FLEW TO KLUK ABOUT 0700. A/C SAT ON THE RAMP UNTIL ABOUT 1530, ABOUT WHICH TIME WE DEPARTED FOR KGRR. APPROX 10 MINUTES INTO OUR FLIGHT APPROACHING FL250 WITH A CLEARANCE TO CLIMB HIGHER. ABOUT THIS TIME AND ALTITUDE, WE RECEIVED AN AMBER AP AIL MISTRIM EICAS MESSAGE TO WHICH THE 1ST OFFICER RESPONDED TO BY HOLDING THE CONTROLS AND DISCONNECTING THE AUTO PILOT. AT THAT TIME, HE SAID THAT HE WAS UNABLE TO CONTROL AIRCRAFT ROLL NORMALLY, DUE TO THE AILERONS BEING JAMMED OR FROZEN. CAPTAIN THEN TOOK CONTROL OF THE AIRCRAFT, CONTROLLED IT WITH RUDDER AND THRUST INITIALLY (MOSTLY RUDDER, WHICH WORKED GREAT), AND THEN PULLED THE ROLL DISC LEVER PER THE AFM.
