Circumstances:
On a flight from Baku to Aktau in difficult weather conditions at night when took off with caged gyro horizons, so the crew lost spatial orientation. The aircraft entered a steep right downward spiral and crashed on the shore of the Caspian Sea near Nardaran, some 35 km northeast of Baku, less than five minutes after takeoff. All 5 crew and 18 passengers were killed, among them were 15 Azeris, one Briton, one Australian, one Turkish, one Georgian and 4 Kazakh.
Probable cause:
The gyro horizons failed after takeoff due to a malfunction caused by the fact that some counterfeit assemblies and instruments had been installed by KhGAPP during the production of the aircraft. While cruising at night and poor visibility, the crew lost situational awareness and suffered a spatial disorientation, causing the aircraft to enter an uncontrolled descent and to crash into the sea. The lack of visual references on ground was considered as a contributing factor.

Circumstances:
The aircraft departed Ankara, Turkey, on a cargo flight to Kabul, Afghanistan, with an intermediate stop in Baku, Azerbaijan. In Ankara, the airplane was loaded with 39,980 kg of cargo. At Baku Airport, 47 tons of fuel were added, bringing the takeoff weight to 189 tons, and the centre of gravity to 29,3% MAC, which was within the prescribed limits. During the eight-hour stopover the crew decided to rest in the aircraft instead of a hotel. As the aircraft started taxiing to the runway the flight engineer was heard saying that he would select the flaps at 30 degrees and slats at 14 degrees for takeoff. This however was not done. Prior to takeoff the position of the flaps was not verified by any of the crew members. Takeoff was thus commenced with flaps and slats retracted and the stabilizer trimmed at the takeoff position -4 degrees (corresponding to actual takeoff weight, CofG and flaps at 30°). At a speed of 210 km/h the pilot pulled on the control column to lift off the nose gear. At a calculated unstick speed of 265 km/h the angle of attack reached 9 degrees but the plane did not lift off the runway. Accelerating through 290 km/h the angle of attack of the aircraft reached 14,5 degrees, setting off the angle of attack warning on the flight deck. Some 1750 meters down the runway, the aft fuselage struck the runway. Seventy meters further on, at a speed of 300 km/h and an angle of attack of 19,4°, the Ilyushin lifted off the runway. The air traffic controller who witnessed the departure advised the crew to abort the takeoff, but the captain apparently continued. The airplane rolled to the left until the wing contacted the runway. Then the flight engineer noted his error and, without informing the captain, began extending the flaps and slats. Again without informing the captain, the flight engineer brought back the power levers of the four engines to idle. After three seconds he moved them from idle to the 'engine shutdown' position. The captain three times yelled "takeoff" but the engines were already shut down. After flying for 490 meters the aircraft struck the ground and crashed.
Probable cause:
Failure of the flight engineer to extend flaps and slats prior to takeoff. The following contributing factors were identified:
- Poor crew coordination,
- Poor flight preparation,
- Crew fatigue.

Circumstances:
The crew was completing a local training flight at Gyandzha Airport and already performed three full stops and one touch-and-go manoeuvre. After completing a circuit, the crew was attempting a new approach when the aircraft nosed down to an angle of 70° and crashed 5,160 metres short of runway and 93 metres to the left of its extended centerline. The aircraft disintegrated on impact and all six crew members were killed.
Probable cause:
It was determined that a group of Azeri soldiers returning along the highway from the range to the barracks wanted to have fun and were shooting on road signs. When they saw the airplane, they shot towards it and two bullets punched oxygen bottles which exploded, causing a fire and intoxicating the pilots who lost control of the airplane.

Circumstances:
During initial climb, at a height of about 60 metres and at a speed of 317 km/h, the left engine failed. The copilot counteracted the left bank and five seconds later, the flight engineer informed the crew that the right engine also failed. The captain took over control and the aircraft climbed to the height of 197 metres when the speed dropped to 290 km/h. The captain elected to make an emergency landing but was forced to make a sharp turn to the right to avoid a building. The aircraft rolled to the right to an angle of 37° and adopted a rate of descent of 1,960 feet per minute before crashing in an open field located 3,850 metres from the airport. The aircraft disintegrated on impact. Thirty occupants were rescued while 52 others, among them two crew members, were killed.
Probable cause:
It was determined that the left engine failed during initial climb following the disintegration of the 2nd and 3rd stage of the compressor. Investigations revealed that the maintenance was non compliant and that 38 screws were missing on the main compressor, a violation that was not repaired during the last maintenance inspection conducted 30 flying hours prior to the accident. Following a lack of crew coordination but also a faulty ergonomy of the flight deck, the flight engineer mistakenly shut down the right engine that was running properly.

