## Discrepancy

WHEN WE ENGAGED THE AUTOPILOT, THE AIRCRAFT ROLLED SHARPLY TO THE RIGHT AND DISENGAGED. WE RE-STABILIZED THE AIRCRAFT AND ENGAGED THE AUTOPILOT A 2ND TIME. IT ROLLED SHARPLY TO THE RIGHT AGAIN. WE CONTACTED FODO AND ALL DECIDED TO RETURN TO SEA INSTEAD OF CONTINUING TO OGG. GROUNDED - YES. RRMOVED AND INSTALLED NEW FFC B. REF B737-800 AMM 22-11-33/401.
