## Discrepancy

PILOT REPORTED LOW OIL PRESSURE CAS ANNUNCIATION OBSERVED IN FLIGHT AND RETURNED FOR LANDING. PERFORMED POST FLIGHT INSPECTION, OIL QUANTITY WAS 6-7 QUARTS INDICATED (READ DIRECTLY AFTER SHUT DOWN). INSPECTED THE ENGINE FOR OIL LEAKS, NONE FOUND. INSPECTED OIL PRESSURE SENSOR AND OIL LINES, NO DEFECTS FOUND. REVIEWED ENGINE DATA AND CONFIRMED ERRATIC OIL PRESSURE INDICATION.
