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:

The aircraft was engaged in a cargo flight from Farikha to Naryan-Mar, carrying a load of fish for a total weight of 1,155 kilos. After takeoff, while climbing to a height of 60 meters with a speed of 110 km/h, the crew turn off the lights. Five to six seconds later, control was lost. The airplane banked left to 20-25° then nosed down and crashed in an icy field located 1,124 meters past the runway end. The aircraft was destroyed by impact forces and a post crash fire and both pilots were killed.

Probable cause:

The exact cause of the accident could not be determined with certainty as the aircraft was totally destroyed and the engine and its components could not be analysed. Nevertheless, the assumption that the loss of control was the result of a spatial disorientation that suffered the pilot-in-command was not ruled out.

Circumstances:

The aircraft was flying too low and deviated from the prescribed flight path to the south by 15 km while encountering below-minima weather conditions (poor visibility). At a height of 300 meters, the single engine aircraft collided with tree tops on a hill located southwest of Damanka (some 22 km west of Krymsk), crashed, caught fire and burnt out. The copilot survived and the captain was killed.

Probable cause:

Poor flight preparation on part of the crew who decided to continue in below-minima weather conditions.

Circumstances:

On approach to Saratov-Tsentralny Airport by night, the crew encountered poor weather conditions with fog, clouds from 100 to 1,000 meters and icing conditions. While approaching at an altitude of 400 meters with flaps and landing gear up, the aircraft nosed down to a 7-9° angle then rolled to the right. It descended with a high vertical speed before crashing in flames 13 km short of runway threshold. The aircraft disintegrated on impact and the wreckage was found 1,300 meters to the right of the approach path. All 57 occupants have been killed.

Probable cause:

The aircraft was approaching at an estimated speed of 240-260 km/h with flaps retracted when it rolled to the right and started an uncontrolled descent with a high vertical speed. It is believed that the loss of control was probably caused by an excessive accumulation of ice on fuselage and wings which adversely modified the aerodynamic characteristics of the aircraft. Investigations determined that the aircraft had flown in icing conditions for a period of 3 minutes and 50 seconds, resulting in an accumulation of 15 millimeters of ice. The reason why the flaps were not deployed could not be determined.

Circumstances:

The crew encountered low clouds and poor weather conditions while following the valley of the river Tikhon-Yuryakh. The decision to return was taken too late so the aircraft was unable to clear the obstacles. It struck tree tops and crashed at a height of 1,080 meters into a mountain slope located near the Moma Pass (1,444 meters high) and 19 km northeast of Chumpu-Kytyl (Tyubelyakh). The aircraft was destroyed by impact forces and a post impact fire. A pilot and a passenger were injured while the second pilot and five passengers were killed.

Probable cause:

The accident was the consequence of:
- Wrong decisions taken by the crew,
- Poor flight preparation,
- Insufficient or erroneous information about enroute weather conditions.