Circumstances:
After takeoff from Ürümqi Airport, while on a cargo flight to Baku, the crew encountered technical problems with the left main gear that remained down. The crew decided to continue to Baku in such configuration. On approach to Baku-Bina Airport by night, the captain contacted ATC and was cleared to proceed to a low pass to check the undercarriage. Following the low pass, the crew initiated a turn to the left and followed a circuit for a second approach. While flying at a relative low altitude, all four engines suffered a loss of power. The aircraft lost height, collided with light poles on a bridge and crashed in a field located 9 km from the airport. Four crew members were seriously injured and two others were killed.
Probable cause:
It was determined that all four engines lost power due to low fuel. The following contributing factors were reported:
- A malfunction of the landing gear retraction system, which led to fly with a landing gear extended and caused an excessive fuel consumption. The subsequent failure to lock the left landing gear in the extended position made it necessary to do a second approach with a limited amount of fuel.
- The fuel gauge indicator readings were inaccurate and prevented the crew from having correct info about the amount of fuel available and applying the flight manual's recommendations for low-fuel flights.
- The lack of an airline bulletin on the features of the fuel system prevented the crew in the emergency situation from selecting the optimum mode for flying with a limited amount of fuel.
- Inadequate operational and maintenance organization on the part of the companies Baku Air and ALG Inc.

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:
The aircraft operated on a passenger service from Yerevan-Erebuni Airport to Stepanakert Airport. In addition to 30 passengers with tickets, the crew took on board 13 unregistered passengers. With this heavy load, the captain requested a lower altitude, 4,500 meters, for the flight. This was granted by ATC, while the regular altitude on the route was 5,100-6,600 meters with a minimum safe height of 4,516 meters. At 09:59, at a distance of 21 km after passing the Azizbekov NDB, the crew was taken over by a controller of Kafan Airport. The controller instructed to keep the height of 4,500 meters to the point of descent. The flight was the cleared down to 3,900 meters and the aircraft descended over mountains covered by a cloud deck with an upper boundary of 3,000-3,300 meters. However, the flight crew never reported their exact position and the controller did not check it on radar. The flight reached the altitude of 3,900 meters at 10:07, and continued descending without informing the controller. At 10:08, the captain requested to contact Stepanakert, while giving a false report that the flight altitude was 3,900 meters. Not observing the aircraft, not knowing its actual flight altitude and not having direct communication with the controller at Stepanakert, the Kafan ATC controller allowed the crew to switch to the Stepanakert frequency. The captain reported to the controller that they were at an altitude of 3,900 meters and requested permission to descend to 2,400 meters. The controller at Stepanakert, having no radar facilities to monitor the aircraft, permitted a descent to 3,000 meters the NDB. At 10:09:57, the aircraft collided with a rocky mountain slope at an altitude of 2,520 meters while descending in clouds. All 47 occupants were killed.
Probable cause:
The accident was caused by a combination of the following factors:
- The captain's violations of the flight rules set forth in the policy documents manifested in unsatisfactory navigation, straightening the route and premature unauthorized descent to a height below the minimum safety altitude, which resulted in a collision with a mountain.
- Violations of ATC rules in their zones by ATC dispatchers of Erebuni, Kafan and Stepanakert airports, expressed in failure to comply with the rules of air traffic control and non-interference in the actions of the crew who violated the rules of navigation and flight regime, which did not allow timely prevention of the aircraft collision with an obstacle. The dispatchers at Yerevan-Stepanakert have a stereotype of work: to allow those conditions of approach, which the crews requested. These violations became possible due to shortcomings in the organization of flight work, flights and air traffic control at the Yerevan-Stepanakert MVL of the Armenian and Azerbaijani State Administration.
