What was found

DURING PREFLIGHT, THE FLIGHT CREW NOTICED THAT THE RUDDER PEDALS WERE NO LONGER SYMMETRICAL COMPARED TO EACH OTHER. A MX TECH INSPECTED THE PILOT'S RT PEDAL (PN-DA4-2723-36-00) AND NOTICED THAT THE VERTICAL WEB THAT CONNECTS THE PEDAL TO THE BRAKE MASTER CYLINDER ROD HAD TORN AT THE WELDED INTERSECTION OF THE TUBE THAT IT IS WELDED TO. THE TEAR/CRACK IN THE HORIZ PEDAL PIVOT TUBE INDICATES A TORSIONAL FAILURE OF THAT TUBE.
