## Discrepancy

ON CLIMB OUT, ENGINE OIL FILTER CAUTION LIGHT ILLUMINATED. PROCEDURE IS LAND AS SOON AS PRACTICAL. I WAS OVER A NUMBER OF BUILDING AND ALREADY HEADED FOR THE AIRPORT AND CONTINUED TO LAND ON THE RAMP. INSPECTION AFTER SHUTDOWN SHOWED APPROPRIATE ENGINE OIL LEVEL, NO LEAKS AND NO IMPENDING BYPASS BUTTON POPPED.  FOLLOWED PMIC PROCESS, WROTE UP DISCREPANCY AND CONTACTED ALL THE APPROPRIATE PEOPLE. REMOVED AND REPLACED SCAVENGE OIL FILTER
