Tupolev Tu-154B-2, Aeroflot Flight 7425

Tupolev Tu-154B-2, Aeroflot Flight 7425, on a domestic Karshi–Ufa–Leningrad route on July 10, 1985, crashed near Uchkuduk, Uzbek SSR, Soviet Union, on the second leg of its route. All 191 passengers and 9 crew were killed. An investigation concluded that the plane went down due to pilot error. The aircrew used an inappropriately low airspeed, causing vibrations that they incorrectly interpreted as engine surges. As a result, they further reduced engine power, causing the aircraft to stall and crash
