Narrative:
The Antonov struck a mountainside at an elevation of 2370 m, 21 m below the summit. The crew failed to change heading while descending towards Alma-Ata (now named Almaty). Air traffic control didn't monitor the flight for 2 minutes when the aircraft deviated from the airway. Upon noticing the deviation, the controller instructed a correcting right turn. The flight never responded, because communications in the vicinity of the mountain massif were unstable.
The aircraft operated on a flight from Biysk to Leninabad (now named Khujand, Tajikistan) with an en route stop at Almaty.
