The crew was engaged in a test flight following modification on the engines by GVF (Grazhdansky Vozdushnyi Flot). The final approach to Vnukovo Airport was completed in low visibility due to foggy conditions, when the aircraft hit a hill and crashed about 10 km northeast of the airport. The occupant fate remains unknown.

The crew was performing a positioning flight from Kimry-Borki to Moscow-Zakharkovo. Few minutes after takeoff, the left engine lost oil pressure and power. The captain elected to make an emergency landing but the aircraft crashed in a wooded area located in Taldom, about 13 km southeast of Borki Airport. The aircraft was destroyed and all five crew members were injured. At the time of the accident, weather conditions were poor with a cloud base at 100 meters and an horizontal visibility limited to two km. It appears that the crew did not receive any permission to complete this positioning flight to Moscow.

The airplane was on a delivery flight from Moscow to Leningrad-Koltushi Airport and has to be transferred from the Soviet Air Force to the Russian Hydro and Meteo Services (Gidrometeosluzhba). Shortly after takeoff, while climbing, the left engine caught fire. The pilot in command elected to make an emergency landing but smoke spread in the cockpit and the crew lost control of the aircraft that crashed in Klyazma. Three crew members, one passenger and one person on the ground were killed while three others were injured (one crew, one passenger and one person on the ground). The aircraft was destroyed.

The crew was engaged in a local training flight in Moscow. While flying at an altitude of 400-450 meters, the crew initiated an engine failure when the aircraft lost speed while performing a steep turn to the left. The aircraft went upside down and crashed in Naberezhnaya, in the suburb of Moscow. All five occupants were killed. It was reported that both passengers were illegal.

One minute after takeoff, while climbing at a height of some 50 metres, the aircraft banked left to an angle of 30°, lost speed and altitude, then hit tree tops and crashed in a wooded area located 3 km from the airport. Four crew members were killed while a fifth crew and the passenger were seriously injured.

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.

On final approach, the visibility was poor due to severe weather and as the aircraft was too low, it hit with its right wing a radio antenna located 2,600 meters short of the runway threshold. The aircraft stalled and crashed in a huge explosion, killing all 22 occupants.

While cruising at an altitude of 1,300 meters en route to Kramatorsk, Ukraine, the left engine failed. Shortly later, the right engine overheated and lost power. In such situation, the pilot attempted to make an emergency landing when the aircraft crash landed onto a hillside. All five occupants were unhurt while the aircraft was damaged beyond repair.

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.
