An engine fire damaged the wing which came off as the aircraft attempted an emergency landing resulting in the deaths of 26 people.

[1] The crew from the 75th flight detachment were Trainee captain: Valentin Ivanovich Putikov, Non-staff pilot-instructor Vasily Ivanovich Grishanov, First Officer: Albert Modestovich Popov, Flag Navigator: (Syktyvkar United Aviation Group) Pyotr Ivanovich Suvorov, Flight engineer: Vladimir Alexandrovich Shishkin, Radio Operator: Yury Mikhailovich Nikonov, stewardess Lyudmila Serafimovna Volkov and Senior Navigator-Inspector of the flight service department: (Ministry of Civil Aviation) Nikolai Fedorovich Vanyukov.

Realizing that the fire was not extinguished and was rapidly spreading, the pilots decided to perform an emergency landing off-airfield and even selected a treeless site for this.

The airliner lost control and, entering a steep dive (at a 90° angle), crashed into a frozen swamp near the Bolshaya Vyatkina river, then disintegrated and burned.

According to the conclusions of the State Scientific Research Institute of Civil Aviation, there were no violations of the repair technology, maintenance rules, or operational deviations that could have caused the scuffing.
