Circumstances:
On the leg from Kazan to Sverdlovsk-Koltsovo Airport, while cruising at an altitude of 1,200 meters, both engines failed simultaneously. The pilot-in-command reduced his altitude and attempted an emergency landing when the airplane struck trees and crashed in flames in a wooded area located about 120 km west of Sverdlovsk. The wreckage was found the following morning at 0800LT. All five crew members and four passengers were killed while 17 other occupants were injured. The aircraft was destroyed.
Probable cause:
In-flight failure of both engines due to a fuel exhaustion. This was the result of a poor flight preparation on part of the crew who failed to fuel the aircraft with a sufficient quantity prior to departure. It was determined that a total of 1,108 kg of fuel was in the tanks, about 550 kg less than the necessary amount for this routing.

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:
The crew was completing a local training flight at Sverdlovsk-Koltsovo Airport. Following two landings and two approches, the crew started a new approach by night. During the last segment, at a speed of 260 km/h, the aircraft adopted a nose down attitude and struck the runway with its nose gear first that was sheared off upon impact. The airplane bounced and climbed to a height of about 10 meters before hitting the runway again in a nose down attitude. Upon impact, the airplane went out of control and veered off runway to the right before coming to rest in flames. The flight mechanic was killed while all four other occupants were injured. The aircraft was partially destroyed by fire.
Probable cause:
Wrong approach configuration on part of the instructor who adopted a too high speed on final (260 km/h) and failed to adopt a correct flare configuration, causing the airplane to adopt a nose down attitude and to struck the runway surface nose first, causing the nose gear to fail. It was determined that the rear trunk was loaded with a ballast weighing 600 kg instead of 1,000 kg which contributed to shift the center of gravity forward, causing the airplane to nose down. Analysis were not able to confirm if icing conditions may contribute to the accident or not.

Circumstances:
The aircraft was recently transferred from the Soviet Air Force to Aeroflot and the crew was en route from Sverdlovsk to Moscow-Bykovo with an intermediate stop in Kazan. Technical modifications should be brought on the aircraft, all documentation should be modified and adapted with a new color scheme on the fuselage. En route, the right engine failed and the captain decided to return to Sverdlovsk but he was unable to maintain a safe altitude. The crew jettisoned some of the cargo but few boxes struck the door and one of them remained partially blocked, causing drag. Losing altitude, the airplane struck trees and eventually crashed in a wooded area located near Didino, about 65 km west of Sverdlovsk-Koltsovo Airport. The airplane was destroyed, three crew members were injured and the fourth occupant was killed.
Probable cause:
Failure of the right engine in flight due to fuel starvation. It was determined that the fuel selector was connected to the left rear tank which was empty. Only 200 liters were added in the tank prior to takeoff and the crew forgot to change the fuel selector in flight to another suitable tank. It is also reported that the crew failed to take the appropriate measures to maintain a safe control of the airplane with one engine inoperative and the captain maintained an insufficient speed of 150 km/h instead of 170 km/h, which contributed to the loss of altitude.

Circumstances:
The aircraft departed Izhevsk Airport at 0220LT bound for Sverdlovsk and continued at an assigned altitude of 2,400 meters. On final approach to Koltsovo Airport, at a height of 250 meters, the right engine failed. The airplane lost height, struck trees and crashed. Both pilots were killed while all three other occupants were injured. The aircraft was destroyed.
Probable cause:
Failure of the right engine because it was connected to a empty fuel tank. Poor flight supervision on part of the flying crew and failure of the crew to switch the fuel selector on a suitable tank in due time.

