## Discrepancy

DURING ANNUAL INSPECTION THE RIGHT WING AFT ATTACH FITTING OUTBOARD OF THE FUSELAGE AND AFT WING SPAR WERE FOUND TO EXHIBIT DISSIMILAR METAL CORROSION BETWEEN THE STEEL ATTACH FITTING AND THE REAR SPAR.  THE AFT SPAR WAS CORRODED TO THE POINT WHERE A CRACK HAD DEVELOPED IN THE REAR SPAR.  CRACK WAS NOT FOUND UNTIL STEEL ATTACH FITTING WAS REMOVED FOR HIDDEN DAMAGE INSPECTION.
