## Discrepancy

IN C/W CESSNA SI MEB 99-10, ULTRASONIC NDT INSPECTION FOUND ENGINE BEAMS AND CANTED BULKHEAD CORRODED BEYOND THE MATERIALS ACCEPTABLE THICKNESS.  CAUSE OF CORROSION WAS FROM LEAKING EXHAUST AND HIGH TURBO TEMPERATURE.  RECOMMEND A STAINLESS STEEL CHANNEL.  TO COVER ENGINE BEAMS AFTER NDT INSPECTION, RECOMMEND REPLACEMENT OF CANTED BULKHEAD OR STAINLESS STEEL DOUBLERS AROUND EXHAUST AUGMENTER TUBES RUNNING THROUGH THE CANTED BULKHEAD.
