At liftoff, the right wing dropped and the airplane rolled to the right to an angle of 70°, causing the right wing to struck the snow covered ground 129 metres to the right of the runway. Out of control, the airplane crossed a taxiway, passed behind an air Koryo TU-154 that just landed (some debris struck the TU-154) and came to rest in flames, broken in three, 232 metres further. The wreckage was found 180 metres southeast of the runway end. 78 people, among them a stewardess, were injured, 12 people were unhurt. 24 occupants were killed, 15 passengers and nine crew members.

Probable cause:

The loss of control after rotation was caused by the combination of an asymmetrical fueling and pilot errors. It was determined that there was a difference of 1,500 kg of fuel between both wing tanks; 1,500 kg more in the right wing tank than the left wing tank, causing an excessive weight in the right wing. An excessive angle of attack after rotation above the allowable values and the lack of reaction from the pilot-in-command who failed to correct the situation for a period of eight seconds, caused the aircraft to reach an excessive right roll angle of 70° and to crash.

Circumstances:

The airplane was completing a cargo flight from a remote area located 75 km from Kirensk to Kirensk, carrying five oil barrels. Shortly after takeoff, while climbing, the cargo shifted, causing the CofG to be out of the envelope. The pilot attempted an emergency landing when, from a height of 15 meters, the airplane stalled and crashed. There were no injuries.

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. 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.

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.

After takeoff from Zhigalovo Airstrip, the pilot initiated a turn at low height when the airplane struck tree tops and crashed in flames in a wooded area by the Lena River. The occupant's fate remains unknown but the aircraft was destroyed.

Probable cause:

It was determined that the crew failed to follow the departure published procedures and initiated a turn below the minimum safe altitude of 600 meters. Also, the total weight of the aircraft was 250 kg above the MTOW.
