## Discrepancy

ENGINE OIL PRESSURE LIGHT ILLUMINATED SHORTLY AFTER TAKE OFF. LIGHT FLICKERED A COUPLE OF TIMES, THAN STAYED ILLUMINATED AS AIRCRAFT TURNED BACK TOWARDS BASE, THAN EXTINGUISHED ON DECENT INTO BASE. OIL PRESSURE LIGHT WAS NOT ILLUMINATED UPON SHUTDOWN. AIRCRAFT WAS INSPECTED, GROUND AND FLIGHT CHECKS PERFORMED AND UNABLE TO DUPLICATE CAUTION LIGHT. OIL PRESSURE GAUGE SHOWS NORMAL INDICATIONS
