UTair Flight 120 was a scheduled domestic passenger flight from Tyumen to Surgut, Russia. On 2 April 2012, the ATR-72 turboprop aircraft operating the flight crashed shortly after take-off from Roschino International Airport, killing 33 of the 43 people on board. Investigation carried out by the Russian Interstate Aviation Committee (MAK) revealed that the aircraft had not been de-iced prior to its take-off, even though it had been parked for hours in snowy condition. The crew of the flight were aware that ice and snow had accumulated on the aircraft, but decided not to de-ice it.

The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR, a joint venture formed by French aerospace company Aérospatiale and Italian aviation conglomerate Aeritalia. The number "72" in its name is derived from the aircraft's typical standard seating capacity of 72 passengers.
