Circumstances:
On the leg from Mys Kosistyy to Khatanga of a flight from Pevek to Moscow during the polar night, the aircraft deviated from the prescribed flight path to the left by 38 km. The crew descended prematurely and the twin engine aircraft hit the slope of a hill (340 metres high) located about 65 km from the Khatanga Airport. It came to rest upside down after some 400 metres and caught fire. The rescue teams arrived on the scene a day later, on December 31. A passenger was seriously injured while all 16 other occupants were killed.
Probable cause:
The accident was the consequence of navigation errors on part of the flying crew, which caused the aircraft to deviate from the prescribed flight plan by 38 km to the left. The captain started the descent prematurely, causing the aircraft to struck a hill while flying in limited visibility (8 km) due to the night, clouds and snow falls. The decision of the operations to change the navigator at the last minute may have been a contributing factor due to a possible inoperability between the captain and the navigator. Finally, shortcomings were reported in the polar operations and flight organisation.

Circumstances:
The crew was performing a cargo flight from Kresty Kolymskiye to Mys Kosistyy with an intermediate stop in Chokurdakh. Approaching this airport, weather conditions were poor and the captain decided to divert to the alternate airport of Ust-Yansk located 420 km west of Chokurdakh. On ground at Ust-Yansk, a technical problem was identified on the right engine. After repairs, some tests were made for 1 hour and 10 minutes and as they were conclusive, it was decided to proceed to Mys Kosistyy. En route, while cruising at an altitude of 2,100 meters, the crew encountered technical problems with the right engine due to a loss of hydraulic pressure. The pilot was able to shut the engine down but unfortunately, it was not possible to feather the propeller. Due to high drag, the aircraft was unable to maintain a safe altitude and the crew elected to make an emergency landing. While descending through clouds, the crew encountered icing conditions and the windscreen was covered by ice. In such conditions, the pilot was unable to distinguish the ground when the aircraft crashed in a frozen area located 16 km east of Mys Kosistyy. The wreckage and the six dead bodies were found 16 days later, on November 17, 1948.
Probable cause:
It was determined that the failure of the right engine was caused by a faulty conception of a hydraulic supply vent. Due to a lack of oil pressure, the engine was shot down but the propeller could not be feathered, causing high drag and necessitating an emergency landing. Heavy flight conditions, high drag, night and poor weather conditions, poor operational organisation, absence of a flight plan and the fact that the crew failed to take a 2 hours fuel reserve were considered as contributory factors.

Circumstances:
On landing at Mys Kosistyy, near the Khatanga Bay, when had to go around due to strong cross winds. Engines # 3 and 4 flamed out shortly afterwards so the aircraft stalled and crashed in the tundra some 1,500 meters from the runway. While the aircraft was damaged beyond repair, all six occupants escaped unhurt.
Probable cause:
It appears the flight engineer made a mistake by handling the fuel system, causing both right engines to stop while the captain was attempting a go around.

Circumstances:
Enroute from Mys Kosistyy to Khatanga, the pilot was forced to attempt an emergency landing in the Taymyr Peninsula after the left engine failed. The aircraft crash landed in the tundra about 180 km northwest of Volochanka. The aircraft was damaged beyond repair but all 33 occupants survived the accident. Four days later, as the rescue teams were unable to locate the wreckage, the captain and eight passengers decided to leave the crash site to search for help. On May 11, 1947, the wreckage was eventually spotted and the rescuers arrived on site to evacuate the remaining 24 occupants. Unfortunately, no trace of the pilot and the eight other passengers was ever found. Officially registered CCCP-L1204 in the Soviet Register, the aircraft still have the 42-32892 registration on tail. The wreckage was recovered in 2016 and transferred to as delivered to the Museum of Northern development in Krasnoyarsk.
Probable cause:
Failure of the left engine.
