SMA PLT HAS LOSS OF ACFT CTL ON TKOF; ABORTS.

Narrative

I SET FORTH TO DEPART AMARILLO ARPT WITH THE GOAL OF FLYING TO OKLAHOMA CITY'S WILEY POST ARPT. THE EARLY AM HRS WERE SPENT DE-ICING THE ACFT AND PREFLT PREPARATION. EVERYTHING PASSED PREFLT INSPECTION. I THEN WAS CLRED TO TAXI FROM FBO TO HOLD SHORT OF RWY 4 FOR AN E DEP. I ACCOMPLISHED A SATISFACTORY RUN-UP. FLT CTLS WERE ACTING FREE AND CORRECT AS WELL. I WAS THEN CLRED TO TKOF. I PROCEEDED TO RECHK THE WINDS; WHICH WERE COMING FROM THE NW AT APPROX 10-15 MPH. I TURNED MY AILERONS INTO THE WIND AND SLOWLY PUT IN FULL PWR. AT THIS TIME; MY FEET WERE STANDING ON THE BRAKES. I OBSERVED ENG TEMP AND OIL PRESSURE TO BE GOOD; SO I RELEASED MY FEET FROM THE BRAKES. AS I BEGAN TKOF ROLL; I NOTICED AN ABRUPT TURN TO THE L INTO THE WIND. I IMMEDIATELY TRIED TO CORRECT DIRECTIONAL CTL BY INCREASING R RUDDER AND MAINTAINING MY WIND CORRECTION WITH THE AILERONS TURNED INTO THE WIND. THE ACFT CONTINUED TO TURN ABRUPTLY TO THE L AND APPEARED IT WOULD BE TURNING INTO A L CIRCLE IF ALLOWED TO CONTINUE. I IMMEDIATELY ABORTED THE TKOF BY FULL PWR REDUCTION AND TESTING THE BRAKES. THE PWR REDUCTION INITIALLY HELPED THE DIRECTIONAL CTL; BUT THE APPLICATION OF BRAKES SEEMED TOO ABRUPT AND POTENTIALLY HAZARDOUS TO BOTH THE ACFT AND PLT. THE NOSEWHEEL HAD ALREADY MET THE GRASS AT THIS POINT AND I OBSERVED NO OBSTACLES; SO I ALLOWED THE ACFT TO ROLL DOWN THE SLOPE. DURING THE ROLL I PERIODICALLY HIT 2 BUMPS; WHICH MOMENTARILY INCREASED THE GLIDE SPD. I APPLIED BRAKES TWICE DURING THE ROLL DOWN THE SLOPE AND IT ONLY CONFIRMED IT WAS IN MY BEST INTEREST TO GLIDE TO THE BOTTOM; WHERE I STOPPED. THERE WAS NO ACFT DAMAGE OR PLT INJURY.
