What was found
(CAN AFTER PERFORMING A BRIEF GND RUN & SHUTDOWN WITH NO INDICATION OF ANYTHING WRONG, THE PILOT & ENGINEER WERE WALKING AROUND THE TAIL OF THE ACFT, THEY NOTICED THE RUDDERS AT FULL RT DEFLECTION, THE PILOT HAD LEFT THE PEDALS IN THE NEUTRAL POSITION. THIS PROMPTED THEM TO CONFIRM & UPON FURTHER INVESTIGATION A THREADED ROD END BEARING WAS FOUND BROKEN DIRECTLY BEHIND THE JAM NUT AT THE PEDAL INPUT TO THE PC-60F.
