THE PLT RPRTD THAT WHEN THE NOSE WHEEL TOUCHED DOWN DURING THE LANDING, A SEVERE VIBRATION BEGAN & THE ACFT VEERED TO THE LEFT. SHE SAID SHE PULLED THE YOKE AFT, BUT THIS HAD NO RESPONSE. ALSO, SHE SAID SHE APPLIED BRAKES, BUT COULD NOT STOP THE ACFT OR MAKE IT TURN RIGHT. SUBSEQUENTLY, THE ACFT DRIFTED INTO A SNOW BANK BESIDE THE RWY & NOSED OVER. A WITNESS SAID THE LEFT MAIN GEAR 'CAUGHT THE SNOW ON THE SIDE OF THE RUNWAY FOR APPROX 30 FEET, THEN AIRCRAFT TURNED INTO THE SNOW . . .'  AN EXAM OF THE NOSE LANDING GEAR WAS MADE, BUT NO MECHANICAL PROBLEMS WERE FOUND.
