## Discrepancy

THE CTR WING FUEL CELL ACCESS WAS FOUND TO HAVE CORROSION ON THE FLANGE. THIS FLANGE IS HIDDEN BY THE FUEL CELL COVER AND THE DAMAGE IS NOT READILY VISIBLE DURING NORMAL MX.  THIS AREA HAS A HISTORY OF WATER/ CONDENSATION  INGRESS AND SHOULD BE THOROUGHLY INSPECTED WHEN WATER IS FOUND POOLING IN THE COVER BAY. THE DAMAGE REPORT HAS BEEN FORWARDED TO MFG FOR REPAIR INSTRUCTIONS.
