## Discrepancy

(CREW NARRATIVE) WE DEPARTED THIS EARLY MORNING TO PWA.  SHORTLY AFTER DEPARTURE, 325ER’S RIGHT ENGINE BEGAN SLOWLY LOSING OIL PRESSURE AND OIL TEMP SLOWLY INCREASED.  15 MINUTES INTO THE FLIGHT, RIGHT ENGINE OIL PRESSURE HAD GRADUALLY DROPPED FROM 65PSI AT TAKEOFF TO 13 PSI.  WHEN OIL PRESSURE GOT AS LOW AS 25PSI, WE DETERMINED THE BEST COURSE OF ACTION AT THAT POINT WAS TO PREFORM A PRECAUTIONARY ENGINE SHUTDOWN AND RETURN TO BASE.  RED OIL PRESS ANNUNCIATOR LIGHT CAME ON AS IT SHOULD WHEN OIL PRESSURE FELL BELOW 20PSI.  BY THE TIME WE ACTUALLY MOVED RIGHT THRUST LEVER TO CUTOFF, OIL PRESSURE READ 13PSI.  (MAINTENANCE NARRATIVE): CLEANED ENGINE OF RESIDUAL OIL.  BAGGED OIL DRIP LINES AND RAN ENGINE ON GROUND.  NOTED OIL LEAK FROM ENGINE HYDRAULIC PUMP SEAL.  ORDERED SEAL AOG AND CALLED WEST STAR FOR OUTSIDE VENDOR ASSISTANCE (SCHEDULED FOR MONDAY 2/16/26 ARRIVAL)
