AFTER A "HEADS UP" FROM ANOTHER OPERATOR, THE RUDDER TORQUE TUBE PN 2633066-3 WAS INSPECTED FOR CORROSION. INITIAL INSP REAVEALED CORROSION ON MUCH OF THE EXPOSED SURFACES OF THE FRAME, PN 2633014-1 AND SUPPORT PLATE PN 2633017-1 WHICH ARE LOCATED INSIDE THE RUDDER. THE LOWER PORTION OF THE TUBE AND BELLCRANK EXTENDING OUTSIDE THE RUDDER WAS COATED WITH FINISH PAINT AND WAS NOT AFFECTED. THE TORQUE TUBE ASSY WAS REMOVED FROM THE RUDDER AND CORROSION WAS FOUND ON ALL THE EXPOSED SURFACES AS WELL AS THE FAY SURFACES. THERE WAS MILD CORROSION INSIDE THE TUBE NEAR EACH END. THE PRIMER APPLIED TO THESE SURFACES APPEARS TO BE THIN AND NOT THE SAME QUALITY AS PRIMER ON ADJACENT ALUMINUM SKINS AND RIBS. ALL ORIGINAL PAINT WAS REMOVED FROM TORQUE TUBE ASSY AND MINIMAL DAMAGE WAS NOTED. PART WAS RECOATED WITH EPOXY PRIMER AND REINSTALLED USING PROCEDURES OUTLINED IN CAB06-2. CAB06-2 COVERS THIS SAME SUBJECT BUT DOES NOT INCLUDE THIS S/N ACFT. THIS ACFT IS EQUIPPED WITH TKS ANTI-ICE SYS AND TKS FLUID WAS FOUND THROUGH THIS AREA INCLUDING INSIDE THE RUDDER AND BETWEEN FAY SURFACES. ALSO ALL 4 FLAP AFT BELLCRANKS AND LT FWD BELLCRANK WERE IN SIMILAR CONDITION AND HAD TO BE STRIPPED AND REPAINTED.

RT MLG TRUNNION WAS FOUND CHAFED AND WORN BEYOND LIMIT BY CONTACT WITH MLG FAIRING PN 2641018-28. WEAR LIMIT IS ESTABLISHED IN CAB05-17 WHICH ADDRESSES THIS CONDITION IN EARLIER SN AIRPLANES BUT DOES NOT COVER THIS AIRPLANE MFG 6/5/08. CONDITION WAS NOT DETECTED UNTIL MLG WAS REMOVED FOR SCHEDULED CORROSION INSP ALTHOUGH THE AREA IS EASILY INSPECTED WITH THE FAIRING REMOVED. AIRPLANE CAME FROM FACTORY WITH NO RUB STRIP ON THE TRUNNION OR RUBBER MOLDING ON THE LOWER EDGE OF THE FAIRING AS CALLED FOR IN CAB05-17. THIS AREA SHOULD BE INSPECTED ANY TIME THE FAIRING IS REMOVED ON EITHER SIDE.
