Circumstances:
The single engine aircraft departed Yeniseysk in the afternoon on a spraying mission over forest area, carrying two pilots. About 40 minutes into the flight, while completing a third pass at an altitude of about 400 metres, smoke spread in the cockpit. The crew decided to return to Yeniseysk when few minutes later, the engine lost power. Fuel leaked from the engine and spread over the windshield. The crew reduced his altitude to 50 metres and the speed to 85 km/h, preparing for an emergency landing. With the flaps down to 45°, the aircraft collided with trees and crashed in a wooded area located 75 km north of Yeniseysk. Both pilots were slightly injured and the aircraft was damaged beyond repair.
Probable cause:
Loss of engine power due to the failure of the cylinder n°5 caused by a faulty manufacturing.

Circumstances:
The single engine aircraft departed Yeniseysk in good weather conditions on a local geophysical mission over the region of Baykit, carrying two passengers and three crew members. En route, weather conditions deteriorated and the visibility was limited due to low clouds. The crew reduced his altitude to 65 metres to maintain a visual contact with the ground. When facing trees, the pilot-in-command elected to gain height. At a speed of 115 km/h, the aircraft contacted tree tops and crashed in a wooded and hilly terrain. All five occupants were uninjured while the aircraft was damaged beyond repair.
Probable cause:
The crew continued the flight at an unsafe altitude until the aircraft contacted trees and crashed.

Circumstances:
En route from Podkamennaya Tunguska to Yeniseysk, while cruising at an altitude of 1,500 metres, the engine failed. The crew reduced his altitude and attempted an emergency landing when the aircraft struck trees and crashed in a wooded area located near Yartsevo. All 13 occupants were rescued while the aircraft was damaged beyond repair.
Probable cause:
Engine failure in-flight following carburetor icing. It was reported that the airplane has not been prepared for the winter season by the operator's technicians and remained in summer flight conditions. Following a flight of three hours with an OAT of -30° C, the engine failed after the carburetor got iced.

Circumstances:
The airplane was completing a cargo flight to Yeniseysk, carrying six crew members, a passenger in charge of the cargo and a load of 1,042 kilos of sausages, 1,200 kilos of meat, 550 kilos of haring and 2,152 kilos of oranges. The approach was initiated by night and poor weather conditions with limited visibility due to snow falls. On final, approach lights were turned on when the crew saw trees. The captain decided to gain height and increased engine power when the airplane struck trees located on the top of a hill, stalled and crashed in a wooded area located 105 meters to the right of the inner marker and 1,140 meters from the runway threshold. Two crew members were killed while five other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the navigator, the radio operator and the mechanic were intoxicated at the time of the accident. The flight engineer and the navigator failed to follow the approach procedures, probably due to the influence of alcohol. The navigator failed to maintain the calculated rate of descent and altitude, failed to report about what has been achieved in terms of visibility CDF earth landmarks. The mechanic failed to report the airspeed and the altitude in reference of the radio altimeter until 60 meters above the ground. Poor crew coordination and the fact that the captain failed to initiate a go-around procedure were considered as contributing factors.

Circumstances:
The departure from Podkamennaya Tunguska was precipitated (less than 4 minutes between the clearance and the takeoff). After liftoff, while climbing at a height of 8-10 meters, the airplane reached a super critical angle of attack, stalled, banked to the left and crashed 525 meters past the runway end and 77 meters to the left of the extended centerline. The passenger, a company mechanic, was killed while both pilots were seriously injured.
Probable cause:
Wrong takeoff configuration on part of the crew who forgot to put the trim tab of the horizontal stabilizer into neutral position prior to takeoff.

Circumstances:
At 1858LT, a technical issue occurred on the right main gear during the takeoff roll. The captain decided to continue and after rotation, during initial climb, it was not possible to raise the landing gear. The crew informed ATC about his situation and completed several circuits over the region to burn fuel. A bit more than an hour later, the crew returned to Krasnoyarsk-Severny Airport and completed an emergency landing in a grassy area located 100 meters to the right of the main runway. The airplane landed at a speed of 205 km/h. After a course of about 70 meters, the right main gear collapsed and the airplane rolled for few dozen meters before coming to rest in flames. All 53 occupants escaped the cabin but three passengers were seriously injured by fire. Two of the survivors died from their injuries two and three days later.
Probable cause:
Failure of the right main gear due to fatigue cracks in the main cylinder.

Circumstances:
The aircraft departed Norilsk Airport in the late evening of August 23 on a cargo flight (SU22200) to Krasnoyarsk, carrying 10 passengers, a crew of six and a load of cargo consisting of six containers for a total weight of 1,920 kilos. Two hours and 18 minutes into the flight, while cruising by night at an altitude of 7,800 meters, all four engines failed simultaneously due to fuel contamination. The crew declared an emergency and initiated a descent to Yeniseysk Airport. On approach, due to low speed, the airplane lost height then struck tree tops and crashed in flames in a hilly and wooded terrain located 17,9 km short of runway. Five passengers were seriously injured while 11 other occupants, among them all six crew members, were killed.
Probable cause:
It was determined that all four engines failed simultaneously as the fuel was contaminated with water. It was also reported that the refueling system at Norilsk Airport was contaminated with water and that it had not been drained or controlled before being used. Analysis of fuel samples at the crash site showed a concentration of water and sediments between 37% and 88%. Finally, several passengers boarded without valid ticket and only upon captain permission, in violation with published procedures.

Circumstances:
The airplane was completing a cargo flight from Krasnoyarsk to Bajkit with an intermediate stop in Yeniseysk, carrying six passengers, six crew members and a load of 3,700 kg of oranges. On final approach by night, the captain realized his altitude was insufficient and decided to initiate a go-around. He increased power on both engines but followed a wrong path with an insufficient rate of climb. At a speed of 232 km/h, the airplane struck tree tops, stalled and crashed 310 meters further on the slope of a wooded hill (410 meters high) located about 1,700 meters past the end of runway 06. A crew member and three passengers were killed while eight other occupants were injured.
Probable cause:
The captain failed to follow the published procedures related to a go-around maneuver with a too low rate of climb and a wrong path. A poor flight preparation was considered as a contributing factor as well as the fact that the captain was flying to Bajkit for the first time.
