## Discrepancy

AFTER DEPARTURE, THE FLIGHT CREW RECOGNIZED A LOW OIL PRESSURE INDICATION ON THE LEFT ENGINE. WHILE ABORTING THE FLIGHT AND RETURNING TO DEPARTURE, THE CAPTAIN ASKED FOR THE ABNORMAL CHECKLIST AND COPILOT RETRIEVED THE APPROPRIATE CHECKLIST AND COMPLETED THE CHECKLIST. THE CHECKLIST CALLS FOR A PRECAUTIONARY ENGINE SHUTDOWN, IN WHICH THE FLIGHT CREW PERFORMED. THE AIRCRAFT CONTINUED UNEVENTFULLY. MAINTENANCE WAS NOTIFIED AND AFTER FURTHER INSPECTION IT WAS FOUND THAT THE LEFT ENGINE OIL PRESSURE GUAGE TRANSDUCER WAS AT FAULT. THE AIRCRAFT WAS TAKEN OUT OF SERVICE UNTIL THE TRANSDUCER WAS REPLACED AND THE AIRCRAFT WAS SIGNED OFF RETURNED TO SERVICE.
