Circumstances:
The airplane was completing a flight from Simferopol to Kerch, carrying six members of the Ministry of the Interior. On approach, the crew encountered poor weather conditions with fog, clouds down to 100 meters above the ground and a visibility limited to 500 meters. On final, at a speed of 220 km/h, the pilot-in-command decided to reduced his altitude to establish a visual contact with the ground when the airplane struck a concrete block of a power line. Flying at a height of 17 meters below the runway altitude, the airplane struck a house and crashed in flames some 2,610 meters short of runway. All four crew members and two passengers were killed while five other occupants were killed.
Probable cause:
The crew continued the approach below the glide without visual contact with the runway and ground. The accident was caused by the combination of the following factors:
- Overestimation of the vertical speed,
- Poor altimeter monitoring,
- Possible wrong altimeter setting,
- Absence of a radar at the airport allowing ATC to monitor the aircraft's approach path,
- Low visibility due to fog,
- Lack of information regarding weather conditions at destination.

Circumstances:
On approach to Vinnitsa Airport, the crew encountered poor weather conditions with fog, low clouds and freezing rain. Due to poor visibility, the captain decided to abandon the approach and made a go-around. Few minutes later, during a second attempt to land in similar conditions, the captain decided to make a second go-around and requested full power. At this time, the airplane banked left to an angle of 20-40° then stalled and crashed in flames 850 meters short of runway. The aircraft was totally destroyed and all 48 occupants were killed.
Probable cause:
The loss of control on short final was caused by an aerodynamic stalled for a reason which could not be determined with certainty. However, it was reported that a delay of 3 to 5 second elapsed from the decision to make a go-around and the selection of the speed levers in a forward position which could contribute to the stall.

Circumstances:
The crew departed Ulan-Ude-Mukhino Airport on a local training flight. Following several circuits, it was decided to shut down an engine to simulate a failure. After the propeller was feathered, the flight engineer mistakenly shut down the second engine. The crew completed a belly landing on the Bodorodski Island located about 8 km short of runway 26. The aircraft was partially consumed by a post crash fire and all crew members were slightly injured.
Probable cause:
Engine mistakenly shot down by the flight engineer during a single engine exercise.

Circumstances:
Following seven approaches and landings completed successfully, the crew started a eighth approach in good weather conditions. On final, the instructor thought that the admission pressure on the right engine dropped so he decided to shut down the engine and to feather its propeller without communicating with the rest of the crew. To compensate the loss of power, he asked the flight engineer to increase power on the left engine but the flight engineer inadvertently shot down the left engine when the right engine was just shot down as well. In such conditions, the pilot-in-command attempted an emergency landing when the airplane crash landed in a field located near Bykovo Airport. The aircraft was damaged beyond repair and three crew members were injured.
Probable cause:
The accident was the consequence of the combination of the following factors:
- Poor flight preparation,
- Lack of crew coordination,
- Lack of interaction between the instructor and the rest of the crew,
- Irresponsible actions on part of the flight engineer.

Circumstances:
The crew (one instructeur, a captain and a copilot under supervision) was engaged in a local training flight at Cairo-Intl Airport. Following five successful touch-and-goes, the crew initiated a sixth manoeuvre during which the pilot under training was supposed to perform a complete stop on the runway then to increase power and initiate a take off with one engine inoperative. After liftoff, while climbing to a height of some 50 meters, the airplane banked right to an angle of 90° then crashed by the runway shoulder. The airplane was destroyed and all three crew members were killed.
Probable cause:
It was determined that the pilot-in-command failed to observe the takeoff procedures and adopted a wrong takeoff configuration. The lack of supervision on part of the instructor and the captain was considered as a contributing factor.

Circumstances:
The aircraft departed Novosibirsk-Tolmachevo Airport at 0342LT and its crew was cleared to climb to 4,200 meters, altitude reached at 0353LT. At this time, the crew was cleared to continue to climb to the assigned altitude of 6,000 meters. Shortly later, while flying at an altitude of 5,400 meters, the airplane collided with a radiosonde weather balloon operated by the Hydrometeorological Service. The balloon struck the windshield and the nose cone and partially destroyed the cockpit. The airplane went out of control, entered a dive and partially disintegrated at the altitude of 2,000 meters before crashing in an open field located 20 km southeast of Toguchin. The airplane struck the ground at a speed of 300 km/h and was totally destroyed. All 45 occupants were killed. Some debris from the nose and the weather balloon were found more than 6 km from the main point of impact. The windshield was not recovered.
Probable cause:
In-flight collision with a radiosonde weather balloon while cruising by night. Apparently, the crew has not been informed about the presence of the weather balloon.

Circumstances:
Shortly after takeoff from Alexandria Airport, the crew informed ATC about the explosion of the left engine and requested the permission to divert to Cairo-Intl Airport for an emergency landing. Due to severe damages caused by the explosion, the crew was unable to lower the gear nor the flaps. Eventually, the captain decided to belly landed in a sandy area located near the runway 05. The airplane slid for dozen yards, came to rest and was damaged beyond repair while all 15 occupants escaped uninjured.
Probable cause:
Explosion of the left engine due to the presence of a foreign object in the rear cone of the left engine nacelle.

Circumstances:
The crew departed Bucharest-Otopeni Airport at 1300LT bound for Oradea. While descending in poor weather conditions, the airplane struck tree tops, stalled and crashed in a snow covered hill located in the Vlădeasa Mountain Range, about 73 km southeast of Oradea Airport. The wreckage was found three days later and a passenger was found alive while 20 other occupants were killed. The survivor told rescuers that at least eight other people survived the crash but later died due to extreme low temperature.
Probable cause:
Premature descent on part of the flying crew, causing the aircraft to pass below the minimum prescribed altitude. This resulted in a controlled flight into terrain. The lack of visibility due to marginal weather was considered as a contributing factor.

Circumstances:
Following an uneventful flight, the crew was cleared to descent to 2,700 meters and received all information related to the destination airport. Shortly later, the crew informed ATC about their ETA in eight minutes. As the pilot has the runway in sight, he was cleared to descend to 600 meters. While cruising at an altitude of 1,020 meters at a speed of 350 km/h in a 7° nose-down attitude and a 3° left bank, the airplane struck the slope of a mountain (1,081 meters high) located 40 km from the airport. The airplane disintegrated on impact and all 34 occupants were killed.
Probable cause:
It was determined that the ground collision was the consequence of a premature descent on part of the pilot-in-command who continued the approach below the minimum safe altitude. The lack of visibility caused by night and the lack of assistance on part of ATC were considered as contributing factors.
