## Discrepancy

DURING CLIMB THE FLIGHT CREW GOT A MESSAGE ON EICAS "RUDDER SYSTEM 1 & 2 INOP" "YAW DAMPENER INOP".   AIRCRAFT RETURNED TO IAD.  MAINTENANCE INSPECTED AND SWAPPED RUDDER PRESSURE SWITCHES NR 1 WITH NR 2 FOR TROUBLESHOOTING AND THEN REMOVED AND REPLACED NR 1 PRESSURE SWITCH.  MAINTENANCE PERFORMED A LEAK AND OPS CHECK OF THE AUTO PILOT AND YAW DAMPENER SYSTEMS.  OPS AND LEAK CHECKS WERE GOOD.
