Aeroflot Flight 630 (Russian: Рейс 630 Аэрофлота) was a Soviet domestic passenger flight from Dushanbe to Moscow via Leninabad (now Khujand) that crashed on 24 February 1973, killing all 79 people on board, including five children.

[1] At the time of the accident, the aircraft sustained 20,404 flight hours and 9,590 pressurization cycles.

At an altitude of about 2,200 m (7,200 ft), the aircraft disintegrated due to high dynamic loads.

[citation needed] Having found no mechanical or structural failures in the aircraft, the investigation did not reach any conclusions, although it noted that the ATC did not track the flight at the last stage.

The Ministry of Aviation Industry of the USSR found that the accident was caused by a navigation error and the crew trying an intense left banking and descend, which led to the loss of control.
