The 1951 Novosibirsk Il-12 crash was an aviation disaster involving an Ilyushin Il-12P aircraft operated by Aeroflot on 17 November 1951, which resulted in the deaths of 23 people.

The crew consisted of the commander (PIC) Pyotr Petrovich Averin, copilot Ruben Sergeyevich Aslanyants, flight engineer Ivan Matveyevich Kurchakov, and radio operator Viktor Ivanovich Kuznetsov.

Nonetheless, the head of AMS and a meteorologist verbally informed the Aerodrome control tower dispatcher Shipitsin and the deputy head of Novosibirsk airport for flight services Uvarov, who was the flight supervisor, that icing would still occur due to a delayed cold front.

However, immediately after liftoff, a left bank occurred, so the pilot decided to abort the takeoff, reduced throttle, and shut down the engines.

Khristovson then taxied to the parking area and went to the control tower, where he reported the incident, caused by snow on the aircraft, to Shipitsin, Zagorodny, and Averin (pilot of Il-12 CCCP-Л1775).

At 16:05, crew commander Khorunzhiy came to his Il-12, CCCP-Л1417, and found it covered in ice that could not be removed with a broom, so he refused to take off and demanded the aircraft be treated with hot water, reporting this to Zagorodny.

Assuming that the Li-2's runway excursion was caused by a wind shift, Broverman decided to change the takeoff direction by 180°—from 195° to 15°.

The impact caused the Il-12 to turn left by 135°, after which the fuselage was destroyed to ¾ of its length (up to the 34th frame out of 42) and caught fire.
