Aeroflot Flight 8641 was a Yakovlev Yak-42 airliner on a domestic scheduled passenger flight from Leningrad, Soviet Russia, to Kiev, Soviet Ukraine. On June 28, 1982, the flight crashed near Mozyr, Belarus, killing all 132 people on board. The crash was the first and deadliest one involving a Yakovlev Yak-42, as well as the deadliest aviation accident in Belarus.

The cause was discovered to be a failure of the jackscrew mechanism in the aircraft's tail due to metal fatigue, which resulted from flaws in the Yak-42's design. The aircraft lost control and went into a dive, disintegrating in mid-air. As a consequence of the accident, all Yak-42s were temporarily withdrawn from service until the design defect was fixed.

The crashed airliner was delivered to Aeroflot in 1981; at the time of the accident, it only been in service for about a year.
