## Discrepancy

OWNER BROUGHT ACFT IN FOR LONGERON AND STIFFENER REPLACEMENT.  FOUND EXISTING LONGERONS WITH EXTREME INTERGRANULAR CORROSION AND EXFOLIATION.  SUBMITTER SUGGESTED THESE SHOULD BE INSPECTED CLOSELY ON TOP AND BOTTOM AT EACH ANNUAL INSPECTION.  IF CORROSION IS FOUND, REPLACE PARTS.  APPROXIMATELY 10-15 HOURS LABOR FOR EACH.
