A Ilyushin 18B aircraft experienced a catastrophic failure during a takeoff at Alma-Ata (now Almaty, Kazakhstan). Two passengers were killed. Aeroflot flight X-19, a domestic service flight, was en route from Alma-Ata to Moscow-Domodedovo with a stop at Semipalatinsk. Poor weather conditions, including a wet runway with melted snow and reduced visibility of 700 meters, resulted in a takeoff roll where the flight engineer shut down engine number 3 and feathered the propeller. The aircraft deviated to the right, leaving the paved surface, and subsequently collided with a 70 cm high mound on the shore of a small river, leading to a hard landing on a hillside.A Ilyushin 18B aircraft experienced a catastrophic failure during a takeoff at Alma-Ata (now Almaty, Kazakhstan).
