The crash might have been caused by weather conditions, human error or technical failure, according to TASS citing an emergency source. The source added that there were no extreme weather conditions in the Moscow region at that time.

The Federal Air Transport Agency (Rosaviatsiya) said air traffic control had lost radio contact with the ill-fated plane “a few minutes” after take-off, and it disappeared from radar screens while flying over the Ramenskoe district of the Moscow region, TASS reported.

Interfax reported that the An-148 was manufactured less than eight years ago. It was first operated by Rossiya Airlines, including on international routes, and then was leased to Saratov Airlines.
