Narrative:

I set forth to depart amarillo airport with the goal of flying to oklahoma city's wiley post airport. The early am hours were spent de-icing the aircraft and preflight preparation. Everything passed preflight inspection. I then was cleared to taxi from FBO to hold short of runway 4 for an east departure. I accomplished a satisfactory run-up. Flight controls were acting free and correct as well. I was then cleared to takeoff. I proceeded to rechk the winds, which were coming from the northwest at approximately 10-15 mph. I turned my ailerons into the wind and slowly put in full power. At this time, my feet were standing on the brakes. I observed engine temperature and oil pressure to be good, so I released my feet from the brakes. As I began takeoff roll, I noticed an abrupt turn to the left into the wind. I immediately tried to correct directional control by increasing right rudder and maintaining my wind correction with the ailerons turned into the wind. The aircraft continued to turn abruptly to the left and appeared it would be turning into a left circle if allowed to continue. I immediately aborted the takeoff by full power reduction and testing the brakes. The power reduction initially helped the directional control, but the application of brakes seemed too abrupt and potentially hazardous to both the aircraft and pilot. The nosewheel had already met the grass at this point and I observed no obstacles, so I allowed the aircraft to roll down the slope. During the roll I periodically hit 2 bumps, which momentarily increased the glide speed. 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 aircraft damage or pilot injury.

Title: 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.
