Aeroflot Flight 10 (1954)

Aeroflot Flight 10 was a scheduled passenger flight from Yuzhno-Sakhalinsk Airport to Vnukovo Airport with stopovers at Krasnoyarsk Airport and Severny Airport. On 27 September 1954, the Ilyushin Il-12 flying this route crashed near Severny Airport after it struck trees. Of the 29 occupants onboard, none survived.

Accident

The Il-12 departed Krasnoyarsk at 22:17. The visibility was forecast as 4–10 km at the time of takeoff. Despite a warning being received by the station at 00:12 that the airport was covered in fog and had poor visibility, the forecaster on duty reported the weather conditions to the crew at 00:25. As the aircraft approached Novosibirsk, the visibility worsened to about 400 m. The captain abandoned the approach due to the plane being too far to the left of the runway.

After a few minutes, the crew started another approach with a visibility of 100 m. Without sighting the ground, the pilot-in-command continued the approach, with permission from the air traffic controller, and descended below the decision height. At 00:57, the Il-12 struck trees and crashed into a wooded area near the airport, killing all 29 occupants onboard. There was no fire.

Flight 10 was approaching from the south, where there were no approach lights, and the non-directional beacon worked improperly.
