This aircraft is destined for the Russian market, and probably for its allies. It doesn't matter that Russia can't import US/European parts, it still makes its own, including FBW and glass cockpit systems.
The trade embargo is reinvigorating the Russian economy, including its aerospace industries. The sanctions give Russian entrepreneurs the opportunity to invest in strategic industries as a substitute, as they are already doing in the agriculture sector. Can't import tomatoes from Spain? Get them from the Caucasus.
If EASA fails to grant the aircraft type approval, it's going to be tit for tat. Russian aircraft barred from overflying Europe? Think of the mess if Russia bars overflights over its terrirory. But it won't come to that. Already, countries like France and Italy are increasingly discontent with the sanctions imposed by European commission, as its hurting their economies, and causing anger amongst its farmers and industrialists.
Smart move, Europe. It's called 'shooting yourself in the foot', and 'cutting off your nose to spite your face'.
