Circumstances:

The aircraft departed Nizhnevartovsk on a charter flight to Bugulma, carrying four crew members and 37 employees from an oil company. Weather conditions in Bugulma were poor with clouds down to 80 metres, icing conditions and a visibility of 800 metres. At an altitude of 1,100 metres on approach, the crew encountered icing conditions but did not consider it necessary to activate the deicing systems. Still descending to the altitude of 900 metres, the icing alarm sounded in the cockpit but the captain decided to continue the approach in such configuration. After the crew selected the flaps down to an angle of 30°, he was cleared to land when the aircraft became unstable and departed the approach path to the right. After the aircraft crossed the permissible deviation limit, the crew was instructed by ATC to initiate a go-around procedure. The captain increased engine power and initiated a go-around maneuver when the aircraft adopted a high angle of attack then stalled and pitched down to an angle of 75-80°. At a speed of 260 km/h, the aircraft struck the ground 802 metres short of runway and was destroyed upon impact. The wreckage was found 598 metres to the right of the extended runway centerline and all 41 occupants were killed.

Probable cause:

The accident was the consequence of the combination of the following factors:
- Icing conditions and poor weather conditions that were underestimated and misevaluated by the flight crew,
- An excessive accumulation of frost on the stabilizers (up to 15 millimetres),
- Failure of the crew to activate the deicing systems prior to enter the clouds,
- The decision of the captain to continue the approach after the icing alarm sounded,
- The crew selected flaps down to an angle of 30° without inspecting the wings and stabs surfaces, (in icing conditions, flaps should be deployed in 15° max),
- The flaps were not retracted when the crew initiated the go-around procedure, which caused the aircraft to adopt a high angle of attack,
- Poor crew interactions,
- Lack of crew supervision and mutual monitoring and checks.

Circumstances:

The aircraft departed Saint Petersburg-Pulkovo Airport on a cargo flight to Voronezh, carrying seven passengers, three crew members and a load of electronics and TV sets. While climbing to an altitude of 860 metres, the aircraft entered an uncontrolled descent and crashed in the Gulf of Finland, about 150 metres offshore. All 10 occupants were killed.

Probable cause:

The exact cause of the loss of control could not be determined. Nevertheless, it was reported that oxygen masks deployed during initial climb and that both engines were running at high power at impact.

Circumstances:

Following a wrong approach configuration, the crew passed over the runway threshold at a height of 30 meters and an excessive speed of 350 km/h. Rather than initiating a go-around procedure, the pilot-in-command continued and the aircraft landed 710 meters past the runway threshold. Unable to stop within the remaining distance, the aircraft overran at a speed of 225 km/h, lost its undercarriage then slid for about 317 meters and eventually collided with concrete blocks (2 meters high), bursting into flames. 29 passengers were injured while 34 other occupants were killed, among them all four crew members.

Probable cause:

Wrong approach configuration on part of the flying crew (too high on the glide and excessive speed) who failed to initiate a go-around while the landing procedure was obviously missed. The concrete blocks struck by the airplane were part of construction work for the new runway. The following contributing factors were reported:
- The crew violated/neglected various procedures,
- Lack of crew discipline,
- Poor crew coordination,
- The crew failed to use all available braking systems.

The crew continued the approach with an excessive rate of descent and at too high speed. Upon touchdown, the aircraft bounced three times then landed on its nose gear that collapsed. The aircraft slid for few dozen meters then overran and came to rest 83 meters past the runway end, bursting into flames. All 33 occupants were evacuated safely while the aircraft was destroyed.

Probable cause:

Wrong approach configuration on part of the crew who completed an approach and landing in a nose-down attitude with excessive speed and rate of descent. It was also determined that the braking systems were partially inoperative due to hydraulic failure, which was considered as a contributing factor.

During the takeoff roll at Luang Namtha Airport, after V1 speed, the crew started the rotation when the flight engineer decided to abort the takeoff procedure without any coordination with both pilots. Unable to stop within the remaining distance, the aircraft overran and collided with a building. All 35 occupants were rescued while one person on the ground was killed.

Probable cause:

It was determined that the crew failed to prepare the flight according to published procedures. Prior to departure, the crew incorrectly calculated the weight and balance and it was determined that the aircraft has been incorrectly loaded as the CofG was too far forward, out of the enveloppe. Poor crew coordination was a contributing factor.
