## Discrepancy

DURING FLT AT APPROXIMATELY 2:00 AM, AIRCRAFT WAS ENROUTE WHEN THE PILOT NOTICED THAT THE LT ENGINE OIL PRESSURE WAS DECREASING.  THE PILOT ALSO NOTICED THAT THE LT EGT WAS CLIMBING.  THE PILOT ELECTED TO SHUT DOWN THE LT ENGINE AND RETURN AT THIS TIME.  NO EMERGENCY WAS DECLARED, AND THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE HAS BEEN DISPATCHED TO THE AIRCRAFT TO INVESTIGATE AT THIS TIME.
