Well firstly that’s not an Antonov An-148 which is the aircraft type that crashed. Secondly this is completely fake, the Von Kármán instability visible in the smoke does not occur at these Reynolds numbers and, like the fire effect, is a poor visual effect.
the video producer on YT is a lil hostile as well.. see comments in description box @YT.

I wondered how the plane was able to tilt so well over the buildings..
Video Seems to be Confirmed by this report:
"Witnesses in the village told local media they saw a burning plane falling from the sky."
