Narrative

MY PAX AND I DEPARTED EHO; NC; VFR ENRTE TO IND; IN. CLBING TO 6500 FT AND LEVELING OUT; WE HEADED NW TO LEX; KY; WHERE WE INTENDED TO GET FUEL. ABOUT 35 NM SE OF LEX ARPT WE CONTACTED LEX APCH CTL. REPLY WAS A REQUEST TO LET APCH CTL KNOW WHEN WE WERE 15 NM FROM BLUEGRASS -- WE DID. WE CONTACTED THE LEX TWR. TWR SAID TO MAKE A L BASE FOR RWY 23; AND UPON TURNING FINAL WE CALLED TWR AND LET THEM KNOW WE WERE ON FINAL APCH. THEY ACKNOWLEDGED AND GAVE US A 'CLR TO LAND RWY 23.' WE CONTINUED ON DOWN THE APCH TO TOUCHDOWN WITH A TAILWHEEL LNDG IN THE CTR OF RWY 23. AS WE CONTINUED OUR ROLLOUT; THE AIRPLANE STARTED VEERING TO THE L; SO WE GAVE R RUDDER AND THEN THE AIRPLANE STARTED TO CORRECT BACK TO THE R UNTIL THE RUDDER WAS GOING SO SLOW THAT IT WAS NOT EFFECTIVE. THE AIRPLANE CONTINUED VEERING TO THE L UNTIL WE ENDED UP AT AN APPROX HDG OF 160 DEGS OR 70 DEGS TO THE L; WHEN THE R WHEEL ASSEMBLY BENT ABOUT 45 DEGS INWARD (BOTTOM OF TIRE TOWARDS FUSELAGE). THE ACFT CONTINUED FOR ABOUT 20-25 FT INTO THE GRASS AREA; IN WHICH TIME THE NOSE OF THE ACFT TURNED BACK TO THE R (70 DEGS) SAME AS RWY HDG. WX WAS CLR AND THE SUN WAS SETTING AT THE FAR END OF THE RWY. ENG WAS TURNED OFF AND CTL TWR WAS NOTIFIED OF THE INCIDENT; AND THAT THERE WERE NO INJURIES.
