## Discrepancy

DURING PRE-FLIGHT, CREW NOTICED THAT THE RUDDER PEDAL APPEARED TO BE CROOKED, AT A DIFFERENT ANGLE RELATIVE TO THE OTHER PEDAL. MAINTENANCE PERSONNEL DISCOVERED THAT THE RUDDER PEDAL, P/N-DA4-2723-37-00 WAS CRACKED APPROXIMATELY 2 INCHES LONG WHERE THE BRAKE CYLINDER ACTUATING WEB IS WELDED TO THE HORIZONTAL TUBE. TWO OTHER AIRCRAFT IN THIS FLEET OF TEN HAD SIMILAR CRAKED PEDALS. IN TOTAL THERE WERE 4 CRACKED PEDALS.
