[1] The pilot suffered a broken leg requiring surgery, but all of the remaining passengers and crew escaped with only minor injuries.

An investigation ultimately concluded that the pilots of the aircraft had not activated the anti-icing system, which led to an accumulation of ice, resulting in engine failure.

Initially praised as a hero for his handling of the incident, the captain of the flight was ultimately criminally charged for violating safety protocols, leading to the crash.

Local authorities established a subsidized flight schedule between Kedrovy and Tomsk in 2019, with the cost of a ticket set at 2,000 rubles (about 80 US Dollars).

[2] On July 16, 2021, the flight from Kedrovy to Tomsk was delayed up to ten hours due to poor weather conditions.

[3]: 25–26 Prior to takeoff, the crew agreed that the first officer would be conducting active piloting and the captain would perform monitoring and communication duties.

Ten minutes into the flight, at an altitude of 3,000 metres (10,000 ft) and 70 kilometres (40 mi) from its origin airport, both engines of the aircraft failed.

[6] In interviews after the accident, the captain reported that after the aircraft entered thick cloud, icing occurred in the engines, causing both to fail.

[9] When the aircraft crashed, it disappeared from radar screens and the crew did not respond to air traffic control's radio requests.

[2] The crash site was located by helicopters that spotted a long path of fallen trees, the overturned aircraft, and smoke from a fire at the camp.

[3]: 33 In the days following the accident, a source close to the investigation told reporters that the main theory of the cause of the crash was that the aircraft entered a region of high humidity, which led to the air intakes of the engines becoming obstructed with ice.

[17] However, if the investigation finds that the accident was caused by something outside the control of the pilots, the crew can count on awards for skill and courage in safely guiding the stricken aircraft to the ground.

[10] On 28 July 2021, a source told reporters that the flight data showed that the aircraft had leveled off at 3,100 metres (10,200 ft), which was lower than the assigned altitude.

[20] The report stated that the amount of oil, fuel, and hydraulic fluid that had been loaded on the aircraft were appropriate for the scheduled trip, but that the flight crew had been severely overworked in the days preceding the accident, including having flown nine other flights totaling nearly 14 hours in the previous 24 hours, and had not been given time to rest.

[21] In July 2022, officials announced that they had concluded that the cause of the accident was determined to be that due to crew fatigue, the aircraft's anti-icing system had not been turned on at the appropriate time, which led to the accumulation of ice and engine failure.
