From the Wikipedia article

Aeroflot Flight 3932 was a flight operated by Aeroflot from Sverdlovsk-Koltsovo to Omsk Tsentralny Airport. On 30 September 1973, the Tupolev Tu-104 operating the route crashed shortly after takeoff from Sverdlovsk, killing all 108 passengers and crew on board.

Accident

Weather conditions at Sverdlovsk (now known as Yekaterinburg) were reported to be mild; visibility was over 6 kilometers, and light northwest winds.

Flight 3932 was on the Sverdlovsk-Vladivostok route with stopovers at Omsk, Novosibirsk (Tolmachevo), Chita (Kadala), and Khabarovsk airports. The flight crashed shortly after takeoff on the Sverdlovsk-Omsk part of the route.

The flight took off from Sverdlovsk - Koltsovo Airport at 18:33 MSK (Moscow time) and at 18:34:21 headed on a bearing of 256° for the route to Omsk. As a routine procedure, air traffic control instructed the crew to make a left turn and climb to an altitude of 1500 m after takeoff; the crew responded that they would report when they reached the altitude.

At 18:35:25 MSK, 5–6 seconds after setting the engines to standard power, with an altitude of 350 - 400 m and a speed of 480 km/h the crew began the left turn while in the clouds, with a bank angle between 35-40°. At 20:37 local time (18:37 Moscow time), when the flight was at an altitude of 1200 m, the bank angle reached 75-80°, after which the crew completely lost control of the aircraft. The plane crashed into a nearby forest at a speed of 270 km/h.

Investigation and cause

Cause

The aircraft crashed due to incorrect indications by the main artificial horizon and the compass system, caused by a failure of the electrical supply, resulting in spatial disorientation of the pilots. The aircraft crashed approximately five miles from Koltsovo Airport.
