Khanty-Mansiysk | Bureau of Aircraft Accidents Archives

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:

En route from Khanty-Mansiysk to Tobolsk, while cruising at an altitude of 191 meters, the crew encountered poor weather conditions with heavy rain falls and very limited visibility. The single engine aircraft struck the chimney of an electrical plant, stalled and crashed, bursting into flames. Both pilots were killed.

Probable cause:

The crew failed to follow the published procedures and the assigned route. At the time of the accident, the aircraft deviated from the prescribed route and its altitude was insufficient. The lack of visibility due to poor weather conditions was a contributing factor.

Circumstances:

The aircraft suffered an incident at Chita Airport last April 18 when the nose gear collapsed on landing. Following repairs, the crew (three pilots and two engineers) was engaged in a local test flight out from Khanty-Mansiysk Airport. While cruising at an altitude of 6,000 meters, the ailerons were deployed to an angle of 8,5° then the aircraft turned to the right. Eight seconds later, it went out of control, overturned and entered a dive. With a rate of descent of 100 meters per second, the aircraft reached the speed of 620 km/h. With a positive acceleration of 5,25 g the left wing separated and struck the base of the tail that was torn off. The aircraft continued its uncontrolled descent until it crashed in an open field located near the Ob River, about 19 km northwest of the Khanty-Mansiysk Airport. The aircraft was destroyed and all five crew members were killed. The wreckage was found a day later.

Probable cause:

It was determined that the captain elected to perform a barrel in flight, in violation of all published procedures in force.

Circumstances:

Following an uneventful flight from Khanty-Mansiysk, the crew was cleared to continue the approach to runway 25 when he encountered marginal weather conditions with low clouds (130 meters above the ground) and limited visibility. While on approach at an altitude of 150 metres, the single engine airplane collided with a Mil Mi-8T. Registered CCCP-25686, it just took off from Surgut Airport bound to Nefteyugansk with 21 passengers and three crew members on board. Following the collision, both airplanes crashed in a wooded area, 600 meters from each other. Both machines were destroyed and none of the 38 occupants survived the collision.

Probable cause:

The collision was the consequence of wrong decisions on part of ATC at Surgut Airport who cleared the Antonov AN-2 crew to continue the descent while they actually had no idea of his real position. Following an accumulation of negligences, ATC failed to coordinate both movements, failed to inform both crews about the presence of a second aircraft in the traffic pattern and authorized the crew of the helicopter to take off while they did no have any idea about the exact position of the Antonov. The lack of visibility caused by the presence of low clouds remained a contributing factor, as well as the fact that the Antonov AN-2 crew continued the descent below weather minima.

Crash of a PZL-Mielec AN-2V in Khanty-Mansiysk

Circumstances:

While taking off from Khanty-Mansiysk Airport, the single engine airplane encountered difficulties to gain height. With an insufficient speed, it struck trees located past the runway end, stalled and crashed. All 35 occupants escaped, some of them were injured, and the aircraft was damaged beyond repair.

Probable cause:

The crew elected to takeoff with 33 passengers on board while the AN-2 is not certified to carry so much passengers. It was determined that the total weight of the aircraft was well above the MTOW at the time of the accident. In such conditions, it was not possible for the crew to takeoff.

Circumstances:

On final approach to Khanty-Mansiysk Airport, the crew failed to realize his altitude was insufficient when the airplane struck a snow covered field. It bounced then crashed in flames short of runway threshold. Four crew members were seriously injured while 43 other occupants were killed. The aircraft was destroyed.

Probable cause:

Possible wrong approach configuration and errors in the piloting techniques, expressed in an inaccurate determination of the airplane's altitude during the final stage of the approach.

Circumstances:

The airplane departed Tyumen-Plekhanovo Airport on a schedule service to Samarovo (now Khanty-Mansiysk), carrying one pilot and six passengers, four adults and two children. Approaching Samarovo, weather conditions deteriorated with snow falls reducing the visibility below one km. The pilot overflew Samarovo without any visual contact and continued until weather conditions improved. At this time, the pilot decided to return to Samarovo despite the fact that the weather was still bad. Approaching from the north, he attempted to land in a pasture when he lost control of the airplane that crashed 15 km north of Samarovo. All seven occupants were killed.

Probable cause:

The pilot deliberately decided to return to Samarovo for landing despite poor weather conditions.
The following contributing factors were identified:
- The weather bulletin transmitted to the pilot was expired and did reflect the actual weather conditions at destination,
- Absence of control points on the route Tobolsk - Samarovo,
- The pilot's lack of experience and training in instrument flights.
