Circumstances:
The takeoff from Ufa Airport was completing in marginal weather conditions and the airplane was unable to gain sufficient speed. Despite the situation, the captain decided to rotate and immediately after liftoff, the aircraft adopted a high angle of attack, causing the base of the tail to struck the ground. The aircraft bounced several times then crash landed, overran and came to rest in a garden located 290 meters past the runway end and 220 meters to the left of the extended centerline. The aircraft was destroyed and all four crew members were seriously injured. Five hours after the crash, the captain died from his injuries and 38 hours later, the radio operator died.
Probable cause:
Poor flight preparation on part of the crew who decided to takeoff with a contaminated aircraft. At the time of the accident, the wings, stabs and tail were recovered with an excessive accumulation of snow which reduced drag, limited thrust and performances and modified the aerodynamic.

Circumstances:
After takeoff from runway 27 at Sverdlovsk-Koltsovo Airport, while climbing to a height of 130-150 meters, the right engine failed. This caused severe vibrations and the crew was unable to read the instruments properly. Trying to manipulate the throttle, the flight engineer inadvertently shut down the left engine. Due to a loss of power and insufficient thrust, the airplane lost height and the captain elected to make an emergency landing in a frozen pond located nine km west of the airfield. The aircraft landed at high speed, collided with several obstacles and eventually came to rest, broken in three, after a course of 1,220 meters. Two crew members, three passengers and two people on the ground were killed. 31 occupants were injured and 15 were unhurt. The aircraft was destroyed.
Probable cause:
Due to fatigue cracks, a blade located on the second stage of the compressor failed during initial climb, causing the failure of the right engine and severe vibrations. The inadvertent shut down of the left engine was a contributing factor.

Circumstances:
On final approach, the airplane was not properly aligned and the crew was instructed by ATC to make a go around. For unknown reason, the crew ignored this order and continued the approach. The airplane landed at an excessive speed and was unable to stop within the remaining distance, overran, lost its undercarriage and came to rest in flames. There were no injuries but the aircraft was destroyed.
Probable cause:
Wrong approach configuration on part of the flying crew who failed to make a go around.

Circumstances:
The crew (two pilots, one mechanic and one instructor) departed Stalingrad-Gumrak Airport in the evening to complete a local training mission. Just after liftoff, while in initial climb at a speed of 200 km/h and a height of 20-30 meters, the instructor decided to reduce the engine power to nominal value. The pilot-in-command noticed a loss of power on the left engine and certain that it failed, he ordered the crew to shut it down and to feather its propeller. In the mean time, the airplane banked left to an angle of 70° and then stalled before crashing in a snow covered field located 2,100 meters past the runway end. The mechanic was killed while three other occupants were injured. The aircraft was destroyed.
Probable cause:
It was determined that the instructor decided to reduce the power of the left engine without informing the rest of the crew, which is non compliant to the published procedures. Due to lack of communication, the pilot-in-command interpreted the loss of power for an engine failure. According to procedures, the instructor was not authorized to simulate an engine failure, in fact to reduce the engine power, below the minimum safe altitude of 1,000 meters. Also, his experience on this type of aircraft and in night time conditions was insufficient (176 hours), which was considered as contributing factors, as well as the fact that the captain failed to check his performances.

Circumstances:
The crew departed Stalingrad-Gumrak Airport for a regional meteorological mission. While flying in marginal weather conditions at an altitude of 4,000 meters, the captain decided to climb to 5,200 meters and allowed the rest of the crew to execute non-compliant maneuvers. The aircraft went in stall conditions then entered a dive. The captain elected to regain control but the aircraft crashed in a huge explosion in a snow covered field located in Pervoye Maya, about 85 km northeast of Stalingrad-Gumrak Airport. The aircraft disintegrated in impact and all five crew members were killed.
Probable cause:
Due to insufficient experience, the captain decided to allow the crew to engage in a non-manageable situation that led the aircraft to stall and to crash.

