## Discrepancy

GALLEY FLOOR STRUCTURE FOUND CORRODED WHEN GALLEY WAS REMOVED FOR OTHER MAINTENANCE. REPAIRED FLOORBEAM IAW DRAWING 4182527-01 AND SRM 51-10-51. NEW MOISTURE PROTECTIVE BARRIER APPLIED UNDERNEATH FLOORING MATERIAL AND THE FLOORBOARDS.  THE CORROSION APPEARS TO HAVE BEEN CAUSED BY THE LACK OF A MOISTURE PROTECTIVE BARRIER BETWEEN THE FLOORING MATERIAL AND THE UNDERLYING STRUCTURE WHICH ALLOWED MOISTURE/CONTAMINANTS TO GET UNDER THE FLOOR.
