Narrative:

After T/D on landing, aircraft veered hard to the right and pulled aircraft off the runway, (runway 31 at fll) and on to the apron. The aircraft pulled with such force my first thought was that the right brake had frozen on. I used full left rudder, left brake and left aileron in addition to asymmetrical power to keep aircraft on the pavement. After the aircraft had come to a complete stop, I attempted a very slow taxi off the runway to which the tower advised that it appeard as though the right main gear was not extended. With that I shut down the aircraft on the runway. After asking for emergency equipment I exited the aircraft and looked it over. I found that the through bolt holding the torque links together had pulled through and the torque links had separated allowing the right main wheel assembly to rotate 180 degree within the right strut actually rolling in the opp direction causing the aircraft to veer to the right. The aircraft was later towed to the ramp where our mechanic inspected the aircraft and reinstalled broken torque link washers. He also inspected in accordance with the aircraft maintenance manual and found it to be out of airworthiness. There were no injuries, aircraft damage or runway or apron damage.

Title: ATX SMT EXPERIENCES RWY EXCURSION AT FLL DUE BROKEN TORQUE LINK ON RIGHT MAIN GEAR.

Narrative: AFTER T/D ON LNDG, ACFT VEERED HARD TO THE R AND PULLED ACFT OFF THE RWY, (RWY 31 AT FLL) AND ON TO THE APRON. THE ACFT PULLED WITH SUCH FORCE MY FIRST THOUGHT WAS THAT THE R BRAKE HAD FROZEN ON. I USED FULL L RUDDER, L BRAKE AND L AILERON IN ADDITION TO ASYMMETRICAL PWR TO KEEP ACFT ON THE PAVEMENT. AFTER THE ACFT HAD COME TO A COMPLETE STOP, I ATTEMPTED A VERY SLOW TAXI OFF THE RWY TO WHICH THE TWR ADVISED THAT IT APPEARD AS THOUGH THE R MAIN GEAR WAS NOT EXTENDED. WITH THAT I SHUT DOWN THE ACFT ON THE RWY. AFTER ASKING FOR EMER EQUIP I EXITED THE ACFT AND LOOKED IT OVER. I FOUND THAT THE THROUGH BOLT HOLDING THE TORQUE LINKS TOGETHER HAD PULLED THROUGH AND THE TORQUE LINKS HAD SEPARATED ALLOWING THE R MAIN WHEEL ASSEMBLY TO ROTATE 180 DEG WITHIN THE R STRUT ACTUALLY ROLLING IN THE OPP DIRECTION CAUSING THE ACFT TO VEER TO THE R. THE ACFT WAS LATER TOWED TO THE RAMP WHERE OUR MECH INSPECTED THE ACFT AND REINSTALLED BROKEN TORQUE LINK WASHERS. HE ALSO INSPECTED IN ACCORDANCE WITH THE ACFT MAINT MANUAL AND FOUND IT TO BE OUT OF AIRWORTHINESS. THERE WERE NO INJURIES, ACFT DAMAGE OR RWY OR APRON DAMAGE.
