Circumstances:

The aircraft departed Anadyr Airport on a cargo flight to Baku with intermediate stops in Chokurdakh and Tiksi, carrying five passengers and five crew members. While in cruising altitude by night, the aircraft suffered violent oscillations and started to pitch up and down. It entered an uncontrolled descent and at an altitude of 2,000 metres, it partially disintegrated and eventually crashed at a speed of 670 km/h in an icy river. All 10 occupants were killed.

Probable cause:

It was determined that the crew disengaged and re-engaged several times the automatic pilot system for unknown reasons. This created tail and elevators' movements and the reaction of the crew was inappropriate. The aircraft suffered violent oscillations on both roll and pitch axis then entered an uncontrolled descent. The partial disintegration was the consequence of aerodynamic forces that exceeded the aircraft certification.

Circumstances:

The aircraft was completing a cargo flight from Petropavlovsk-Kamchatsky to Kiev with intermediate stops in Lensk and Omsk, carrying seven passengers (among them technicians), six crew members and a load of fish. Rotation was completed at night at a speed of 225 km/h and the crew immediately raised the landing gear. The aircraft climbed with a rate of 6 metres per second and after passing the runway end at a height of 70 metres, the crew selected flaps up. The aircraft entered an uncontrolled descent, struck trees (22 metres high) at a speed of 380 km/h and crashed in a huge explosion 3,903 metres past the runway end and 400 metres to the left of its extended centerline. The aircraft was totally destroyed and all 13 occupants were killed.

Probable cause:

Wrong takeoff configuration on part of the crew who neglected several published procedures. The following contributing factors were reported:
- The total weight of the aircraft at the time of the accident was 7,5 tons above MTOW,
- Lack of crew training,
- Premature retraction of flaps during initial climb,
- Insufficient rate of climb/climbing speed.

Circumstances:

Following an uneventful flight from Moscow-Domodedovo Airport, the crew started the approach to Yakutsk-Intl Airport. Due to poor weather conditions and a visibility below minima, the crew diverted to Magan Airport. The aircraft overflew the runway threshold at a height of 22 meters and a speed of 297 km/h. It 'floated' for 22 seconds and eventually landed 1,647 meters past the runway threshold. For unknown reasons, the captain maintained the aircraft in a nose-up attitude and the nose gear landed nine seconds after the first touchdown only. Reverse thrust were not activated and the spoilers were finally deployed but too late. At a distance of 47 meters from the runway end, the captain shut down all four engine when the aircraft overran at a speed of 167 km/h. It went down an embankment, lost its undercarriage and came 538 meters past the runway end, 3,978 meters from the runway threshold and 2,331 meters from the touchdown point. Four passengers were injured and 185 other occupants were evacuated safely. The aircraft was damaged beyond repair.

Probable cause:

The accident was the consequence of a poor planned approach and a wrong approach configuration. The following contributing factors were reported:
- Lack of crew training,
- It was the first time (except for one crew member) that the crew was landing at Yakutsk-Magan Airport,
- Marginal weather conditions (visibility below minimums at the initial destination airport),
- Failure to comply with flight crew recommandations,
- Poor crew instructions and interaction,
- The crew failed to follow the published procedures for a standard approach and landing,
- Deviations in aircraft piloting during approach and landing, causing the aircraft to land too far down the runway,
- The pilot-in-command maintained the aircraft in a nose-up attitude for a period of 9 seconds between the main gear touchdown and the nose gear landing,
- The reverse thrust systems were not activated,
- The spoilers were deployed too late,
- Lack of leadership on part of the captain during the approach and landing,
- The crew did not make the decision to initiate a go-around procedure when the landing maneuver was obviously missed.

Circumstances:

The four engine aircraft departed Moscow-Domodedovo Airport at 1237LT with 99 passengers and 10 crew members on board. Following an uneventful flight of 5 hours and 42 minutes, the crew started the approach to Yakutsk-Intl Airport by night. After touchdown on runway 23 (3,300 meters long), the flight engineer mistakenly selected reverse thrust on engine n°2 and 3 only, letting both engines n°1 and 4 running at takeoff power. Both pilots took few seconds to identify the problem and the aircraft's speed was about 265-270 km/h and there were 655 meters of remaining runway. The captain attempted an emergency braking procedure when all tyres burst and the aircraft overran runway at a speed of 200 km/h, lost its undercarriage and came to rest 397 meters further, broken in three. All 109 occupants were evacuated, among them six were injured, two seriously. The aircraft was written off.

Probable cause:

The accident was the consequence of an error on part of the flight engineer who mistakenly selected reverse thrust on engine n°2 and 3 only, letting both engines n°1 and 4 running at takeoff power.
The following contributing factors were reported:
- The spoilers could not deploy because reverse thrust was not activated on all four engines,
- The crew was disorganized during the landing phase,
- Poor crew coordination,
- The mistake committed by the flight engineer was identified too late by the rest of the flying crew, ¨
- Heavy verbal charge during the landing phase,
- Insufficient professional skills of the flight engineer.
