Circumstances:
The crew departed Samarkand Airport at 0615LT to perform a local training program consisting of approaches and touch-and-goes. Eight circuits were completed and during the ninth approach, the instructor decided to shut down the right engine and to feather its propeller. Flaps were selected down to an angle of 38° and the airplane passed over the runway at a height of about 10 meters. Approaching the end of the runway at a speed of 190 km/h, the crew decided to initiate a go-around. Power was added but the airplane went into a nose-up attitude and reached a super critical angle of attack. It turned slightly to the right then descended and crashed in flames 1,120 meters past the runway end. The wreckage was found 690 meters to the right of the extended centerline. The aircraft was partially destroyed by fire and all five crew members were killed.
Probable cause:
It was determined that the loss of control was the consequence of several errors on part of the crew who failed to take appropriate actions to insure that the aircraft's speed was sufficient for a go-around procedure. The crew took too much time (about 10 seconds) to retract flaps and landing gears which prevented the aircraft to have sufficient speed. It was also reported that the training program did not include an engine shut down on approach and that the instructor completed such procedure for the first time, which was considered as a contributing factor.

Circumstances:
18 seconds after it started the takeoff roll, after a distance of 360 meters, while at a speed of 150 km/h, the copilot pointed out a problem with the nose gear and asked if the rudder and elevators were unlocked. At this time, the captain realized that a takeoff was not possible and instructed to abandon the takeoff procedure. Engine power was reduced and an emergency braking procedure was initiated. At this time, the aircraft's was 300 meters from the runway end at a speed of 215 km/h. 18 additional seconds elapsed from the copilot's remark. Unable to stop within the remaining distance, the airplane overran, rolled for 540 meters then collided with an embankment and came to rest in flames against trees. 12 occupants were injured while seven passengers were killed. The aircraft was partially destroyed by a post crash fire.
Probable cause:
It is believed that control column was blocked and a take-off was impossible in such conditions. Various technical investigations could not precisely determine the causes of this anomaly which could be consecutive either to a human error or to the malfunction of the system as a result of the presence of corrosion on connectors, which would affect the alarm of the locking system. The decision to abort the takeoff procedure was taken too late, which was considered as a contributing factor.

He elected to unlock the elevators but the aircraft overran, lost its undercarriage and came to rest in flames. All occupants escaped uninjured while the aircraft was destroyed by fire.
Probable cause:
Poor flight preparation on part of the flying crew who forgot to follow the pre-departure checklist and failed to unlock the elevators prior to takeoff.

Circumstances:
Following an uneventful flight from Tashkent at an altitude of 5,100 meters, the crew was cleared to descent to 2,700 then 2,400 meters. While approaching Samarkand Airport, the crew encountered poor visibility with low clouds. At an altitude of 1,500 meters, in a nose-down attitude of 16° and at a speed of 380 km/h, the airplane struck the slope of a mountain located 32 km northeast of the airport. The copilot and 13 passengers were rescued while 92 other occupants were killed. The aircraft was destroyed upon impact.
Probable cause:
It was determined that the accident was the consequence of the combination of several factors, among them:
- Poor ATC assistance and wrong instructions on part of the approach controller who cleared the crew to descent prematurely as he thought the position of the aircraft was 31 km from airport while it's real position was estimated between 42 and 44 km,
- Lack of visibility due to clouds,
- The flying crew failed to double-check his position after being cleared to descend and continued in clouds.

Circumstances:
On the leg from the sovkhoz (state farm) "Kommunizm" to Samarkand of a flight from Nurata to Samarkand when encountered below-minima weather conditions (low clouds and heavy rain), the captain failed to return (his children were alone at home while his wife was in hospital), he deviated from the prescribed flight path to the East in the pursuit of better weather, flying along the Nuratau mountain range (1,100 metres). Aircraft lost height due to strong katabatic winds and crashed at a height of 930 metres into the slope of a mountain 3.4 km from Shamurat (Nurata district of the Samarkand region). Both pilots and all 9 passengers killed.
Probable cause:
Wrong decision on part of the crew who decided to continue the flight in below-minima weather conditions.

Circumstances:
En route, the crew was informed that weather conditions were poor in Samarkand and received the autorisation to fly directly to Stalinabad. The crew decided to change his route and while flying in cloudy conditions, the pilot in command mistook the Chakchar Mountain Range with the Kush-Tang Mountain Range and started the descent prematurely. At an altitude of 2,600 meters, the right wing hit a rocky peak and the aircraft crashed about 400 meters lower and came to rest at an altitude of 2,270 meters. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 11 occupants was found. On May 8, 1949, the wreckage was found on the slope of Mt Bel'-Aut located in a mountain range of the Surxondaryo province in east Uzbekistan.
Probable cause:
It was determined that the crew cut the route and then followed a wrong track after he mistook two mountain ranges. As the descent was started prematurely, the aircraft was flying at an insufficient altitude at the time of the accident. Poor visibility due to clouds was considered as a contributory factor, as well as wrong decisions on part of the flight operations, lack of discipline on part of the flying crew, lack of organization and communication between the crew and the operations and inappropriate information regarding the weather forecast (information transmitted to the crew had expired).
