## Discrepancy

ONE HOUR INTO FLIGHT, THE RIGHT ENGINE 'ENGINE OIL PRESS LOW' LIGHT CAME ON.  ENGINE THRUST WAS REDUCED AND EMERGENCY CHECK LIST WAS ACCOMPLISHED.  AFTER 2 MINUTES, THE RIGHT ENGINE WAS SHUT DOWN AND AN UNEVENTFUL SINGLE ENGINE LANDING WAS MADE AT KLAS.  UPON INSPECTION, A FAILED HYDRAULIC PUMP ACCESSORY GEARBOX SHAFT SEAL WAS FOUND THAT CAUSED LOSS OF OIL.  RECURRENCE CONTROL:  NONE.  ISOLATED FAILURE.
