The crew departed Uralsk for a local training flight. After completing two slight turns at a height of about 250 metres, the pilot-in-command lost control of the airplane that entered a dive and crashed near the airfield. Both occupants were killed.

Probable cause:

It was determined that the loss of control was the consequence of an aircraft that was not airworthy. After being partially dismantled four months ago, the control column was not properly fixed and the crew decided to make a local training flight. The CofA was not valid anymore since it expired last April 1st. The loss of control occurred at an altitude where the crew was unable to expect recovery.

Probable cause:

The following factors were identified:
- The pilot decided to continue the flight in poor visibility (between 50 and 200 metres) and failed to return,
- Lack of discipline,
- Overconfidence,
- The weather bulletin transmitted to the crew prior to departure from Uralsk were incomplete and inaccurate.

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 Guryev Airport around 1300-1400LT on a flight to Aktyubinsk, carrying one engineer and one pilot, violating several rules. En route, weather conditions worsened and the pilot encountered poor visibility (around 1 km) due to snow falls. While cruising over an oil field, he lost his bearings and failed to locate his position. He initiated a sharp turn to the right, apparently to return, when the airplane impacted ground and crashed. Both occupants were killed.

Probable cause:

The accident was the consequence of a sharp turn at low height in poor weather conditions.
The following contributing factors were identified:
- The pilot was cleared for takeoff despite the weather conditions en route were considered as poor,
- The pilot's licence was expired,
- The CofA was not on board,
- The temporary certificate was late for more than two months.

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.

The pilot escaped with minor injuries and the airplane was destroyed.

Probable cause:

The following contributing factors were identified:
- The pilot adopted wrong piloting techniques,
- Wrong approach calculation and configuration,
- Non compliance with published procedures,
- The pilot landed with a tailwind component,
- The person in charge of the airport failed to change the 'T' according to the wind component.

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.
