Incident Narrative
At an altitude of 9,000 meters, the aircraft was in cruise when the copilot succeeded in sending a brief distress call. Shortly thereafter, control was lost and the aircraft entered a steep dive. The descent continued for approximately two minutes and thirty seconds before the aircraft disintegrated upon impacting a wooded area near Voznesenka, located about 28 kilometers east of Krasnoyarsk Airport. The wreckage was totally destroyed, and all 84 occupants were killed. Subsequent medical examination of the bodies revealed evidence of exposure to high temperatures and burns.
Probable Cause
The official investigation determined that several units of the Soviet Army Forces were engaged in a training exercise in the Magansk region, during which they launched multiple ground-to-air missiles. One of these missiles struck the left side of the aircraft, penetrating the fuselage and creating a hole measuring 20 cm in diameter. As a result of this damage, the aircraft became uncontrollable, entered a dive, and ultimately crashed.
