Six minutes before the estimated time of arrival in Baturino, while cruising at an altitude of 200 meters, the engine failed. The crew elected to make an emergency landing when the airplane struck trees and crashed inverted in a wooded area located 13 km from Baturino. The captain was killed while both other occupants were injured.
Probable cause:
The exact cause of the engine failure could not be determined. However, it is believed it may be caused by an excessive accumulation of calamine on the intake valves.

Circumstances:
The crew was cleared to takeoff from runway 30 at Irkutsk-Intl Airport, bound for Kazachinskoye, carrying 11 passengers and a crew of two. While climbing to an altitude of 270 meters in limited visibility, the AN-2 collided with an Aeroflot AN-12B registered CCCP-12985 that was carrying seven crew members who were performing a local training flight. Following the collision, the AN-2 went out of control and crashed in flames 200 meters further. All 13 occupants were killed. The crew of the AN-12 elected to make an emergency landing when the aircraft crash landed in a prairie located 3,980 meters past the runway end. It slid on the ground for 220 meters before colliding with a concrete mast that cut the airplane in two. All seven crew members escaped uninjured.
Probable cause:
It was determined that the collision was the consequence of wrong decision and poor planning on part of ATC acting in the tower at Irkutsk-Magan Airport. Lack of visibility was considered as a contributing factor.

Circumstances:
The crew was engaged in a local training mission at Irkutsk-Intl Airport. During a ninth approach to runway 30, the crew was cleared to initiate a go-around according to the training program. While climbing to an altitude of 270 meters in limited visibility, the AN-12 collided with an Aeroflot PZL-Mielec AN-2R registered CCCP-49342. En route to Kazachinskoye, the AN-2 just took off from the same runway with 11 passengers and two pilots on board. Following the collision, the AN-2 went out of control and crashed in flames 200 meters further. All 13 occupants were killed. The crew of the AN-12 elected to make an emergency landing when the aircraft crash landed in a prairie located 3,980 meters past the runway end.

Circumstances:
The airplane departed Ulan-Ude at 0700LT on a cargo flight to Ufa with intermediate stops in Krasnoyarsk, Novosibirsk, Omsk, Petropavl, Kurgan and Chelyabinsk, carrying five crew members, three passengers and a load of 663 kg of various goods. About 20 minutes after takeoff, while cruising at an altitude of 2,400 meters, a passenger announced to the crew that a fire erupted in the rear part of the cabin. Smoke spread in the cabin and the cockpit and as the crew was unable to extinguish the fire, the captain decided to reduce his altitude and attempted an emergency landing in a prairie. The aircraft crash landed and came to rest in flames in an open field located 4 km from the village of Kharat. All eight occupants escaped while the aircraft was partially destroyed by fire. 40 hours later, a female passenger died from her injuries.
Probable cause:
The aircraft was carrying several wooden crates containing bottles of 20 liters of flammable products placed on a carpet of wood chips. It is believed that these boxes had been used many times in the past but had not been cleaned and the wood chips were soaked with flammable products, maybe because some of the bottles were not properly sealed. In flight, the hot air pulsed into the cabin via the heating system caused the wood chips to burn and the fire could not be extinguished by the crew.

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.

Circumstances:
The airplane was completing a flight from Sverdlovsk to Krasnoyarsk with an intermediate stop in Kamensk-Uralski, carrying six crew members and six passengers accompanying the cargo composed by 10 tons of various metallic materials. En route from Kamensk-Uralski to Krasnoyarsk, the crew was informed about poor weather conditions at destination and was instructed to divert to Yeniseysk Airport. On approach by night, the airplane descended below the glide and was too low when the copilot informed twice the captain they should initiate a go-around. For unknown reason, the captain continued the approach when the airplane, in a slight nose-down attitude, struck the ground with its nose gear 1,933 meters short of runway threshold. It bounced and flew for about 374 meters then struck trees and crashed 612 meters after initial impact. The aircraft was destroyed and the navigator was killed while 11 other occupants were injured.
Probable cause:
Poor approach planning on part of the crew who failed to follow the approach procedures and descended below the glide in poor visibility due to fog and night. The following contributing factors were reported:
- The fog reduced the visibility and considerably complicated the flight process,
- When approach lights were turn on in foggy conditions, this resulted in a screen that blinded the pilots,
- The captain's decision to continue the approach below the prescribed minimum altitude when he should have initiate a go-around procedure.

Circumstances:
Shortly after takeoff from Koma at 0706LT, bound for Novoselovo, the crew encountered poor weather conditions with limited visibility due to snow falls. About six minutes after departure, the airplane collided with a hilly terrain located near Novoselovo (the Novoselovo Airport is located 18 km west of Koma). The wreckage was found later in the afternoon. Three passengers were injured while 10 other occupants, among them both pilots were killed.
Probable cause:
It was determined that the crew was flying under VFR mode in adverse weather conditions (snow falls) when the airplane struck the ground. It was reported that the cold front should pass later that day so the crew was not informed about such conditions en route. A poor flight preparation was considered as a contributing factor.
