## Discrepancy

DURING ANNUAL INSPECTION IT WAS DISCOVERED THAT THERE WERE SEVERAL CORRODED AND CRACKED WING TRAILING EDGE RIBS IN BOTH LEFT AND RIGHT WINGS.  DURING REPLACEMENT OF THOSE RIBS AFTER OPENING UP THE WING SKIN THE CORROSION WAS OBSERVED TO BE MORE EXTENSIVE.  THIS RESULTED IN BOTH WINGS BEING DE-MATED FROM THE AIRCRAFT FOR REPAIR.
