## Discrepancy

(CAN) DURING TROUBLESHOOTING AN APU FAULT , IT WAS DISCOVERED THAT THE APU FIRE BOTTLE HAD DISCHARGED . WHEN THE BOTTLE DISCHARGED THE OUTLET VALVE'S FLANGE NUT BROKE INTO 3 PIECES AND THE FIRE BOTTLE SUPPORT BRACKET WAS BENT, WHICH CAUSED THE FIRE BOTTLE TO SEPARATE FROM THE OUTLET VALVE. THE FIRE BOTTLE ASSY WAS REMOVED AND NEW ASSY INSTALLED.
