Circumstances:
The four engine aircraft departed Yerevan Airport on a cargo flight to Turkmenbashi, carrying 8 passengers, 7 crew members and a load of 13 tons of various goods. En route, while cruising at an altitude of 9,100 metres, the crew requested the permission to divert to Baku-Bina Airport. On approach, the crew was instructed by ATC to initiate a go-around as he was aligned on the wrong runway (a runway under construction and parallel to the active runway 35). The crew started to climb when all four engines stopped simultaneously. The aircraft stalled and crashed in a rocky field located 6 km from the airport. All 15 occupants were injured and the aircraft was destroyed.
Probable cause:
It was determined that the accident was the consequence of the following factors:
- During engine run at Yerevan Airport, the crew encountered technical problems with an engine that could not be started properly, which caused an excessive fuel consumption of 900 litres,
- En route, the crew failed to monitor properly the fuel consumption,
- The decision to divert to Baku-Bina Airport was taken too late,
- The crew failed to declare an emergency and failed to inform ATC that he was short of fuel, which would give him the priority for landing,
- Poor approach planning as the crew was approaching the wrong runway,
- Poor crew coordination,
- The crew failed to raise the landing gear during climbout, which increased fuel consumption.

Circumstances:
En route from Simferopol to Yerevan, while cruising at an altitude of 10,200 meters over the city of Gali in Abkhazia, the crew spotted CB's at high altitude but failed to modify his route. The aircraft went into the CB's and encountered severe turbulences. The crew was able to continue the flight within further incident and to land at Yerevan Airport. After being parked on apron, the aircraft was inspected and it was later confirmed that it sustained severe structural damages after it recorded excessive G loads (+3.05/-0.65). There were no casualties but the aircraft was considered as damaged beyond repair.
Probable cause:
In-flight structural damages caused by severe atmospheric turbulences.

Circumstances:
After completing two round-flights from Tel Aviv to Tehran via Larnaca (Cyprus), the aircraft was returning to Cyprus after having delivered the third tranche of cargo to Iran (a load of tank spare parts and ammunition). On its return flight from Tehran to Cyprus on its third trip, while on a 300° heading to the Turkish border, the crew was instructed to turn left heading 240° direct to Cyprus. For unknown reasons, the plane went off course to the north and crossed the Azerbaijan border without any clearance. Few minutes later, a Soviet Sukhoi Su-15 fighter was dispatched to intercept the CL-44. According to Soviet accounts at that time the crew failed to respond to radio calls as well as signals from the fighter pilot flying close to the CL-44's nose. The cargo plane, while probably making the procedure turn to the left, tried to get away. In unclear circumstances, both aircraft collided. They went out of control and entered a dive before crashing about 50 km from Yerevan. All four crew people on board the CL-44 were killed while the fighter pilot was able to bail out and was found alive. It is unclear whether the collision was intentional, the Soviet pilot said it was a deliberate attempt to down the enemy aircraft, while Western aviation experts examining his account believed he misjudged a turn and subsequently invented a story of self-sacrifice.
Probable cause:
In-flight collision with a Soviet Sukhoi Su-15 fighter in unknown circumstances.

Circumstances:
While cruising by night at an altitude of 7,800 metres, the electrical system failed, causing several instruments to fail, among them gyros. Control was lost and the airplane entered a dive and eventually crashed in a nose-down angle of 70° in an open field located 150 metres from the village of Verkhnyaya Khava, about 50 km northeast of Voronezh. Some debris of the airplane were found at a depth of 14 meters. It disintegrated on impact and all 111 occupants were killed.
Probable cause:
The 36 volts electrical system failed in flight, causing the automatic pilot system to fail as well as instruments such as gyros. Investigations were unable to determine the exact cause of the electrical system's failure. While flying by night and in a visibility reduced by clouds, the crew was unable to have visual references and lost control of the airplane after suffering a spatial disorientation.

Circumstances:
While completing a visual approach to Batumi Airport, the crew encountered poor weather conditions and initiated a go around procedure. The pilot-in-command completed a first turn to the right, flew for about 1,5 km then made a turn to the left. While cruising at an altitude of 550 meters at a speed of about 300-350 km/h in a flaps and gear down configuration, the airplane struck the slope of Mt Mtirala (595 meters high) located 15 km from the airport. The aircraft disintegrated on impact and all 40 occupants have been killed.
Probable cause:
ATC failed to inform the crew about the real weather conditions at Batumi Airport and the crew initiated a go around procedure in marginal weather conditions with a visibility reduced to 3 km instead of the 5 km as mentioned by ATC. In such conditions, the crew was unable to distinguish the mountain, resulting in a controlled flight into terrain.

Circumstances:
The takeoff from Leningrad-Shosseynaya Airport was performed in low clouds and snow falls. After liftoff at a speed of 250 km/h, the airplane climbed to a height of 30-50 meters when it adopted an excessive nose-up attitude and banked left and right. In a high angle of attack, it continued on a distance of 5,300 meters when it lost height, causing the base of the tail to struck the ground. Out of control, it crashed at a speed of 200 km/h in a snow covered field, rolled for about 210 meters and came to rest 290 meters to the right of the extended centerline. Five crew members and a policeman, Major by the Interior Ministry of the Republic of Armenia were killed while 26 other occupants were injured, some of them seriously. 54 other occupants escaped uninjured. The aircraft was destroyed.
Probable cause:
Due to poor flight preparation and lack of coordination, the crew failed to follow the pre-takeoff checklist and failed to deploy the flaps prior to departure, according to the published procedures. It appears that the crew precipitated the takeoff manoeuvre, which was considered as a contributing factor.
