Circumstances:
The aircraft was performing a cargo flight from Yakutsk to Zyrianka with an intermediate stop at Oymyakon, carrying two passengers, a crew of four and a load of 2,253 kilos of potatoes. While cruising at an altitude of 1,600 meters in clouds, the airplane went out of control, entered a dive and crashed in a wooded area located 95 km west of Oymyakon. The wreckage was found two days later in an isolated area. The aircraft was destroyed and all six occupants have been killed.
Probable cause:
It was determined that the crew failed to follow the procedures in flight and failed to pay attention to the fuel selector that was switched to an empty tank, causing both engines to stop. There was fuel remaining in other tanks but the crew failed to switch the fuel selector in due time. Due to fuel exhaustion, both engines failed and the airplane went out of control while flying in autopilot in clouds.

Circumstances:
The crew was performing a local test flight at Lukhovitsy-Tretyakovo Airport. While completing a third turn on approach, the crew activated the feathering system on the engine number two. Shortly later, while an altitude of 80-100 meters, the airplane banked left, lost height and speed, stalled and struck the ground. On impact, the undercarriage were sheared off and the airplane slid for dozen yards before coming to rest with its left wing broken. All six crew members were unhurt while the aircraft was damaged beyond repair.
Probable cause:
Loss of control on final approach due to loss of thrust on engine number one after the propeller went into autorotation, causing negative thrust.

Circumstances:
On the leg from Kazan to Sverdlovsk-Koltsovo Airport, while cruising at an altitude of 1,200 meters, both engines failed simultaneously. The pilot-in-command reduced his altitude and attempted an emergency landing when the airplane struck trees and crashed in flames in a wooded area located about 120 km west of Sverdlovsk. The wreckage was found the following morning at 0800LT. All five crew members and four passengers were killed while 17 other occupants were injured. The aircraft was destroyed.
Probable cause:
In-flight failure of both engines due to a fuel exhaustion. This was the result of a poor flight preparation on part of the crew who failed to fuel the aircraft with a sufficient quantity prior to departure. It was determined that a total of 1,108 kg of fuel was in the tanks, about 550 kg less than the necessary amount for this routing.

Circumstances:
While cruising at an altitude of 6,100 meters on a flight from Moscow-Vnukovo Airport to Sochi-Adler Airport, the generator on engine number three failed. Debris punctured a hydraulic line and the fluid caught fire while in contact with high temperature elements of the engine. As the fire extinguishing system failed to work properly, the crew decided to shut down all three other engines and completed a gear up landing in a field. The airplane slid for several yards and came to rest. All 97 occupants were evacuated safely.
Probable cause:
Failure of the generator on engine number 3 for unknown reason. This caused the rupture of a hydraulic line and the fluid caught fire while contacting engine elements. The reason of the dysfunction of the fire extinguishing system remains unknown.

Circumstances:
The crew was performing a cargo flight from Irkutsk to Khabarovsk with an intermediate stop in Chita, carrying a load of brake linings and hoses for a total weight of 3,031 kilos. While approaching Chita-Kadala Airport by night, the airplane was too low, struck trees and crashed on the slope of Mt Cherskogo located 11 km short of runway threshold. The wreckage was found 170 meters below the summit and all five crew members were killed.
Probable cause:
For unknown reason, the crew started the descent prematurely and was at an insufficient altitude of 700 meters instead of 1,200 meters when the airplane struck the mountain. Due to the lack of visibility caused by night, the crew was unable to distinguish the mountain. It was also reported that ATC assistance was inappropriate, which was considered as a contributing factor.

While flying at a height of 10 meters after it completed a straight-in path for about 500 meters, the airplane banked left and crashed in a field. The captain was seriously injured and the copilot was killed.
Probable cause:
It was determined that the captain failed to follow the published procedures and committed several errors in flight, causing the airplane to crash. His lack of experience was considered as a contributing factor.

The crew departed Nizhneangarsk Airport at 0843LT on a cargo flight to Dovyren and Irkana, carrying a load of six diesel drums. Twelve minutes later, the crew reported he was climbing to an altitude of 1,200 meters in good weather conditions. About ten minutes later, the single engine airplane crashed in a mountainous area located 7-10 km from Dovyren. As the aircraft failed to arrive at Dovyren, SAR oeprations were conducted and the wreckage was found a day later. Both crew members were killed.
Probable cause:
It was determined that one of the propeller blades failed in flight and struck and broke the windshield. In low visibility caused by snow falls, the crew was unable to attempt an emergency landing as he was flying over a mountainous area. The failure of the propeller blade was caused by a faulty manufacture.

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.
