## Discrepancy

DURING FLIGHT, LT ENGINE OIL TEMP NEARED RED LINE BUT DID NOT GO OVER.  NO OTHER ENGINE PARAMETERS HAD ANY DEFECT.  THE PILOT SHUTDOWN THE LT ENGINE AS A PRECAUTION AND LANDED WITH NO OTHER INCIDENTS.  MX REMOVED REAR SCAVANGE PUMP AND CLEANED OIL RESIDUE FROM JET TUBE AND FROM TRANSFER TUBE.  INSTALLED NEW SEALS AND GASKETS, INSPECTED FILTER WITH NO DEFECTS, AND CHANGED OIL.  GROUND RUNS AND 2.7 HOUR FLIGHT BACK TO AIRPORT  CONFIRMED OIL TEMP STAYED IN GREEN AND MATCHED THE RT ENGINE EXACTLY.  NO OTHER FAULTS FOUND.
