## Discrepancy

DURING MAINTENANCE BASE INSPECTION FOUND THE SERVICE DOOR CENTER SILL CORRODED. THE AIRCRAFT WAS REMOVED FROM SERVICE.  THE SERVICE DOOR CENTER SILL NUT PLATE WAS REPAIRED IAW EMB SRM 53-21-02, 51-40-02 AND CPM 51-21-06.  THE CORROSION LEVEL WAS RECORDED AS A LEVEL ONE CORROSION ISSUE, HOWEVER THE REPAIR WAS CONSIDERED TO BE A MAJOR REPAIR. THE AIRCRAFT WAS RETURNED TO SERVICE.
