## Discrepancy

THIS ACFT EXPERIENCED LOW OIL PRESSURE DURING TAKEOFF.  PILOT NOTICED LOW OIL PRESSURE INDICATION, LOW OIL PRESSURE WARNING, AND RESULTING ECU FAIL DISPLAYED ON G1000 PDF.  THE PILOT ABORTED TAKEOFF AND RETURNED TO PARKING.  DURING INSPECTION OF ACFT AND CORRESPONDENCE WITH ENGINES IT WAS DETERMINED THAT THE OIL SUMP BAFFLE MAY HAVE FAILED.  THE ACFT ENGINE OIL SUMP WAS REMOVED TO VISUALLY CONFIRM.  THE OIL SUMP BAFFLE WAS FOUND IN 5 PIECES AND HAD MULTIPLE CRACKS. ONE OF THE SMALLER PIECES GOT LODGED IN THE OIL PICK UP TUBE CAUSING LOW OIL PRESSURE AND ECU FAIL CODE BEING ACTIVATED.  ACFT AND ENGINE TIMES ARE ACTT: 1087.7 ETT: 1087.7 ESTIMATED CYCLES: 4350.8. THE ENGINE MFG HAS BEEN MADE AWARE OF THE FAILURE.  NO RECOMMENDATIONS AT THIS TIME. OIL SUMP BAFFLE REPLACED WITH ENGINE MFG LATEST PART REVISION.