Circumstances:
The crew was completing a training flight from Kuybyshev to Ulyanovsk, carrying 13 crew members (five instructors and eight pilots under supervision) and four employees of the Voronezh aircraft plant. Following an uneventful flight, the pilot started the approach and when the flaps were selected down to 40°, the airplane became unstable. From a height of 120-150 metes, it stalled and crashed in a field located 1,240 meters short of runway threshold. The airplane was destroyed and all 17 occupants were killed.
Probable cause:
The approach was completed in cloud and icing conditions and it is believed that the loss of control was caused by the contamination by ice of critical surfaces such as stabilizers and elevators. The combination of icing conditions and the deployment of the flaps to an angle of 40° caused the aircraft to stall and the distance between the airplane and the ground was insufficient to expect a recovery.

Circumstances:
The aircraft departed Syktyvkar Airport at 2228LT on a flight to Moscow via Gorki and the crew received the permission to climb to 3,000 meters. 18 minutes later, the crew reported icing conditions and received the permission to climb to 3,600 meters. Three minutes later, at 2249LT, the crew reported that the right engine caught fire and requested the permission to divert to the nearest airport. Apparently, the crew was unable to extinguish the fire and the captain completed a rapid descent. After passing the last cloud layer, at an altitude of 100-150 meters, the airplane went out of control and crashed in flames in a field located 500 meters from the village of Chernovo, some 134 km northeast of Gorki Airport. The aircraft was totally destroyed upon impact and all 14 occupants have been killed.
Probable cause:
Failure of the cylinders and pistons on the right engine in flight which caused a fuel and hydraulic leak. Both fluids caught fire when contacted high temperature equipment of the engine. The right engine totalized 1,164 hours and 390 hours since last overhaul.

Circumstances:
The crew departed Leningrad-Shosseynaya Airport at 0947LT for a local training mission. At this time, weather conditions were poor with low clouds down to 200 meters, mist and a visibility less than 5 km. Thus, the crew was instructed to complete the training mission in the vicinity of the airfield. At the beginning of the afternoon, ATC authorized the crew to continue the mission and while cruising at an altitude of 2,100 meters, the pilot-in-command lost control of the airplane that went into a dive. After crossing the last cloud layer, the pilot elected to regain control but it was too late. The airplane crashed and exploded in a field located in Dachnoe, less than a km north of the airfield. The aircraft was totally destroyed and all nine occupants were killed, among them three pilots, four instructors and two passengers.
Probable cause:
The loss of control occurred while the crew was simulating the failure of the right engine in cloudy conditions. Most probably due to successive errors, or maybe due to a spatial disorientation that affected the pilot-in-command, the airplane went out of control and entered a dive. The pilot elected to regain control after passing the last cloud layer (200 meters from the ground) but the distance between the aircraft and the ground was insufficient. The presence of two civilians on board was against the published regulation.

Circumstances:
The aircraft was performing a cargo flight from Magadan to Pevek with intermediate stops at Seymshan, Zyrianka, Nizhni Kresty, and Bilibino, carrying one passenger, a crew of five and two tons of apples. The takeoff was started by night and in snow falls from a contaminated runway. After a long takeoff course, the pilot-in-command completed the rotation at low speed. After liftoff, the airplane reached a high angle of attack, stalled and struck the runway surface several times. It continued for few hundred yards then banked left and eventually crashed in flames in a snowy field located 440 meters past the runway end. The passenger was slightly injured while all five crew members were killed. The aircraft was destroyed.
Probable cause:
The crew took the decision to takeoff from a contaminated runway that has not been properly cleaned prior to the accident. In such conditions, all safety conditions were not met and the aircraft performances were reduced. For undetermined reason, the crew decided to continue the takeoff run despite the course was too long and failed to take the right decision to abandon the departure procedure.

Circumstances:
The crew was performing a cargo flight from Leningrad to Saratov with an intermediate stop at Penza, carrying a load of refrigerator spare parts. After takeoff from Penza Airport, while climbing by night, the airplane banked left to 40° then stalled and crashed in flames in a field located 2 km from the airport. The aircraft was destroyed by impact forces and a post crash fire and all five crew members were killed.
Probable cause:
It was determined that the loss of control during initial climb was caused by an excessive accumulation of ice on both engines and propeller blades. Due to a poor flight preparation and a wrong interpretation of the weather conditions, the captain decided to takeoff in freezing rain. The assumption that all speed indicators, altimeters and variometers were unserviceable at the time of the accident was not ruled out. Also, both engines did not run at impact.
