Although the name Sukhoi is russian, there is not much russian in the aircraft considering all subsystems including:
Thales (avionics)
Liebherr (with Teploobmennik OJSC and PMZ Voskhod JSC) (Flight Control Systems)
Messier-Dowty (landing gear)
Intertechnique (Zodiac) (fuel system)
BE Aerospace (interior)
Curtiss-Wright Controls (fire protection system)
Honeywell (APU)
IPECO (crew seats)
Parker Hannifin (hydraulic system)
Hamilton Sundstrand (electrical system)
Meggitt Vibro-Meter (engine vibration sensor)
Saint-Gobain Sully (windows)
AeroCell (Nacelles and Thrust Reverser)
SAMCO (Passenger and Cargo doors)
Goodrich Corporation, Aircelle (engine nacelle)
All components are operating worldwide in thousands of flights daily without problems, so it seems it's not a hull related crash.
