## Discrepancy

CREW REPORTS TEMPORARY OIL PRESSURE LOSS ON APPROACH. ALL OTHER ENGINE INDICATIONS WERE NORMAL. UPON LANDING OIL PRESSURE RETURNED TO NORMAL. MECHANICS INSPECTED ENGINE. NO DEFECTS WERE NOTED. AVIONICS TECHNICIAN REPLACED THE OIL PRESSURE TRANSDUCER ELECTRICAL CONNECTOR WITH NEW P/N S2800-277. THIS CORRECTED THE INTERMITTENT OIL PRESSURE INDICATION ERRORS.
