AFTER INSPECTION OF THE COMPLETE AILERON SYSTEM, IT IS SUSPECTED THAT FOD HAD COME IN CONTACT BETWEEN THE AFT AILERON PULLEY AND CABLE ASSEMBLY.  THE AILERON BALANCE CABLE, AFT PULLEY, FORWARD AND AFT AILERON CABLE ASSEMBLIES WERE REPLACED.  THE CABLES WERE RIGGED AND TRAVELS CHECKED IAW MM.  THE ENTIRE AC BELLY WAS INSPECTED AND CLEANED FOR ANY FOD.  THE AIRCRAFT WAS TEST FLOWN WITH ALL FLIGHT CONTROL OPERATIONS NORMAL.  (GL11200414316)
