## Discrepancy

RETURNED TO FIELD DUE TO LEFT BLEED OVERHEAT INDICATION. THE WING DUCT LEAK DETECTORS TS211 & TS212 WERE REPLACED. DURING TROUBLESHOOTING THE SENSOR THAT WAS CAUSING THE FAULT COULD NOT BE DETERMINED SO BOTH WERE REPLACED. THE REMOVED PARTS ARE NON-STOCK, NO FURTHER ANALYSIS. AS OF 09FEB06 THIS WAS THE ONLY ABNORMALITY REPORTED IN AMIS FOR CHAPTER 26.  AN 8-IN CRACK WAS FOUND IN THE DUCT CAUSING BLEED AIR LEAKAGE AND "BODY DUCT LEAK" EICAS MESSAGE TO APPEAR.  THE DUCT WAS REPLACED.
