## Discrepancy

THE TRAILING EDGE EXTRUSIONS ON WINGS, FLAPS, AND FLIGHT CONTROLS WERE FOUND CORRODED AT EXPOSED EDGE WITH A FEW SMALL AREAS OF BULBED EDGE COMPLETELY GONE.  DISASSEMBLY OF TRAILING EDGES WAS REQUIRED TO DETERMINE THE EXTENT OF DAMAGE.  NO CORROSION WAS FOUND BEYOND THE 'BULBED' EXPOSED EDGE.  ALL EXTRUSIONS WERE REPLACED.
