## Discrepancy

DURING HEAVY MAINTENANCE: CPCP FINDING: CORROSION ON FLOOR STRUCTURE BEAM, BETWEEN FR 12 AND FR 14 AT Y=250 RH; ALL WORK ACCOMPLISHED ON TOMEX NR 00280,  CORROSION ON FLOOR STRUCTURE BEAM, BETWEEN FR 12 AND FR 14 AT Y=250 RH WAS REMOVED, AND EVALUATED, THEREFORE IT IS OUT OF LIMITS. THE FLOOR STRUCTURE BEAM WAS REPLACED FOR ONE NEW PER EMB190 SRM 51-41-01, SRM 51-41-02, SRM 51-43-04, AND SRM 51-43-03. NO SPECIFIC OR ADDITIONAL INSPECTIONS ARE NECESSARY.
