## Discrepancy

(CAN) PILOT REPORTED INCREASED START TEMPERATURE. ON RUN-UP IT WAS DISCOVERED THAT THE LARGE AIR LINE BETWEEN THE ENGINE COMPRESSOR AND THE FIREWALL WAS LEAKING AIR FROM THE FLEXIBLE BRAID SECTION. ENGINE WAS SHUT DOWN AND THE LINE WAS REPLACED. THE LEAK IS NOT DETECTABLE BY VISUAL INSPECTION.
