## Discrepancy

DURING ENGINE MAINTENANCE THAT REQUIRED THE REMOVAL OF THE OIL SUMP THE INTERNAL OIL SUMP BAFFLE (P/N 56G23399) WAS FOUND BADLY CRACKED (APPROX. 4" LONG) ON THE PAN SHEET, ALONGSIDE THE RIVET LINE FOR THE BACK BONE STIFFENER. ADDITIONALLY, 5 OF THE 6 MOUNTING HOLES WERE CRACKED, WITH 2 OF THEM BEING COMPLETELY BROKEN OUT IN A CIRCLE LEAVING THE BOLTS PROVIDING NO SUPPORT TO THE BAFFLE. UPON FURTHER EXAMINATION THERE WAS NO EVIDENCE OF THIS BAFFLE CONTACTING THE OIL SUMP AS REFERANCED IN LYCOMING SERVICE BULLETIN 579. THIS COMPONENT HAS 329.3 HOURS SINCE NEW.
