## Discrepancy

DURING ROUTINE 100 HOUR INSPECTION, THE LEFT TAILPIPE WAS FOUND TO HAVE BURNT OIL ON IT. THE TAILPIPE WAS REMOVED FOR FURTHER INVESTIGATION AND BURNT OIL WAS VISIBLE IN THE TURBOCHARGER AROUND THE TURBINE BEARING. DUE TO THIS OIL LEAK THE TURBOCHARGER WAS REMOVED AND REPLACED WITH SERVICEABLE.
