Circumstances:
The aircraft departed Moscow-Domodedovo Airport on a cargo flight to Komsomolsk-on-Amur with intermediate stops in Omsk and Bratsk, carrying seven crew members and a load of 9,043 kilos of various equipments for the Gagarin Aircraft Manufacturing Plant in Komsomolsk. The aircraft took off from Domodedovo Airport runway 32C at 0415LT. While climbing at a height of about 70-75 metres and a speed of 295 km/h, the aircraft collided with a flock of birds that struck both engines n°3 and 4. Almost simultaneously, both right engines stopped and their respective propeller autofeathered. The aircraft lost speed, rolled to the right to an angle of 45° then entered an uncontrolled descent before crashing a wooded area located 4 km from the airport, bursting into flames. The aircraft was totally destroyed and all 7 occupants were killed.
Probable cause:
Loss of control and subsequent ground impact during initial climb following the failure of both right engines due to a bird strike.

Circumstances:
The aircraft departed Omsk Airport on a test flight to Yakutsk, carrying 22 passengers and a crew of 11 in order to perform a test flight in low-temperature flight conditions, as part of the Ukrainian manufacturer's certification program. During initial climb, at a height of 20 metres, the engine n°3 lost power. The crew increased power on all three other engines and continued to climb. Less than 25 seconds laters, at a height of about 60 metres, the engine n°1 failed. The captain attempted an emergency landing in a snow covered terrain located 660 metres past the runway end. The aircraft belly landed and came to rest with severe damages to the fuselage (almost broke in two at wings level) and engines. All 33 occupants were rescued, among them four were injured, two seriously.
Probable cause:
The loss of power on engine n°3 was the result of the rupture of a hydraulic line located near the rotor. This failure caused a reduction of the blades' rotation on both propellers (counter-rotating system), creating severe vibrations. The crew increased power on all three remaining engines when a technical malfunction occurred on an electric sensor coupled to the turbine of the engine n°1, causing the automatic control unit to fail and the engine n°1 to stop.

Circumstances:
The aircraft was completing a cargo flight from Moscow to Yakutsk with intermediate stops in Omsk and Bratsk, carrying three passengers, seven crew members and a load of 10,990 kilos of various goods (not declared before departure from Moscow). On approach to Omsk-Tsentralny Airport, at an altitude of 1,150 metres, all four engines failed simultaneously. The captain reduced his altitude and made a belly landing in a snow covered field located near Luzino, about 22 km west of the airport. After touchdown, the aircraft slid for few dozen metres, collided with a car and came to rest. All 10 occupants escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Failure of all four engines due to fuel exhaustion. The following contributing factors were reported:
- Poor flight planning,
- The crew failed to calculate the correct amount of fuel necessary for the all flight and reserves according to procedures,
- The captain decided to initiate the descent prematurely, increasing the fuel consumption during the last portion of the flight,
- The flight engineer failed to monitor the fuel consumption during flight,
- Failure of the fuel pump n°5,
- The captain failed to divert to an alternate airport while en route from Moscow to Omsk.

Circumstances:
Following a wrong approach configuration, the twin engine aircraft passed over the runway threshold at a height of 20 meters. At a distance of 300 meters from the runway end, the flight engineer (who was acting as a copilot on this flight) reduced power on both engines above idle. The captain took over control, increased engine power at maximum and initiated a go-around procedure when the left engine autofeathered. At a speed of 170 km/h, the aircraft banked left to an angle of 70° then stalled and crashed 1,526 meters past the runway end. Seven occupants were injured while two others, including one pilot, were killed.
Probable cause:
It was determined that the copilot was intoxicated when he started his duty and was revoked for this flight and replaced by the flight engineer who was in the right seat at the time of the accident. The crew violation of reducing the operating mode of both engines followed by a sudden increase in power resulted in the left engine being automatically feathered. The following contributing factors were reported:
- Poor crew interactions and coordination;
- Errors in landing calculations;
- Poor approach configuration;
- Disproportionate reaction from the captain;
- The replacement of the copilot by the flight engineer due to his incapacity to fly because he was intoxicated.

Circumstances:
Following an uneventful flight from Krasnodar, the crew started the approach to Omsk Airport in a reduced visibility due to the night and rain falls. The aircraft landed at a speed of 270 km/h and about one second later, the captain noticed the presence of vehicles on the runway. He initiated a turn to the right when the left wing struck the vehicles. Upon impact, all three vehicles were destroyed and the four people on board were killed instantly. Out of control, the airplane turned to the left, veered off runway and came to rest upside down, broken in two, bursting into flames. Four crew members and one passenger survived while all 174 other occupants were killed.
Probable cause:
It was determined that the person in charge of the runway maintenance allowed a team of three vehicles to enter the runway for maintenance and then fell asleep. Thus, he failed to inform ATC about the presence of ground vehicles on the runway and the Air Traffic Controller based in the Airport Tower was unable to see the vehicles due to poor visibility caused by night and rain falls. As ATC was not aware of the presence of ground vehicles, he was unable to inform the crew prior to landing. Also, it was reported that the vehicles dispatched on the runway were not equipped with rotating flashing beacons and radios that would allow their personnel to listen the tower frequency.

Circumstances:
Shortly after takeoff from Omsk Airport, while climbing to a height of 10 meters, the pilot-in-command encountered an unexpected situation and reduced the engine power, apparently to attempt an emergency landing. The airplane banked left then stalled and crashed inverted in flames in a field located 128 meters to the left of the runway and about 180 meters past its end. Two passengers and the copilot were seriously injured while 11 other occupants were killed. A day later, both passengers who survived died from their injuries.
Probable cause:
At Omsk Airport, strong winds forced a local technicians team to lock the aircraft rudder while parked on apron. Following negligences on part of the crew, takeoff was initiated with a locked rudder. The following findings were reported:
- The technicians failed to report to the crew that the rudder has been locked by ground personnel,
- The crew failed to follow the pre-takeoff checklist,
- The crew failed to conduct a visual inspection of the airplane prior to takeoff,
- The crew failed to follow the published procedures prior to takeoff,
- The crew failed to proceed to a test of the rudder, ailerons and elevators during the taxi procedure.

Circumstances:
While descending to Omsk Airport, the crew encountered poor weather conditions and low visibility due to snow showers. On final, as he was unable to locate the runway, the captain abandoned the approach and initiated a go-around. Three other attempts to land were abandoned within the next minutes. During the fifth approach, the crew descended too low when the airplane struck a snow wall located just short of runway threshold and crash landed. There were no casualties.
