Circumstances:
The crew was completing a flight from Chita to Bratsk with an intermediate stop in Irkutsk. While descending to Bratsk Airport, the crew was instructed to divert to Zheleznogorsk-Ilimski Airport because weather conditions at Bratsk Airport were below minimums. Few minutes later, for unknown reasons, the crew decided to return to Bratsk when the airplane ran out of fuel. The left engine flamed out so the crew attempted an emergency landing on the iced Tareva Bay located on the north shore of the Bratsk Reservoir, about 40 km southwest of Vidim. All six crew members escaped with minor injuries while the aircraft was damaged beyond repair.
Probable cause:
Engine failure caused by a fuel exhaustion.

Circumstances:
En route from Irkutsk to Bratsk, weather conditions worsened with thunderstorms. The crew deviated from the prescribed route when few minutes later, the fuel alarm sounded. The crew attempted an emergency landing when the airplane crash landed in a wooded area. There were no casualties but the aircraft was damaged beyond repair.
Probable cause:
Low fuel conditions forced the crew to attempt an emergency landing. The weather forecast bulletin transmitted to the crew did not reflect the truth and did not mention any thunderstorm activity en route.

Circumstances:
The single engine airplane departed Irkutsk-Magan Airport at 1236LT on a flight to Onguren with an intermediate stop in Kharantsy. At 1303LT, the crew informed ground about his position, flying at an altitude of 1,500 meters. Four minutes later, while cruising in marginal weather conditions, the airplane pitched down and crashed in a nose down attitude of 75° in a wooded area located 15 km east of the village of Kharat. As the radio contact was lost and the airplane failed to arrive at destination, SAR operations were initiated but the wreckage was found a week later only, on September 8, in a hilly and wooded area, at an altitude of 785 meters. The aircraft was totally destroyed and all 13 occupants were killed.
Probable cause:
The exact cause of the accident could not be determined. There were no technical anomalies with the airplane that most probably lost height after being caught by downdrafts coming from a cumulonimbus.

Circumstances:

While cruising by night, the pilot informed ATC that he lost the artificial horizon. Shortly later, control was lost and the airplane entered a dive. It partially disintegrated during the descent and eventually crashed in a pasture. The aircraft was totally destroyed and all seven occupants were killed.
Probable cause:
Failure of the artificial horizon for unknown reasons. The airplane later disintegrated in the air due to aerodynamic forces that exceeded its design and certification.

Circumstances:
The aircraft was engaged in a cargo flight from Ust-Kut to Kirensk, carrying a crew of three, two technicians of the company and two people in charge of the 1,200 kg of cargo. The crew failed to prepare the flight properly, expedited taxi and departure. The airplane took off from runway 30 at a speed of 155 km/h and with an angle of attack of 15°. After rotation, while in initial climb at a height of 120 metres at a speed of 210 km/h, the pilot raised the flaps when the airplane lost height and descended until it struck trees and crashed in flames 1,500 metres past the runway end. The copilot was seriously injured while all six other occupants were killed. Few hours later, the copilot died from his injuries.
Probable cause:
It was determined that the crew precipitated the takeoff procedure and failed to follow the pre-departure checklist. The following contributing factors were reported:
- Poor flight preparation,
- The cabin was not heated prior to departure,
- The left altimeter was erroneously set with a value 10 mm Hg higher than prescribed (wrong altimeter setting),
- Stabilizers were set at -6° instead of the required -3,6° angle,
- The rotation was completed prematurely,
- During initial climb, flaps were raised at a speed of 210-220 km/h, 20 km/h below the speed mentioned in the Flight Manual,
- Lack of visibility,
- Lack of ground visual references.

Circumstances:
The single engine airplane was completing a cargo flight from Karam to Kazashinskoye, carrying two passengers, two pilots and a load of 1,194 kilos of potatoes. While in normal cruise, the crew informed ATC he was diverting to Yukhta for unknown reasons. Few minutes later, while flying in snow falls, the airplane struck trees and crashed in flames on the slope of a mountain located about 63 km north of Kazashinskoye. As the radio contact was lost and the airplane failed to arrive at destination, SAR operations were initiated but eventually suspended after few days as no trace of the aircraft nor the four occupants was found. The crew of an helicopter localized the wreckage on 21 June 1976. It was determined that the airplane struck trees at an altitude of 800 metres, got a little altitude then crashed 60 metres further in a forest. At the time of the accident, the visibility was probably below 2 km and below minimums.
Probable cause:
The decision of the crew to continue the flight in below weather minimums (snow falls) and not returning to his departure point. The accident was the consequence of a controlled flight into terrain.
