Circumstances:
The aircraft departed Amurzet at 1414LT on a flight to Khabarovsk with an intermediate stop in Birobidzhan, carrying 11 passengers and a crew of two. Weather conditions were considered as marginal with a visibility reduced to 5 km due to rain showers. The crew decided to take off despite the VHF radio communication system was unserviceable. About half an hour into the flight, while cruising at an altitude of 400 meters, weather conditions deteriorated with limited visibility due to mixed rain and snow. The aircraft struck trees and crashed in a wooded area located 15 km north of Bidzhan, bursting into flames. The copilot and four passengers were critically injured while eight other occupants were killed.
Probable cause:
The accident was the consequence of the followings:
- The crew decided to take off while the visibility was below minimums,
- The crew decided to take off while the VHF radio communication was unserviceable,
- The crew failed to inform ATC about the deterioration of the weather conditions,
- When weather conditions deteriorated, the crew failed to return and continued the flight into such conditions,
- The crew modified its route without ATC clearance.

Circumstances:
The airplane was just coming out from the PZL-Mielec factory in Mielec, Poland. Three crew members and one passenger were in charge to deliver the plane to Novosibirsk via Lvov, Samara and Omsk. The crew departed Omsk at noon on the last leg to Novosibirsk and continued in good weather conditions bound to the east. While approaching Tatarsk, weather conditions deteriorated with clouds down to 150 meters above the ground. The pilot-in-command reduced his altitude in an attempt to maintain visual contact with the ground. At an altitude of 199 meters, the single engine airplane struck with its both right wings a relay antenna (202 meters high) located about 5 km northeast of Tatarsk. Out of control, the aircraft lost height and crashed 280 meters further in a snow covered field, bursting into flames. All four occupants were killed.
Probable cause:
The crew failed to prepare the flight properly and took the decision to continue to fly under VFR mode into low clouds with a below-minima visibility. The people in charge to transmit to the crew weather bulletin failed to ensure that information were accurate. A lack of discipline and wrong in-flight decisions on part of the crew were considered as contributing factors.

About half an hour into the flight, the aircraft lost height and descended until it struck trees and crashed in a wooded area located 1,5 km southeast of Kludnevo. Two passengers were injured while four other occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. Technical examination of the engine could not determine if it was running at full power at impact and the assumption that the collector failed in flight was not ruled out.

Circumstances:
The single engine airplane departed Buguruslan Airport at 1332LT on a local training flight, carrying one pilot, one instructor and two cadets. Weather conditions were marginal due to snow falls. After several circuits were completed at an altitude of 700 meters, the crew informed ATC he was descending to 300 meters when control was lost. The airplane lost altitude and crashed in an open field located in Ponikla, bursting into flames. The aircraft was destroyed and all four occupants were killed.
Probable cause:
The exact cause of the accident could not be determined with certainty. However, it was reported that the engine failed en route after it got cold while operated in very low OAT. The lack of crew experience and skills in winter conditions was considered as a contributing factor.

Circumstances:
The aircraft was completing a cargo flight from Sukhumi to Krasnovodsk with intermediate stops in Krasnodar and Rostov-on-Don, carrying 12 passengers (pilots and engineers), four crew members and a load of one ton of mandarins and Christmas trees. Upon departure from Rostov-on-Don Airport, weather conditions were poor due to the night and fog, reducing the vertical visibility to 60 meters and the horizontal visibility to 720 meters. Rotation was made after a course of 750 meters at a speed of 233 km/h. While climbing to a height of 170 meters, at a speed of 320 km/h, the captain requested the flaps to be raised when the aircraft lost height and initiated a descent with a positive acceleration of 1,5 G and with a rate of 5-7 meters per second. In a nose-down attitude and at a speed of 405 km/h, the airplane struck pine trees and crashed in a wooded area located 5 km from the airport, bursting into flames. The accident occurred one minute and 40 seconds after takeoff. The burned wreckage was found 1,180 meters to the left of the approach path. The aircraft was destroyed and all 16 occupants were killed.
Probable cause:
It was determined that the total weight of the aircraft at the time of the accident was 943 kilos above MTOW while the CofG was within limits. Investigations revealed serious shortcomings in the organization and preparation of the flight as well as the training of the various crew members.

Circumstances:
Shortly after takeoff from Ivanovo Airport, while climbing in poor weather conditions, the pilot-in-command lost control of the airplane that stalled and crashed in a field. The crew fate remains unknown while the aircraft was destroyed.
Probable cause:
It was determined that the loss of control occurred during initial climb in poor visibility due to bad weather when the crew failed to prepare the flight according to published procedures and forgot to trigger the artificial horizon.

Circumstances:
The aircraft was chartered by a local hospital in Kyzyl to transfer to Toora-Khem 12 passengers (two patients, four accompanists and a medical team of six crew) and two pilots. After takeoff, the crew was cleared to climb to an altitude of 2,300 meters bound to the north. At 1245LT, the crew reported his position over the mountains and informed ATC about the next point of report. Shortly later, the crew decided to modify his route and to follow a shorter route when weather conditions worsened with poor visibility due to snow falls. While cruising at an altitude of 2,330 meters, the single engine airplane struck a rocky wall of 2,466 meters high. As the airplane failed to arrive at destination, SAR operations were initiated but the wreckage was found five days later, on November 6, about 76 km north of Kyzyl. The aircraft disintegrated on impact and all 14 occupants were killed.
Probable cause:
The decision of the crew to modify his route without permission and to continue in IMC conditions at an insufficient altitude, resulting in a control flight into terrain.