Circumstances:
One minute after takeoff from Sverdlovsk-Koltsovo Airport, while in initial climb, the airplane banked left and right and encountered difficulties to gain height when it stalled and crashed 250 meters past the runway end. The wreckage was spotted 150 meters to the left of the runway centerline. Both pilots and three passengers were killed while ten other occupants were injured. Two weeks after the accident, a passenger died from his injuries.
Probable cause:
It was determined that the flaps were deployed at 25° for takeoff, too much for this procedure. Thus, the aircraft's speed after rotation was too low, deteriorating its stability and its lateral control. Investigations were able to determine that the flying crew failed to identify and eliminate the abnormal behavior of the aircraft during initial climb, probably because his attention was diverted. This situation led the aircraft to stall and the distance between the aircraft and the ground was insufficient to expect a recovery. At the time of the accident, the crew was on duty since 13 hours and 40 minutes and the day before, it observed a ON duty period of 17 hours. Thus, it is believed that fatigue accumulated during these two consecutive days, which could be considered as a contributing factor.

Circumstances:
Shortly after takeoff from Verkhnyaya Salda Airport, while climbing to a height of 30-40 meters, both engines failed almost simultaneously. The airplane stalled, hit power cables and eventually crashed in flames in a field located 1,500 meters past the runway end. Three crew members and a passenger were killed while three other occupants were injured. The aircraft was destroyed. The crew was completing a cargo flight from Verkhnyaya Salda to Omsk with an intermediate stop in Sverdlovsk on behalf of the Ministry of Aviation Industry (MAP - Ministerstvo Aviatsionnoi Promyshlennosti).
Probable cause:
It was determined that both engines failed due to a fuel exhaustion. Investigations confirmed that the fuel selector was connected to the left rear fuel tank that was empty. At the time of the accident, one of the passenger was seating at the copilot seat, against the published procedures. Also, it appears that most of the crew members were intoxicated, which was considered as contributory factors.

Circumstances:
The aircraft departed Kazan Airport at 2250LT in good weather conditions bound for Sverdlovsk-Koltsovo Airport. The crew was cleared to climb to 3,000 meters and later, encountered marginal weather conditions with clouds, icing conditions and light snow. In such conditions, the crew requested permission to reduce his altitude and descended to 1,800 meters in icing conditions. The radio operator tried several times to contact ATC in Koltsovo without success. Unable to locate his position due to low visibility and the failure of the radiocompas, the crew lost his orientation and due to a imminent fuel exhaustion, the captain decided to attempt an emergency belly landing. The airplane hit trees and crashed in a prairie located about 70 km west of Sverdlovsk and was damaged beyond repair. All 10 occupants were wounded and the copilot died from his injuries a day later.
Probable cause:
It was determined that the accident resulted from a loss of orientation on part of the crew leading to an emergency landing attempt due to exhausted fuel reserves. The following factors were considered as contributory:
- weather conditions deteriorated en route with icing conditions that were not reported in the weather forecast bulletin transmitted to the crew prior to departure,
- malfunction or failure of the radiocompas and a communication antenna, probably due to icing conditions,
- negligence on part of the crew who failed to follow the procedures for a radiocompas navigation, failed to perform the appropriate heading and tracking calculations and failed to refer to the direction-finding (ADF) values,
- failure of the air traffic controller who authorized the crew to climb to the altitude of 3,000 meters with the presence of severe icing conditions,
- crew fatigue due to a near 14 consecutive hours duty time,
- a copilot was refused on board before departure due to intoxication and the captain decided to do the flight without him. As a result, the flight was started with a limited crew which was also considered as a contributing factor.

On the approach to land at Sverdlovsk-Koltsovo Airport by night and foggy conditions, crew dropped below the glide path due to pilot error. Aircraft touched tree tops 900 metres behind the outer marker and 160 metres to the right of the runway's extended centerline and crashed in a meadow 220 metres further on (3,100 metres from the perimeter of the airfield). Two crew and two passengers were killed while all 23 other occupants were injured, one of them seriously.
Probable cause:
Wrong approach configuration, poor discipline and inappropriate decisions on part of the crew who decided to continue the approach in poor visibility. In such conditions, it would be recommended to initiate a go around procedure.
