Circumstances:
On final approach to Vladivostok Airport in limited visibility, the airplane struck the antenna of a radio station. Upon impact, an engine failed and the captain decided to attempt an emergency landing in a field located few km short of runway. There were no injuries among the occupants while the aircraft was damaged beyond repair. For unknown reason, the approach was continued below the glide.

Circumstances:
While descending to Odessa, the crew was informed by ATC that a storm was approaching the airport from the southwest. The crew continued the approach and after passing the outer marker, encountered heavy rain falls and turbulences. On short final, the airplane lost height and passed below the glide, struck approach lights and the roof of a building. On impact, an undercarriage was sheared off and remained on the building's roof. Out of control, the airplane plunged into the earth and crashed in flames in a field located short of runway 16 threshold. Two passengers and all nine crew members were injured while 83 other occupants were unhurt. The aircraft was destroyed by a post crash fire. Three hours after the crash, the navigator died from his injuries.
Probable cause:
It was determined that the loss of height on final was the consequence of an excessive reduction of thrust on part of the crew, who engaged the aircraft in an insufficient approach speed and a subsequent descent below the glide. The presence of turbulences (downdrafts) was considered as a contributing factor.

Circumstances:
After takeoff from runway 27 at Sverdlovsk-Koltsovo Airport, while climbing to a height of 130-150 meters, the right engine failed. This caused severe vibrations and the crew was unable to read the instruments properly. Trying to manipulate the throttle, the flight engineer inadvertently shut down the left engine. Due to a loss of power and insufficient thrust, the airplane lost height and the captain elected to make an emergency landing in a frozen pond located nine km west of the airfield. The aircraft landed at high speed, collided with several obstacles and eventually came to rest, broken in three, after a course of 1,220 meters. Two crew members, three passengers and two people on the ground were killed. 31 occupants were injured and 15 were unhurt. The aircraft was destroyed.
Probable cause:
Due to fatigue cracks, a blade located on the second stage of the compressor failed during initial climb, causing the failure of the right engine and severe vibrations. The inadvertent shut down of the left engine was a contributing factor.

Circumstances:
On final approach, the airplane was not properly aligned and the crew was instructed by ATC to make a go around. For unknown reason, the crew ignored this order and continued the approach. The airplane landed at an excessive speed and was unable to stop within the remaining distance, overran, lost its undercarriage and came to rest in flames. There were no injuries but the aircraft was destroyed.
Probable cause:
Wrong approach configuration on part of the flying crew who failed to make a go around.

Circumstances:
On the leg from Omsk to Irkutsk, at a distance of 160 km from the destination, the crew was informed about the deterioration of the weather conditions at Irkutsk Airport and was then diverted to Ust-Orda Airport. At this time, weather at Ust-Orda was as follow: cloud base at 250 meters, snow falls and a visibility of 3 km. On approach by night, the nose gear light was unserviceable so the captain decided to make a go around. For unknown reason, this procedure was delayed and he completed a low pass over the runway for about two km before making a turn to the left at a height of 10-15 meters when the airplane struck power cables. The aircraft stalled and crashed in flames on a hilly terrain near the airport. 46 passengers were uninjured while 19 occupants were injured. Three crew members were killed, the navigator, the radio operator and the mechanic. The aircraft was totally destroyed by a post crash fire.
Probable cause:
The decision of the captain to perform a go around was comprehensive but the very low pass (10-15 meters) above the runway was unacceptable. Investigations were able to determine that weather conditions at Irkutsk Airport were not as bad and the decision of the ATC to divert the crew to Ust-Orda was not necessary. Also, it was the first time that the pilot was flying to Ust-Orda and he did not have any knowledge about the environment at this airport, which was considered as a contributing factor.

Circumstances:
While cruising at an altitude of 11,000 meters on a flight from Omsk to Moscow, the crew was informed by ATC that the route to Vnukovo was closed due to weather deterioration and was instructed to divert to Sverdlovsk and to reduce his altitude to 10,000 meters. Two minutes later, the pilot sent a mayday message, reporting he was losing control of the airplane that entered a dive. By an angle of 80°, the airplane struck the ground and crashed in a field located along a railroad track near Kanash. The aircraft totally disintegrated on impact and all 80 occupants were killed, among them several foreign citizens such as three Sudanese, one Cambodian (Cambodian ambassador in China), eight Czech, three Romanian, one Polish, five East-German, five Hungarian, three Moroccan, two British, five French, one Iraqi and one Laotian.
Probable cause:
It was determined that the loss of control was caused by severe downdrafts, updrafts and atmospheric turbulences encountered at high altitude while changing its itinerary and altitude. The aircraft then reach a critical angle of attack before entering a dive.

Circumstances:
The aircraft departed Khabarovsk Airport with a delay of 3 hours and 35 minutes due to poor weather conditions. En route, while cruising at an assigned altitude of 11,000 meters, the crew encountered poor weather conditions and the captain decided to gain height to avoid the low pressure area. Shortly later, while at an altitude of 12,000 meters, the airplane went out of control and nosed down. It dove into the ground and crashed by an angle of 60° nose down in a field located near Chita. The airplane disintegrated on impact and all 64 occupants were killed. Debris were scattered on a distance of about 450 meters.
Probable cause:
The accident was the result of a loss of controllability due to atmospheric turbulences while cruising at an altitude of 12,000 meters which is in excess with the flying limitations and certification of the aircraft. Due to marginal weather conditions, the flight should be cancelled or postponed. The following factors contributed to the accident:
- Poor flight preparation on part of the ground operations, flying crew and flight director,
- The flight was delayed of 3 hours and 35 minutes, causing the aircraft to fly in worse weather conditions than predicted,
- Inadequate weather forecast,
- Poor weather conditions with atmospheric turbulences,
- Lack of clear instructions concerning the aircraft operation limitations (ceiling altitude),
- Violation of standard operating procedures.

Circumstances:
The crew was performing a training flight from Novosibirsk to Moscow-Vnukovo Airport with an intermediate stop at Sverdlovsk-Koltsovo Airport. While approaching Moscow, the crew informed ATC that the fuel reserves were insufficient and requested the permission to divert to the Dyagilevo Airbase located 180 km southeast of Moscow. Without checking local conditions, the flight director authorized the crew to divert to Dyagilevo. Upon arrival, the pilot was forced to make a go around due to poor weather conditions and it was then decided to divert to the Savasleyka Airbase located 200 km northeast of Dyagilevo. On final approach to Savasleyka Airfield, both engines stopped simultaneously. The airplane stalled, struck trees and crashed in a wooded area located 1,500 meters short of runway. The aircraft was destroyed and all eight crew members were seriously injured.
Probable cause:
Double engine failure caused by a fuel exhaustion.
