## Discrepancy

(CAN) THE AIRCRAFT WAS CLIMBING OUT OF VANCOUVER WHEN THE APU DID AN AUTO SHUT DOWN AND THE APU FIRE HANDLE ILLUMINATED. THE FIRE HANDLE WAS PULLED BUT THE BOTTLE WAS NOT DISCHARGED DUE TO THE FIRE INDICATION GOING OUT. THE AIRCRAFT RETURNED TO VANCOUVER WHERE THE APU AREA WAS INSPECTED AND NO EVIDENCE OF A FIRE WAS DISCOVERED. THE APU WAS PLACED ON MEL AND THE AIRCRAFT WAS RELEASED TO SERVICE. FURTHER INVESTIGATION LATER IN THE DAY FOUND THAT THERE WAS METAL FRAGMENTS FOUND IN THE INTAKE OF THE APU AND THE APU WAS REMOVED FROMTHE AIRCRAFT. IT WILL BE RETURNED TO THE OVERHAUL FACILITY FOR DISASSEMBLY AND REPAIR.
