## Discrepancy

ON ENGAGING AUTO PILOT A ON CLIMBOUT AT APPROXIMATELY 15500 AFTER A SECOND DELAY THE YOKE KICKED SLIGHTLY WE TURNED OFF THE AUTOPILOT, ENSURED WE WERE IN TRIM REENGAGED AND IT KICKED AGAIN. WHILE CONSULTING WITH THE FODO WE TRIED AUTOPILOT B AND CWS A AND B, ALL KICKED SHORTLY AFTER BEING ENGAGED. AFTER THE KICK THE AUTOPILOT OPERATED NORMALLY. GROUNDED - YES. C/W BITE CHECK OF DFCS, NO FAULTS NOTED, NO 30 DAY HISTORY A/C OK FOR SERVICE, BITE CHECK PER FIM B737-800 22-11 TASK 801.
