## Discrepancy

ABOUT 5 MINUTES INTO CRUISE THE FLIGHT CREW OBSERVED THE RT OIL PRESS DROPPING.  ALL OTHER ENG INDICATIONS WERE NORMAL.  AS OIL PRESS DROPPED INTO THE RED, PERFORMED A PRECAUTIONARY ENG SHUTDOWN IAW THE QRH, RAN THE APPROPRIATE CHECKLISTS, DECLARED AN EMER, PROCEEDED TO THE NEAREST SUITABLE FIELD & LANDED WITHOUT INCIDENT.
GAINED ACCESS TO THE RT ENG & CLEANED UP THE OIL RESIDUE.  REMOVED THE OIL FILTER & SENT IT OUT FOR ANALYSIS. FURTHER REMOVED THE CHIP DETECTOR & INSPECTED IT FOR CHIPS, NO CHIPS WERE FOUND.  INSTALLED A NEW OIL FILTER & ASSOCIATED O RINGS.  IN ADDITION, CHECKED THE OIL FILLER CAP FOR DAMAGED O RING & THE P TANK LINE FOR SECURITY, NO DEFECTS FOUND.  THE ENG WAS SERVICED WITH 1 QUART OF OIL.  RAN THE ACFT AT POWER FOR 5 MINUTES TO CHECK FOR LEAKS.  NO LEAKS WERE NOTED.
