## Discrepancy

DURING SCHEDULED INSPECTION WE FOUND THAT BLEED AIR TUBE PN 6955300-9 CRACKED AT THE APU FIREWALL BULKHEAD TO BLEED AIR TUBE ASSEMBLY ATTACH FLANGE.  THE CRACK WAS TWO TO THREE INCHES LONG LOCATED AT THE WELD BETWEEN FLANGE & TUBE ASSEMBLY.  A NEW TUBE ASSEMBLY WAS ORDERED & INSTALLED.  WE HAVE FOUND THIS SAME DEFECT ON ACFT IN THE PAST.
