Narrative:
On mar/xx/93 I was flying, alone, an small aircraft, a 2-TANDEM seat single engine tail dragger airplane with heel brakes. After a series of takeoffs and lndgs at tri-county airport, on my last landing, during the landing roll after touchdown on runway 9 there was no tail wheel control after attempting to steer/control it with rudder pressure. The airplane immediately traveled off north side of runway and stopped in soft dirt. On that particular airplane, whenever the rudder travels in excess of 15 degrees -- its limit is 25 degrees. It can release the tailwheel from its longitudinal direction with the airplane and travel in any free wheeling direction on a ground surface. Although I tried to control it with rudder pressure, it had no effect on the direction of the tail wheel. Also, since my aircraft brake experience has been in airplanes with toe brakes (12329.7 hours) and this airplane has heel brakes, I failed to respond quickly enough to brake to a stop prior to leaving the runway. Natural reflexes responded to toe brake usage.

Title: PLT OF AN SMA CONVENTIONAL GEAR ACFT LOST DIRECTIONAL CTL DURING LNDG ROLLOUT AND DRIFTED OFF SIDE OF RWY.
Narrative: ON MAR/XX/93 I WAS FLYING, ALONE, AN SMA, A 2-TANDEM SEAT SINGLE ENG TAIL DRAGGER AIRPLANE WITH HEEL BRAKES. AFTER A SERIES OF TKOFS AND LNDGS AT TRI-COUNTY ARPT, ON MY LAST LNDG, DURING THE LNDG ROLL AFTER TOUCHDOWN ON RWY 9 THERE WAS NO TAIL WHEEL CTL AFTER ATTEMPTING TO STEER/CTL IT WITH RUDDER PRESSURE. THE AIRPLANE IMMEDIATELY TRAVELED OFF N SIDE OF RWY AND STOPPED IN SOFT DIRT. ON THAT PARTICULAR AIRPLANE, WHENEVER THE RUDDER TRAVELS IN EXCESS OF 15 DEGS -- ITS LIMIT IS 25 DEGS. IT CAN RELEASE THE TAILWHEEL FROM ITS LONGITUDINAL DIRECTION WITH THE AIRPLANE AND TRAVEL IN ANY FREE WHEELING DIRECTION ON A GND SURFACE. ALTHOUGH I TRIED TO CTL IT WITH RUDDER PRESSURE, IT HAD NO EFFECT ON THE DIRECTION OF THE TAIL WHEEL. ALSO, SINCE MY ACFT BRAKE EXPERIENCE HAS BEEN IN AIRPLANES WITH TOE BRAKES (12329.7 HRS) AND THIS AIRPLANE HAS HEEL BRAKES, I FAILED TO RESPOND QUICKLY ENOUGH TO BRAKE TO A STOP PRIOR TO LEAVING THE RWY. NATURAL REFLEXES RESPONDED TO TOE BRAKE USAGE.
