## Discrepancy

DURING THE ACCOMPLISHMENT OF SB190-57-0056 WING LOWER SKIN REINFORCEMENTS, THE PYLON WERE REMOVED FOR ACCESS. DURING THE INSPECTION BEFORE THE PYLON INSTALLATION, THE CUSTOMER FOUND THE RH PYLON SUPPORT LUGS (INBOARD AND OUTBOARD) WITH BUSHINGS FRETTING. AFTER BUSHING REMOVAL FOR REPLACEMENT, THE LUG BORES WERE FOUND WITH SMALL WEAR. DUE TO THIS FACT, THE CUSTOMER REAMED TILL DAMAGE REMOVAL. THE DISCREPANCIE WAS REPORTED TO EMB AND WAS REPAIRED IAW ETD2025-190-905321 AND  COO-EO-2025-22132.
