What was found

(CAN) THE RUDDER BELLCRANK WAS REMOVED AND CORROSION WAS FOUND ON THE SURFACE WHERE THE TORQUE TUBE CONNECTS. THERE WAS ALSO CORROSION FOUND ON THE BOLT HOLES. THE BELLCRANK AND BOLTS WERE REPLACED. SUBMITTER STATED THAT THIS AREA IS HARD TO INSPECT BECAUSE THE TORQUE TUBE COVERS THE BELLCRANK. THE SUBMITTER ALSO STATED THAT IT IS NOTEWORTHY THAT THIS AREA GETS EXPOSED TO THE ELEMENTS BECAUSE OF HOLES WHERE THE ELEVATOR TORQUE TUBES GO THROUGH THE TAIL CONE. THERE IS NO SCHEDULED MAINTENANCE TO REMOVE THIS BELLCRANK FOR INSPECTION.
