## Discrepancy

ON ARRIVAL, SOME DISCOLORATION, MISSING PAINT WAS NOTED ON THE RT ENGINE PYLON. ON FURTHER INVESTIGATION IT WAS FOUND THAT THE PRE-COOLER HAD RUPTURED IN THE PYLON CAUSING SEVERE HEAT DAMAGE TO THE SURROUNDING STRUCTURE AND PYLON, FUSELAGE SKINS.  IT WAS DETERMINED BY ENGINEERING THAT THE ENGINE SUPPORT BEAMS AND MOUNTS HAD NOT SUFFERED ANY DAMAGE AND THAT THE ACFT WOULD BE SAFE FOR A 1 TIME FERRY TO FOR REPAIRS. THE ONLY ANOMALY NOTED BY THE FLIGHT CREW WAS AN ITT SPLIT OF 50 DEGREES. THERE IS NO OVERHEAT DETECTORS IN THE PYLONS ON THE CJ2.
