of the cylinder head. The decision of the crew to continue to Petropavlovsk-Kamchatsky instead of diverting to the nearest airport was inappropriate.

Circumstances:
On the leg from Krasnoyarsk to Magadan of a flight from Moscow to Magadan, the autopilot system failed while the aircraft was flying at a height of 8,000 metres by night. The aircraft banked to the left at an angle of 80-90°, entered a dive and descended at a speed of 730 km/h. Control was recovered by the crew at a height of some 4,000 metres. The crew managed to land safely at Magadan-Sokol Airport but the aircraft suffered structural damage during the dive with up to 3.8 g forces. Transferred to the Yegoryevsk technical school on 14DEC66, the aircraft was eventually struck of charge in 16FEB71 due to its poor technical condition. There were no casualties.
Probable cause:
Failure of the autopilot system in flight for undetermined reason.
