Circumstances:
The four engine aircraft departed Yuzhno-Sakhalinsk Airport on a cargo flight to Ermolino with two intermediate stops in Ust-Ilimsk and Omsk, carrying 14 passengers, 9 crew members, 8,6 tons of fish, 2 cars and 2 minibuses. The approach to Ust-Ilimsk Airport was completed by night and poor weather conditions (icing conditions) with a visibility below minima due to low clouds. On short final, the aircraft nosed down and crashed on the top of a hill located 2,1 km short of runway. The aircraft was destroyed and all 23 occupants were killed.
Probable cause:
It was determined that the accident was the consequence of a stall caused by an insufficient approach speed. The following contributing factors were reported:
- Poor weather conditions with icing conditions,
- Visibility below minimums,
- The crew failed to follow the approved procedures,
- The approach speed was too low,
- Poor crew coordination,
- Lack of crew interactions,
- The copilot and the navigator did not have sufficient experience,
- The total weight of the aircraft upon departure from Yuzhno-Sakhalinsk Airport was 7,4 tons over MTOW.

Circumstances:
While preparing the flight, the crew encountered technical problems with the engine n°2 and 17 minutes were necessary to start all three engines. A technical issue occurred with the starter of the engine n°2 and a warning light came on in the cockpit. The crew did not find any corrective actions in the operations manual and as he thought the warning was false, decided to take off. Four minutes after the aircraft departed Irkutsk Airport runway 12, while climbing, the starter located in the engine n°2 failed. Debris scattered around and hydraulic and fuel lines were cut. The crew declared an emergency and was cleared for an immediate return after the engine n°2 caught fire. Unfortunately, the crew was unable to extinguish the fire and the aircraft entered an uncontrolled descent and eventually crashed on farm buildings located about 11 km from the airport. The aircraft disintegrated on impact and all 124 occupants were killed as well as one farmer. Another farmer was seriously injured.
Probable cause:
The commission found that the air starter malfunction occurred when the engine was started due to a structural element of the air conditioning system, probably a fragment of the air-to-air radiator (VVR) splitter of engine n°2, hit under the constant pressure flap. This became possible due to the lack of protection against the ingress of foreign objects from the air lines and the low operational reliability of the VVR. A constant supply of air under pressure from the engines operating at a mode close to the nominal through an open damper led to the starter not switching off and the turbine rotor spinning up to off-design speed with the alarm "Dangerous starter speed" being triggered, which was detected by the flight engineer after starting all the engines. Pressing the starter shutdown button did not turn off the alarm. There were no other signs of failure other than the operation of the warning lamp. The crew, believing that the alarm was false, made the wrong decision to take off, which was a consequence of the unwillingness to act in such a situation due to shortcomings in the regulatory documentation, information support, as well as insufficient information content of the starter's technical condition monitoring system in the cockpit. Laying the mains of all three hydraulic systems through the fire-hazardous compartment of the engine n°2 is a constructive disadvantage of the Tu-154M aircraft.

Circumstances:
The four engine aircraft departed Magadan Airport on a cargo flight to Irkutsk, carrying one loadmaster, six crew members and a load of 11 tons of fish. For financial reasons, the crew refused to make a refueling stop at Lensk Airport and decided to continue to Bratsk. Unfortunately, weather conditions worsened at Bratsk and a landing was impossible. In such conditions, the captain decided to continue to Irkutsk and later shut down both engines n°1 and 4 to save fuel. While descending to Irkutsk, both engines n°2 and 3 failed due to fuel exhaustion. The crew reduced his altitude and attempted an emergency landing in an open field located 48 km from Irkutsk Airport. The aircraft belly landed, slid for few dozen metres and eventually came to rest, broken in two. All seven occupants escaped uninjured.
Probable cause:
Engine failure due to fuel exhaustion.

Circumstances:
On final approach to Katanga Airport following an uneventful cargo flight, all four engines stopped simultaneously. The aircraft lost height and struck the ground 1,450 metres short of runway. Upon touchdown, it lost its undercarriage, slid for about 640 metres, struck successively the inner marker and a brick house before coming to rest, broken in two. A passenger was killed while 15 other occupants were injured.
Probable cause:
Failure of all four engines on final approach due to fuel exhaustion. Poor flight planning on part of the crew. At takeoff, the aircraft weight was 7 tons above the MTOW. The crew deliberately decided to load more cargo and less fuel. Investigations determined that the fuel quantity was insufficient for the planned flight.

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.
