Safety concerns have plagued Russia's airline industry, which has witnessed multiple fatal crashes in recent years, and the engine of a plane carrying Saudi Arabia's team caught fire earlier this week.
Russia's state aviation agency, Rosaviatsiya, said on Saturday that a Utair plane which was carrying Peru fans back to Moscow via Tyumen after watching their national side lose 1-0 to France in Ekaterinburg, had suffered engine failure.
"During the landing approach there was a failure in the second turboprop engine," a statement from Rosaviatsiya read. "As a result of the abnormal engine activity, smoke from overheated oil got into the passenger cabin of the aircraft through the air-conditioning system."
Rosaviatsiya said the smoke soon cleared from the cabin and that the pilot was able to safely land the plane on one engine.
A spokeswoman for Utair said media reports about a fire breaking out on the plane were incorrect.
"The crew acted as instructed and landed the aircraft as usual. The plane taxied in independently, the passengers left via the stairs without using the emergency equipment," she said in written comments to Reuters.
Utair is now working with aviation authorities to investigate whether a foreign object got into the engine, she added.
