During a test flight out of Br'ansk AFB, the Antonov made a turn with maximum rudder deflection. At an altitude of 6000 m the plane entered a slip. The captain manoeuvred the plane in an attempt not to lose height, but the Antonov attained a critical angle of attack. It entered a spin and broke up in the air.
