Circumstances:

The aircraft was completing a flight from Norilsk to Krasnoyarsk with intermediate stops in Podkamenaya Tunguska and Shushenskoye, carrying 23 passengers and 4 crew members on behalf of KrasAir (Krasnoyarskie Avialinii). While approaching Shushenskoye, the crew encountered poor weather conditions with a visibility limited to 400 metres due to snow falls. In such conditions, the crew lost his orientation and was unable to locate the destination airport. The captain decided to attempt an emergency landing when the aircraft crash landed in the taiga about 18 km from the airport. All 27 occupants were rescued, among them one passenger was slightly injured. The aircraft was written off.

Probable cause:

The crew lost his orientation in bad weather conditions following navigation error and false calculation regarding the wind component. The lack of ATC assistance was considered as a contributing factor.

Circumstances:

Following an uneventful flight from Tyumen, the aircraft was approaching Khanty-Mansiysk Airport by night and poor weather conditions due to snow falls and a visibility limited to 5,300 metres with a cloud base at 400 metres. On final approach, the aircraft descended below the MDA when it landed at a speed of 190 km/h on an helipad located 159 metres to the left of the runway and 950 metres from its threshold. The aircraft collided with three parked helicopters and crashed. Both pilots, a third crew member and two passengers were killed. The aircraft as well as three helicopter registered RA-22313, RA-25144 and RA-25939 were destroyed.

Probable cause:

The following findings were reported:
- The crew did not have sufficient information about the deterioration of the weather conditions at destination,
- The crew decided to continue the approach in a visibility that was below minimums,
- The power of the ground light system located at the helipad was higher than the runway light system, in conditions of limited visibility, which caused a wrong perception of the crew.

Circumstances:

Following an uneventful flight from Freetown, the three engine aircraft encountered windshear on final approach to Monrovia, lost height and struck the ground 5 metres before the runway threshold (0.8-1 meter below the runway elevation). The left main gear was torn off and the aircraft slid/rolled for about 300 metres before coming to rest. All 11 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

Loss of control on short final after the aircraft encountered windshear.

Circumstances:

Twenty-three minutes after takeoff from Tynda Airport, while cruising at an altitude of 5,700 metres, the crew encountered technical problems with the engine n°2 (central engine). Due to an excessive temperature of the turbine, the captain decided to shut this engine down (the engine n°2 is equipped with a thrust reverser system). While descending to Aldan Airport, the aircraft approached in a nose down attitude and struck the ground 90 metres short of runway threshold with a positive acceleration of 4 g. On impact, the nose gear collapsed, the aircraft bounced several times then slid for 800 metres before coming to rest on the runway. All 11 occupants evacuated safely while the aircraft was damaged beyond repair.

Probable cause:

The following findings were reported:
- The crew took the wrong decision to fly to Aldan Airport instead of the alternate,
- The approach was continued with excessive gap related to the approach speed and altitude,
- On final, the aircraft was in an excessive nose down attitude,
- The crew failed to identify and correct the wrong approach configuration.

After landing at Rostov-on-Don Airport, the three engine aircraft encountered difficulties to stop within the remaining distance. It overran, lost its undercarriage, struck a concrete wall and came to rest 870 past the runway end. All 10 occupants escaped uninjured while the aircraft was damaged beyond repair.

Probable cause:

Following a wrong manipulation, the flight engineer activated the thrust reversers on engine n°1 and n°3 but not on the engine n°2 that was providing full power. Such configuration reduced the braking action and the crew was unable to stop the aircraft within the landing distance available.

On final approach to Saposoa Airport, the crew realized that someone was walking on the runway. Instead of initiating a go-around procedure, the crew decided to landed long. After touchdown, the aircraft was unable to stop within the remaining distance, overran and came to rest in the Saposoa River. A pilot and seven passengers were killed while 23 other occupants were injured.

Probable cause:

Wrong approach configuration on part of the crew who landed too far down the runway, reducing the landing distance available.

In the morning of October 27, while the hijacker fall asleep, both pilots left the airplane and the police stormed the aircraft. The hijacker was able to detonate a home made explosive device in the cockpit and was killed. The aircraft was damaged beyond repair.

Probable cause:

Explosion of a home made explosive device.

Circumstances:

Following an uneventful flight from Krasnoyarsk, the crew was approaching Tura Airport when he encountered poor weather conditions and limited visibility upon arrival. Unable to establish a visual contact with the runway, the crew decided to initiate a go-around and followed a holding pattern. Two other approaches were abandoned during the following minutes. Eventually, the crew decided to divert to Vanavara Airport which is located 450 km southeast of Tura. Following a total flight time of 3 hours and 45 minutes, while descending to Vanavara Airport, all three engines stopped simultaneously. The captain attempted an emergency landing in a cleared area when the aircraft struck trees at a speed of 235 km/h. Out of control, it crashed on the shore of the Chamba river, coming to rest upside down. The wreckage was found 41 km north-northwest of Vanavara and all 28 occupants were killed.

Probable cause:

It was determined that all three engine failed simultaneously due to a fuel exhaustion. Following a poor flight planning, the crew decided to chose Vanavara as the alternate airport (450 km from Tura) while the airport of Baykit was located 110 km from Tura and weather conditions were good at this time.
The following contributing factors were reported:
- The crew incorrectly calculated the total amount of fuel necessary for the request flight and the alternate airport,
- The crew was unaware of the deterioration of the weather conditions in Tura after the ground personnel based at Tura Airport failed to conduct efficient observations and inform the crew accordingly,
- The deviation, allowed by crew during the first straight-in approach, which was caused, probably, by short-term de-energizing of the Outer Marker beacon and by incorrect determination by the crew of removal to VPP under these conditions,
- Failure of the crew to monitor the approach pattern parameters during the second and third approaches to Tura Airport in below minimums visibility,
- The crew started the descent to Vanavara Airport prematurely following a wrong flight altitude selection.
