Investigation Summary
Shortly after departing Syktyvkar for the final leg to Moscow, the crew received a fire warning for the rear cargo hold. The fire was extremely aggressive, quickly filling the passenger cabin with thick, toxic smoke. The pilots declared an emergency and began a rapid descent, attempting to return to Syktyvkar. However, the deteriorating conditions inside the aircraft and the intensity of the blaze made reaching an airport impossible. The crew was forced to attempt an emergency landing in a densely forested area. The aircraft struck trees and broke apart, with the fire continuing to consume the wreckage. While 38 people survived the initial impact and fire, 54 others perished, many due to smoke inhalation or the severity of the crash in the rugged terrain.
Final Conclusions
The exact cause of the fire was never definitively proven, but investigators strongly suspected it originated from hazardous materials carried by a passenger in their luggage. The rapid development of the fire suggested the presence of flammable liquids or chemicals that bypassed security screening. The crew's decision to land immediately was necessitated by the loss of cabin visibility and the threat of structural failure, though the chosen site was unsuitable for a safe landing.
