## Discrepancy

AFT CARGO PIT MOLDED PANEL ON FWD WALL COVERING APU SUPPLY DUCT HAS EVIDENCE OF HEAT DAMAGE.  APU SUPPLY DUCT HEAT SHROUD DAMAGE WAS CAUSED BY CONTACT WITH THE APU SUPPLY DUCT AND INFERIOR DESIGN OF HEAT SHROUD.  THE HEAT SHROUD WAS REPLACED AND CONTACT WITH THE APU SUPPLY DUCT WAS ELIMINATED.  A MODIFIED HEAT SHROUD IS AVAILABLE AND WILL BE INSTALLED ON THIS AIRCRAFT IN THE FUTURE.
