## Discrepancy

(CAN) THE AIRCRAFT WAS DEPARTING WHEN THE CREW EXPERIENCED AN APU FIRE INDICATION. THEY FOLLOWED PROCEDURES INCLUDING DISCHARGING THE EXTINGUISHER BOTTLE THEN RETURNED TO BASE. THE APU WAS INSPECTED BY MAINTENANCE AND THERE WAS NO INDICATION OF FIRE DAMAGE. THE AIRCRAFT WAS DISPATCHED WITH THE APU ON MEL DUE TO THE DISCHARGED BOTTLE.
