Détails:
Aeroflot flight SU1802 departed Vinnitsa Airport (VIN) at 10:07 on a flight to Moscow-Bykovo (BKA). The An-24 climbed to the cruising altitude of 5700 m.
About 10:46 there was a sudden, sharp rudder deflection to the far right (25°) followed by a rapid course change and roll angles. The plane went to supercritical angles of attack, and then went into a tailspin. Descending at a vertical speed of 100 m/sec, the aircraft struck terrain.
The cause for the sharp rudder deflection was not found. It happened when the autopilot was disconnected. Possible reasons could be a failure in an electrical circuit or one of the pilots unintentionally pressing the rudder trim control switch when the flying on autopilot.
