Circumstances:
The crew departed Dnepropetrovskoye, in the suburb of Tselinograd, at 2115LT, on a short flight to a local airport located 12 km from there, following a spraying mission on behalf of the sovkhoz of Dnepropetrovskoye. While flying at a speed of 220 km/h in a relative low altitude, the single engine airplane banked left to an angle of 25° then nosed down and crashed in an open field located 3,5 km from the point of departure, bursting into flames. All three occupants were killed.
Probable cause:
It was determined that the loss of control was the consequence of downdrafts and unpredictable turbulences from a thunderstorm area approaching the accident zone. A poor flight preparation was considered as a contributing factor.

Circumstances:
Following a night takeoff from Almaty Airport, while climbing to a height of 120-150 meters, at a speed of 355 km/h, the airplane entered an area of very high outside temperatures (between +30 and +40° C.). High winds and downdrafts were encountered as well. The airplane nosed down then descended and struck the ground at a speed of 400 km/h some 3,996 meters from the end of the runway. It struck a farm, exploded and crashed. None of the 166 occupants survived the crash and nine people on the ground were injured, three seriously. Debris scattered on 840 meters long and 130 meters wide.
Probable cause:
The accident was the consequence of the impact on the aircraft of an unpredictable, rarely encountered intense atmospheric turbulences area with downdrafts up to 14 meters per second (50 km/h) and a tailwind up to 20 meters per second (72 km/h). The following contributing factors were reported:
- The airplane was operated with a total weight close to the maximum allowable for those conditions,
- The high altitude of the airport,
- A high OAT.

Circumstances:
On a flight from Semipalatinsk to the Semipalatinsk-21 nuclear test site at night when the pilot decided to divert to Chagan because of below-minima weather conditions (snowfall and poor visibility). But the commander of the test site (who was on board) insisted on landing at Semipalatinsk-21. The crew continued the approach but encountered a snow flurry with zero visibility on final approach. Aircraft crashed close to the runway, broke in two parts and caught fire. Two crew were seriously injured while all 7 other occupants were killed.
Probable cause:
Approach continued below minima weather conditions with no visual contact with the runway.

Circumstances:
On final approach to Almaty Airport runway 23, while at an altitude of 400 metres, the left engine caught fire. An explosion occurred and the airplane descended at a speed of 150-190 km/h and crashed in flames in a snow covered field located 3,280 metres short of runway threshold. The aircraft was destroyed and all 90 occupants were killed.
Probable cause:
Failure of a fuel line on the left engine caused the fuel to leak and to ignite while contacting hot air coming from the heating system due to a seal failure. This also resulted in a high carbon monoxide that spread in the cabin and the cockpit. Also, a fuel pump broke away.

Circumstances:
On a night approach to Guryev Airport (now Atyrau), the aircraft passed below the glide path following an error on part of the flying crew and hit the ground at a speed of 210 km/h some 45 meters short of the runway threshold. The aircraft bounced twice and hit the runway surface on a nose down attitude, causing the nose gear to hit the runway with a positive acceleration force of 3,5 g. The aircraft was damaged beyond repair while all 43 occupants were unhurt.
Probable cause:
Wrong approach configuration on part of the pilot-in-command.

Circumstances:
The crew was engaged in a crop spraying mission for the sovkhoz of 'Lenin' located about 45 km from Shardara, south Kazakhstan. The goal of the flight was to spray insecticides on cotton plantations. After takeoff, the engine was not running properly and the crew encountered difficulties to gain sufficient height. The airplane passed over trees at a speed lower than 120 km/h then struck the tops of poplars (30 metres high) located 2,190 metres from the departure point. The airplane stalled and crashed 35 metres further. The captain was killed instantly and the copilot, injured but stuck in the cockpit, asked for help when the engine caught fire about 3-5 minutes later. The aircraft was destroyed by fire and the copilot died.
Probable cause:
Two valves obstructed by calamine caused the engine to lose power and the aircraft to lose speed. The following contributing factors were reported:
- Aircraft usage in a dusty environment,
- High OAT,
- Poor fuel quality.
