- Date: January 22, 1971
- Aircraft: Antonov AN-12
- Location: Surgut Khantia-Mansia okrug, Russia
- Fatalities: 14
- Phase of flight: Approach and landing
- Cause: Ice protection ineffective because engine bleed air valves were closed in flight, allowing ice to build up
An Aeroflot An-12 cargo flight from Omsk to Surgut crashed in flames about 15 km short of the runway at night in icing conditions. All 14 people on board were killed, and the investigation linked the loss to closed engine bleed air valves that left the ice protection ineffective.
