## Discrepancy

DURING ANNUAL INSPECTION, FOUND TURBO SUPPORT MOUNT UPPER FOOT CRACKED AND LOWER FOOT AREA WHICH IS CLOSER TO TURBO EXHAUST SCROLL VERY RUSTY.  REPLACED WITH NEW MOUNT WHICH HAS IMPROVED PLATING PROCESS.  AIRCRAFT HAS BEEN MODIFIED IAW STC SA5691MM AND HAS A TSIO520 SERIES INSTALLED.  THE PROXIMITY OF THE TURBOCHARGER TO THE ENGINE MOUNT AND TURBO SUPPORT TUBES REQUIRED CONSTANT INSPECTIONS FOR HEAT DAMAGED COMPONENTS.
