## Discrepancy

ON LANDING ROLLOUT THE PILOT NOTICED THAT THE TAIL WHEEL HAD COLLAPSED AND THE KEEL AT THE AFT STEP WAS DRAGGING ON THE RUNWAY.  THE PILOT TAXIED CLEAR OF THE RUNWAY.  MAINTENANCE FOUND THAT A BOLT INSTALLED AT THE TAIL WHEEL LOCK ACTUATOR WAS CATCHING ON THE ASSISTOR SPRING.  AFTER ADJUSTMENTS WERE MADE THE TAIL WHEEL RETRACT AND EXTENSION OPERATED NORMALLY.  THERE WAS SOME KEEL DAMAGE ON BOTTOM OF KEEL APPARENTLY ISOLATED TO KEEL STRIP ITSELF.
