Circumstances:
On the leg from Urdzhar to Ayaguz of a flight from Urdzhar to Semipalatinsk, the crew encountered below-minima weather conditions (snowfall and poor visibility). The crew failed to return in time and lost orientation so the aircraft crashed at a height of 1,850 metres into the slope of Mt Tikasu (2,151 metres high) located some 30 km from Nekrasovka and caught fire. Both pilots and all 4 passengers were injured and the aircraft was destroyed. The captain left the accident site on 13FEB1968 and reached Nekrasovka after walking through deep snow in mountainous terrain for 18 hours. All other five occupants were rescued and evacuated by the crew of a Mil Mi-4 on 14FEB1968.
Probable cause:
The crew decided to continue in adverse weather conditions and below-minima.

Circumstances:
While on approach to Karaganda Airport, the crew was instructed by ATC to divert to Tselinograd as the airfield was closed to traffic. The pilot ignored this message and decided to continue the descent. After it passed through the last cloud layer, the aircraft was too low and the captain decided to make a go-around when the airplane struck the ground and came to rest 700 meters short of runway threshold. All occupants survived while the aircraft was damaged beyond repair.
Probable cause:
Crew error.

Two crew and 7 passengers were killed while all other 25 occupants were seriously injured.
Probable cause:

Both pilots and all 10 passengers were killed.
Probable cause:

Circumstances:
During take-off roll in poor weather conditions, the engine number 3 failed (probably due to the ingestion of wet snow). The aircraft veered off the snow covered runway to the right after a roll of 550 meters, got briefly airborne with a high angle of attack until the tail struck a 70 cm high mound. Out of control, the aircraft crashed in flames onto a hillside located 1,400 meters further on, by a river. Two passengers and a crew member were killed while all 65 other occupants were injured. The aircraft was destroyed.
Probable cause:
Failure of the engine number three during the takeoff roll due to a massive ingestion of wet snow that was thrown out from the right main gear.

Suddenly, the airplane struck trees, banked right to an angle of 15° the crashed in flames in a snow covered field located 75 meters short of runway threshold. The wreckage was found 600 meters to the right of the extended centerline and the aircraft was destroyed upon impact. Three crew members and 64 passengers were killed while 39 other occupants were injured.
Probable cause:
The crew decided to continue the approach below minima weather conditions by night. The pilot-in-command failed to take the decision to go around. Poor ATC assistance was considered as a contributing factor.

Circumstances:
On the leg from Baiganin to Kenkiyak of a flight from Baiganin to Aktyubinsk, the crew encountered below-minima weather conditions (low clouds and fog), but failed to return to Baiganin and descended instead so that the aircraft crashed at a height of 273 metres into a hill (288 metres) located 18 km southwest of Kenkiyak. The copilot and two passengers were killed. The captain was seriously injured and all other passengers were slightly injured. The aircraft was destroyed.
Probable cause:
It was determined that the crew decided to continue the descent to Kenkiyak in below-minima weather conditions instead of returning to Baiganin. Informations related to weather conditions and transmitted to the crew did not reflect the truth and were considered as too optimistic, which was considered as a contributing factor.

Three minutes after rotation, while at a height of 20 meters, the airplane banked left to a 50-60° angle, plunged into the earth and crashed near the terminal. The airplane was destroyed and the pilot was killed.
Probable cause:
The pilot was dismissed, upon his request, one month prior to the accident and his capabilities and performances were reduced as he was intoxicated at the time of the accident.

After a straight-in flight over few hundred yards at low height, the pilot-in-command made a turn to the right when control was lost. The airplane crashed in a field and came to rest upside down. Both pilots were killed.
Probable cause:
It was determined that the crew failed to prepare the flight properly and did not proceed to a preflight check of the spraying area. However, the exact cause of the loss of control remains unclear.

Few hours later, both passengers, a boy aged 7 and a girl aged 15, died from their injuries. Two days later, the copilot died as well.
Probable cause:
Lack of discipline and rigor on part of the captain who decided to make a steep climb after departure and hazardous maneuvers at low altitude with two passengers on board, which was against the published procedures.
