A Tupolev 104B passenger jet was destroyed when it crashed shortly after takeoff from Sverdlovsk (now named Ekaterinburg), Russia. All 100 passengers and eight crew members were killed.
Aeroflot flight 3932 took off at 20:33 on a 256° heading. The crew were instructed to make a procedure left turn after takeoff and climb to 1500 m. The airplane climbed through the clouds and the crew initiated the procedure turn. The bank angle was sharp at 35-40 degrees. At 20:37, at an altitude of 1200 m, the bank angle increased to 75-80 degrees. Control was lost and the plane descended at a rate of 75 m/sec. It crashed into a forest and burst into flames.
It appeared that the Tu-104 suffered a failure of the AC power to the artificial horizons.
Flight SU3932 covered the route Sverdlovsk-Omsk-Novosibirsk-Chita-Khabarovsk-Vladivostok.
