Krasnoyarsk Krai

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.

On approach to Turukhansk, the wind was gusting to 43 km/h. Waves up to 50 cm were spotted in the Enisey River. On landing, the seaplane hit three successive waves and plunged into the water. The cockpit separated from the rest of the fuselage, the aircraft came to rest and sank. Three passengers, two women and one child, were killed while 17 other occupants were rescued, five of them seriously injured. The aircraft was a total loss.

Fifteen minutes after takeoff from Krasnoyarsk-Severniy Airport, the oil pressure on the left engine dropped. The crew shut down the engine, feathered the propeller and decided to return to Krasnoyarsk for a safe landing. On final approach, the speed was too high and the crew encountered problems to lower the undercarriage so the captain elected to make a go around. Few minutes later, during a second attempt to land, while at a height of some 50 meters, the aircraft stalled and crashed few hundred yards short of the runway threshold. Eighteen occupants were injured while seven others, among them four crew members, were killed.

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.

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.

Shortly after takeoff from Dudinka Airport, while climbing to a height of 40 meters, the aircraft stalled and crashed on the right embankment of the Yenisei River, about 180 meters from the runway end. The captain V. L. Brekhov was killed while all three other occupants were injured.

After liftoff, while climbing to a height of some 300 meters, the aircraft went out of control and crashed in flames in a field. All ten occupants were killed. It appears that an engine caught fire during the initial climb.

The aircraft was grounded on September 25, 1945, due to technical problems on the right engine, and was ferried for repair to the Osoaviakhim Airfield in Krasnoyarsk where it was used for some unauthorized training flights between 17 and 20 of October. On October 20, on a ferry flight from the Osoaviakhim Airfield to an airfield on the Molokov island located in the Yenisei River for repair (as the repair capacities at the Osoaviakhim Airfield were limited), the right engine caught fire some 3-4 minutes into the flight. Smoke spread in the cabin and the intoxicated pilot decided to return to the Osoaviakhim Airfield but did not manage to do it. The aircraft lost height on final approach, hit a fence and crash landed. The pilot was killed while the flight mechanic as well as the sole (unauthorized) passenger were injured.

Shortly after take off from Krasnoyarsk-Yemilianovo Airport, in initial climb, the aircraft stalled and crashed in flames near the runway end. All twenty occupants were killed.

In the early morning, the crew completed a training flight from Abakan to Ermakovskoye with an intermediate stop in Kuragino. The airplane landed at 1000LT at Ermakovskoye Airfield then departed on a back trip to Abakan. After takeoff, the pilot climbed to a height of 10 metres then made a 180 turn bound to Abakan. While flying at low height some two km from the airfield, the airplane collided with a tall pine, lost height and crashed 150 metres further. The pilot was injured and the cadet was killed.
