## Discrepancy

PHX - FLT 731 - AIR TURN-BACK. AFTER ADDING CLIMB POWER, GOT NR 2 FIRE LIGHT AND BELL. SHUT DOWN NR 2 ENGINE PER CHECK LIST, BUT DID NOT USE THE FIRE BOTTLE SINCE THE LIGHT WENT OUT AFTER SHUTTING DOWN NR 2 ENGINE.  ON UPPER SIDE OF ENGINE, FOUND ON TIGHT HAND, ANTI-ICE VALVE FOUND SEAL BLOWN OUT, REMOVED AND REPLACED SEAL.
