## Discrepancy

(CAN) FLIGHT CREW REPORTED THAT ANOTHER ACFT NOTICED, MORE SMOKE THAN NORMAL, COMING FROM THE APU TAIL PIPE ON SHUTDOWN.  NO OTHER INDICATIONS WERE REPORTED BY THE FLIGHT CREW. CRASH, FIRE, RESCUE ATTENDED THE ACFT ON THE TAXIWAY AND AFTER FINDING NO INFRA RED HOT SPOTS, CLEARED THE ACFT TO TAXI TO THE GATE.  MAINTENANCE DETERMINED THE APU TO BE AT FAULT AND WAS PLACED ON MEL AND SCHEDULED FOR REPLACEMENT.  MORE INFORMATION WILL BE PROVIDED WHEN DETAILS FROM THE TEARDOWN BECOME AVAILABLE.
