Circumstances:
The aircraft was performing a cargo flight from Yakutsk to Olyokminsk, carrying a load of various goods such as 70 kg of mail, 494 kg of garlic, spare parts, a welding machine, a screen and radio equipment for a total weight of 1,476 kg. While descending to Olyokminsk, the crew encountered poor weather conditions and followed visually the wrong river Sinyaya instead of Lena. Doing so, the aircraft descended prematurely and its altitude was insufficient while passing the outer marker. The aircraft struck trees and crashed on the slope of a wooded hill (434 m high) located 25 km short of runway threshold. The wreckage was found a day later and all four crew members were killed.
Probable cause:
Unable to determiner his exact position based on the ETA, the crew erroneously followed the Lena River. As a result of a premature descent, the aircraft collided with trees. ATC, unable to assist the flight by radar in marginal weather conditions, unreasonably gave permission to the crew to perform a straight-in approach, based only on the report of the crew.

Circumstances:
The crew was completing a flight from Magadan to Bilibino with intermediate stops at Berelekh, Zyryanka and Chersky. Due to poor weather at Bilibino, the aircraft, the crew and the passengers were grounded at Chersky for four days. Eventually, weather seemed to improve so the crew decided to depart Chersky in the morning of September 18. Few minutes after takeoff, the airplane entered a cloud area and while cruising at the altitude of 800 meters, it struck the snowy slope of Mt Belaya Strelka (975 meters high) located 46 km southeast of Chersky. The aircraft was destroyed by impact forced and a post crash fire and all 32 occupants were killed.
Probable cause:
The crew decided to modify his route without prior permission and continued the flight at an insufficient altitude in low visibility without any visual contact with the ground.

Circumstances:
The aircraft was completing a cargo flight from Yakutsk to Sangar, carrying a load of 3,100 kilos of apples. Descending to Sangar Airport by night, while at an altitude of 600 meters, the pilot informed ground he located the airport. Twice, the airplane overflew the airfield without landing and the crew was apparently unable to determine his position with certainty. While flying at low height, the right wing struck trees and was sheared off. Out of control, the airplane crashed on the southwest slope of Mt Vataala Hayata located near the village of Smorodinny, about 8 km southeast of the airport. The aircraft was destroyed by impact forces and a post crash fire and all five crew members were killed.
Probable cause:
A general power failure occurred in Sangar few minutes before the arrival of the aircraft. Due to the night and the presence of fog, the visibility was less than 3 km and the pilots interpreted the lights of Smorodinny village as those of Sangar and thus started the approach prematurely, causing the aircraft to struck trees and to crash. For reasons unknown, the crew had not been informed by ATC that Sangar was plunged into darkness and bad weather at destination.

Circumstances:
The aircraft was performing a cargo flight from Yakutsk to Zyrianka with an intermediate stop at Oymyakon, carrying two passengers, a crew of four and a load of 2,253 kilos of potatoes. While cruising at an altitude of 1,600 meters in clouds, the airplane went out of control, entered a dive and crashed in a wooded area located 95 km west of Oymyakon. The wreckage was found two days later in an isolated area. The aircraft was destroyed and all six occupants have been killed.
Probable cause:
It was determined that the crew failed to follow the procedures in flight and failed to pay attention to the fuel selector that was switched to an empty tank, causing both engines to stop. There was fuel remaining in other tanks but the crew failed to switch the fuel selector in due time. Due to fuel exhaustion, both engines failed and the airplane went out of control while flying in autopilot in clouds.

Circumstances:
The aircraft was performing a cargo flight from Magadan to Pevek with intermediate stops at Seymshan, Zyrianka, Nizhni Kresty, and Bilibino, carrying one passenger, a crew of five and two tons of apples. The takeoff was started by night and in snow falls from a contaminated runway. After a long takeoff course, the pilot-in-command completed the rotation at low speed. After liftoff, the airplane reached a high angle of attack, stalled and struck the runway surface several times. It continued for few hundred yards then banked left and eventually crashed in flames in a snowy field located 440 meters past the runway end. The passenger was slightly injured while all five crew members were killed. The aircraft was destroyed.
Probable cause:
The crew took the decision to takeoff from a contaminated runway that has not been properly cleaned prior to the accident. In such conditions, all safety conditions were not met and the aircraft performances were reduced. For undetermined reason, the crew decided to continue the takeoff run despite the course was too long and failed to take the right decision to abandon the departure procedure.

Circumstances:
The crew was performing a geophysical survey flight in the west part of Aldan, Yakutia. At the end of the mission, the crew was returning to the east and while flying face to the sun at a height of 1,046 meters, the single engine aircraft struck tree tops and crashed in flames in a dense wooded area located about 145 km west of Aldan. The captain and the flight engineer were killed instantly. The flight operator and the navigator were injured and walked away to find help. After four km walk, the navigator died from his injuries and his body was found thirteen days later on July 18. The flight operator eventually find help and was evacuated to a local hospital. At the time of the accident, the visibility was reduced to one km due to clouds.
Probable cause:
It was determined that the crew failed to take into consideration the high OAT ( 23°) and its effect on the rate of climb and the airplane's performances. Also, the following factors were considered as contributing:
- The crew failed to make any reconnaissance flight prior to the mission,
- Flying against the sun,
- Poor flight preparation.

One hour and twenty minutes after his departure from Nyurba, the crew arrived at Botyobiya and the captain started a steep descent (5 to 7 meters per second) and retarded the throttle when the aircraft struck the ground few meters short of runway threshold, bounced and crashed in flames 84 meters farther. The flight mechanic was killed while both pilots were seriously injured (burns). The aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
Poor piloting techniques on part of the pilot-in-command. Lack of supervision by the local authorities was considered as a contributing factor.

En route, weather conditions worsened and the pilot climbed from 1,400 to 2,000 meters. As the visibility deteriorated, the aircraft deviated from the prescribed flight plan by 12 km and later, the pilot-in-command reduced his altitude to 1,300 meters when the airplane hit the slope of Mt Hadaraniya (1,468 meters high) located about 175 km northeast of Batagay. Two passengers were injured while four other occupants were killed. The aircraft was destroyed by impact forces and a post crash fire.
Probable cause:
The accident was the consequence of wrong decisions on part of the crew who decided to modify his route without prior permission while he was flying in below minima weather conditions above a mountainous area. The following findings were reported:
- poor flight organization,
- poor analysis of the flight documentation,
- meteorological forecast that did not reflect the reality.

Circumstances:
Shortly after takeoff from Zyrianka Airport, while climbing to a height of about 20 meters, the left engine encountered problems and the crew tried to feather the propeller, without success. In such conditions, the pilot-in-command decided to attempt an emergency landing. At a speed of 140 km/h, the airplane hit trees and crashed in a wooded area located 600 meters past the runway end. The airplane was damaged beyond repair while all 16 occupants were rescued.
Probable cause:
When the undercarriage were raised after liftoff, the left engine suffered technical issues and the crew was forced to feather the propeller, without success. The propeller was then windmilling, causing drag. In such conditions, the aircraft lost height and the pilot elected to make an emergency landing. It was reported that the board mechanic was unable to response immediately to the engine issue because he was focused on instruments check and especially the speed indicator, which was considered as a contributory factor.
