Circumstances:
The airplane departed Arkhangelsk on a cargo flight to Naryan-Mar with an intermediate stop in Mezen, carrying a load consisting of cans of food for a total weight of 2,5 tons. Approaching the destination, the crew encountered poor weather conditions with snow falls reducing visibility to 800 metres. Unable to establish a radio contact with the destination airport station, the captain asked the copilot to check the radio system. Doing so, the captain was distracted and lost visual references with the horizon. The airplane descended to the ground and crashed in a snow covered field. There were no casualties but the aircraft was destroyed.
Probable cause:
Loss of control on approach after the pilot got distracted and lost his visual cues while discussing with the copilot concerning radio problems. The crew decided to continue the descent to the destination airport despite the airport radio station was unserviceable.

Circumstances:
On final approach to Omsk Airport, in light snow falls, the pilot realized he was not properly aligned with the runway and initiated a go around procedure. Following a short circuit, he started a second attempt to land when, on short final, the airplane rolled to the left and descended to the ground, crashing near the runway threshold. The aircraft was destroyed and all four occupants were killed.
Probable cause:
Loss of control on short final following poor techniques on part of the pilot-in-command. The low visibility caused by snow falls was considered as a contributing factor as well as the fact that the speed indicator was probably showing erroneous parameters because the receptor was obstructed by snow. This situation reduced the aircraft' speed on final, causing a stall.

Approaching Mozdok, he encountered low clouds and decided to return when the airplane collided with a meteo antenna and crashed. The pilot was injured and the aircraft was destroyed.
Probable cause:
The accident was the consequence of the following factors:
- Violation of the published procedures on part of the pilot,
- The pilot modified his route,
- The decision of the pilot to return was taken too late.

Circumstances:
During the day, the pilot already performed twice the flight between Petropavlovsk-Kamchatsky and Ust-Bolsheretsk. After passing over Apacha, weather conditions deteriorated and the visibility dropped to zero due to heavy snow falls. Nevertheless, the pilot attempted to land at Ust-Bolsheretsk and continued the approach when he lost control of the airplane that crashed six km east of the destination airfield. The airplane was destroyed and the pilot was killed.
Probable cause:
The decision of the pilot to initiate an approach in below-minima weather conditions. Lack of discipline on part of the pilot and his failure to return in time were considered as contributing factors.

The aircraft departed Shymkent on a charter flight to Shulakkurgan with two passengers and one pilot on board. A passenger deplaned in Shayan and the second one in Shulakkurgan. In the afternoon, the pilot was flying back ferry to Shymkent. While cruising 45 km south of Shulakkurgan, weather conditions worsened. The airplane entered clouds and the pilot decided to return so he initiated a turn to the right when the airplane impacted the slope of a mountain and crashed. The aircraft was destroyed and the pilot was killed.
Probable cause:
The following factors were identified:
- Lack of discipline on part of the pilot by failing to obey the order given to him upon departure,
- Violation of the Flight Manual on part of the pilot,
- The release of an inexperienced pilot on a charter flight in bad weather,
- The weather bulletin was valid for three hours and thus was not accurate anymore at the time of the accident.

He elected to return to Baku and reduced his altitude when the airplane impacted a hill near Ajikabul. The pilot was injured and the airplane was damaged beyond repair.
Probable cause:
Failure of the pilot to initiate a flight in a visibility that was below the published minimums. The lack of ground visual references was a contributing factor.

Circumstances:
The aircraft departed Sverdlovsk with three passengers on board, three crew members, a load of 257 kg of fret and 38 kg of mail. Few minutes after takeoff, the engine failed. The crew reduced his altitude and attempted an emergency landing when the aircraft crashed in an open field located in Aramil, southeast of Sverdlovsk Airport. All six occupants evacuated safely and the aircraft was damaged beyond repair.
Probable cause:
Engine failure caused by a malfunction of the crankshaft. It was determined that the total weight of the aircraft was 150 kg above MTOW, which caused the failure of the crankshaft because the engine was subject to high contribution.

The decision of the pilot to leave Kokpekty without accurate weather information and later to fly at a too low altitude in poor visibility.

Nevertheless, all surrounding mountains were shrouded in clouds so the pilot decided to return to Tbilisi. While descending through clouds, the pilot lost control of the airplane that dove into the ground and crashed in a wooded area near the airport. Both occupants were seriously injured.
Probable cause:
The crew failed to check the weather conditions prior to departure.
