## Discrepancy

DEVELOPED OIL LEAK FROM LT ENGINE DURING RETURN FLIGHT.  OIL TEMP WAS HOLDING, BUT OIL PRESSURE HAD STARTED TO DECAY.  PILOT SHUT ENGINE DOWN AND FEATHERED AS A PRECAUTIONARY MEASURE.  FOUND PIN HOLE IN TURBOCHARGER OIL SUPPLY LINE AND REPLACED WITH NEW ON 1/21/03.  REMOVED OIL FILTER AND CHECKED FOR METAL CONTAMINATION, NONE FOUND.
