## Discrepancy

(AUS) LT ENGINE FIRE WARNING. THE ENGINE WAS SHUT DOWN AND THE FIRE EXTINGUISHER ACTIVATED. SUBSEQUENT INSPECTION COULD FIND NO EVIDENCE OF FIRE. PRELIMINARY INVESTIGATION SUGGESTS AN ENGINEANTI-ICE BLEED AIR LEAK. FURTHER INVESTIGATION FOUND THE NUT ON THE ENGINE ANTI-ICE BLEED AIR TUBE HAD COME LOOSE. SUSPECT DUE TO INSUFFICIENT TIGHTENING DURING MAINTENANCE. PERSONNEL/MAINTENANCE ERROR.
