## Discrepancy

DURING SID 57-10-16 INSPECTION, 3 AREAS OF CORROSION WERE IDENTIFIED ON THE RIGHT SPAR STRAP OF N402VN. THESE AREAS ARE LOCATED ON THE OUTBOARD END OF THE STRAP BETWEEN APPROXIMATE WING STATIONS, 145.87-155.62, AND ARE BEYOND LIMITS FOR REPAIR AS OUTLINED IN SID 57-10-16. THIS STRAP HAS BEEN REPLACED USING NEW PARTS.
