The aircraft left Almaty Airport at 0515LT bound for Moscow via Balkash, carrying one passenger, five crew members, 763 kilos of various goods and 683 kilos of mail. Upon departure, the total weight of the aircraft was 10,722 kilos, 22 kilos above MTOW. Enroute to Balkash, the crew encountered poor weather conditions. While flying in clouds, some instruments failed. The pilot-in-command lost his orientation and then the control of the aircraft that dove into the ground and crashed in a snow covered area located about 105 km southeast of the Balkash Lake. It was determined that the aircraft hit the ground in a 65° nose-down angle at high speed and disintegrated on impact, causing the debris to be scattered on more than 200 meters. All six occupants were killed.

Probable cause:

Failure of a vacuum regulator which cause the dysfunction of the gyrocompas and then the automatic pilot system. While cruising in very low visibility (night and clouds), the crew suffered a spatial disorientation and lost control of the airplane.

Circumstances:

Six minutes after takeoff from Karaganda Airport, while climbing, the crew reported to ATC that the left engine failed and obtained the permission to return. The pilot in command completed a circuit and started a descent. On final approach, while completing a last turn to the left at a height of 60 meters, the aircraft stalled and crashed in a huge explosion in a field located short of runway threshold. The aircraft was destroyed by impact forces and all 25 occupants were killed.

Probable cause:

Investigations were unable to determine the exact cause of the failure on the left engine. However, it was reported that the crew already encountered technical problems with the same engine a day prior to the accident but failed to report these problems to the ground maintenance.

Circumstances:

Few minutes after its takeoff from Balkhash Airport, while climbing, the aircraft flew into clouds when control was lost. The aircraft banked right and lost altitude. Shortly later, the right wing detached and out of control, the aircraft dove into the ground and crashed in an isolated area located about 39 km northwest of Balkhash. The wreckage was spotted 10 days later, on October 10, and all 15 occupants were killed.

Probable cause:

It was determined that the pilot in command suffered a spatial disorientation while climbing into clouds. Also, the right wing detached presumably because of aerodynamic forces that exceeded its design.

Circumstances:

The pilot departed Karaganda Airport at 0850LT on a mail flight to Balkhash. En route, he encountered thick fog when the airplane impacted the slope of a mountain. The wreckage was found on 8 March 1938 some 20 km southeast of the village of Karataly. The airplane was destroyed and the pilot was killed.

Probable cause:

The accident is the consequence of a controlled flight into terrain after the pilot lost his orientation in fog.
The following contributing factors were identified:
- Poor visibility due to thick fog;
- The pilot decided to continue the flight in such conditions rather than returning to his departure point;
- The airplane impacted terrain at a speed of 350 - 400 km/h.

Circumstances:

The single engine airplane departed Balkash Airport at 1500LT on a schedule service to Karaganda, carrying three passengers, one pilot and mail. En route, weather conditions worsened and the visibility was poor due to snow falls and fog. Instead of returning to Balkhash, the pilot decided to continue. Flying at night, the pilot flew for almost four hours in difficult conditions when the airplane impacted the slope of Mt Kyzyltas located some 190 km north of Balkash, in the region of Aktogay. In the evening, the manager of the Balkhach Airport received a message confirming that the plane landed at Karaganda, which was wrong. It took two days for the Authorities to realize this information was erroneous. The wreckage was eventually found on the slope of the mountain. The aircraft was destroyed and all four occupants were killed.

Probable cause:

The accident was the consequence of a navigation error on part of the pilot who was exhausted after flying nearly seven hours in difficult flying conditions (fog, snowfall, night and rough terrain).
The following contributing factors were identified:
- The aircraft departed Balkhach Airport at 1500LT for a 2 hours and 40 minutes flight, giving an ETA in Karaganda at 1740LT when the sunset was scheduled at 1716LT,
- The aircraft was not certified to fly at night,
- The pilot was only allowed to carry passengers during daylight hours and in good weather conditions only,
- The pilot made the wrong decision by continuing the flight when he should have turned back when he encountered bad weather conditions (fog and snow),
- The pilot was overconfident,
- The pilot obtained weather bulletins for both departure and arrival airports but no information about the conditions en route.

Circumstances:

The airplane departed Alma-Ata on a flight to Balkhash with intermediate stops in Karaganda and Taldykorgan. Following a wrong approach configuration to Balkhash Airport, the pilot led the airplane descending with a crosswind component which caused the airplane to land on one landing gear only. The pilot increased engine power and initiated a go-around procedure. During the circuit, the airplane encountered wind up to 47 km/h and due to inappropriate techniques on part of the pilot-in-command, the aircraft descended to a height of 20 metres. While completing a turn, it stalled and crashed 2 km from the runway, bursting into flames. The aircraft was destroyed and all 10 occupants were killed.

Probable cause:

The immediate cause of the accident was a violation by the pilot of the article 175 of the flight manual, making a turn at a too low altitude on final. It was determined that the pilot was inexperienced on this type of aircraft and that he was dispatched in a solo position while he was not certified for. Investigations revealed that the administration released his solo position the day after the accident.

Circumstances:

The airplane departed Karsakpay at 1330LT on a flight to Dzhusaly, carrying two passengers, one pilot and 39 kg of cargo. The pilot failed to prepare the flight properly, did not get any information about the weather en route and did not have any suitable charts. Few minutes after takeoff, weather conditions deteriorated and the visibility was poor due to snow falls. The pilot decided to return to Karsakpay and initiated a turn when the airplane stalled and crashed in a field located 30 km from Karsakpay. All three occupants were injured, the pilot seriously. He died from his injuries seven days later.

Probable cause:

The accident was the result of a stall during a turn completed at low altitude due to poor piloting techniques with an overloaded aircraft and through difficult weather conditions.
The following factors were identified:
- The pilot started the flight without any information about the flight conditions en route,
- The pilot did not have appropriate maps (charts),
- The pilot was intoxicated the day before and the day of the accident.
