## Discrepancy

CYAN MESSAGES "AP FAIL L-R AND YD FAIL A-B" IN FLIGHT AT FL 370.  AP WOULD NOT RE-ENGAGE. WHEN AP DISCONNECTED, A SLIGHT BUMP WAS FELT IN THE ROLL / AILERONS OF CONTROL WHEEL.  COULD NOT DUPLICATE FAILURE ON THE GROUND SO PROCEEDED WITH RUDDER SERVO CHARGE.  REMOVED AND REPLACED RUDDER SERVO IAW MM 22-10-00. FOUND SERVERAL PINS PUSHED BACK IN CONNECTOR TO SERVO THAT MAY HAVE CONTRIBUTED TO FAILURE.  RESEATED PINS. OPERATIONAL CHECK OF AUTOPILOT SYSTEM WAS GOOD.  RUDDER SERVO CHECKS GOOD.
