## Discrepancy

WHILE IN CRUISE FLIGHT, THE PILOT LOOKED AT THE ENGINE OIL PRESSURE GAUGE AND SAW NO INSTRUMENT INDICATION.  LANDED WITHOUT INCIDENT.   MECHANIC TROUBLESHOT THE ENGINE OIL PRESSURE TRANSDUCER SYSTEM FOR THE INDICATION  AND CLEANED THE CONNECTOR PLUG WITH NO OBVIOUS DEFECTS TO WIRING AND REINSTALLED.  WITH SUBSEQUENT OPERATIONS CHECK,  NO DEFECTS WERE NOTED AND THE ACFT WAS PLACED BACK INTO SERVICE.
