## Discrepancy

SOON AFTER ESTABLISHING CRUISE FLIGHT AT FL400, CREW RECEIVED A “R ENG OIL PRESS LOW” CAS MESSAGE. THE MESSAGE POSTED AND CLEARED CONTINUOUSLY UNTIL ENGINE SHUTDOWN COMMAND, DUE TO OIL PRESSURE FLUCTUATING FROM 20 TO 35 PSI. CREW DESCENDED, RAN THE APPROPRIATE CHECKLIST AND DECLARED AN EMERGENCY. AN UNEVENTFUL LANDING WAS ACCOMPLISHED. MAINTENANCE FOUND THE OIL FILLER CAP O-RING (P/N: AS3209-222) DAMAGED, CAUSING THE OIL LOSS. A NEW O-RING WAS INSTALLED, AND GROUND MAINTENANCE RUNS PERFORMED, WITH NO DEFECTS NOTED. THE AIRCRAFT WAS RETURNED TO SERVICE.
