1950 Aeroflot Ilyushin Il-12 crash
[1] The aircraft was conducting a passenger flight from Alma-Ata, piloted by a crew consisting of commander (KK) Vasily Alexandrovich Alexandrov, co-pilot Nikolay Alexandrovich Fedulov, navigator Boris Yuryevich Kobets, flight engineer Ivan Vasilyevich Tregubov, and radio operator Anatoliy Petrovich Gerasimov.A 67-meter-high elevator was in the flight path, leading the crew to adjust their course to the right and fly at an 80° angle to the extended runway centerline.However, when the dispatcher granted clearance for landing on heading 30°, this added confusion and significantly worsened the situation.Furthermore, the large size of Karaganda airfield with its level approach paths and clear weather conditions should have allowed the crew to make a safe landing on one functioning engine.Contributing factors included the lack of qualified assistance from the airport commander, who delegated flight management to an insufficiently qualified dispatcher, and poor maintenance oversight, as evidenced by the concealed engine failure before the test flight.
