Narrative:

The aircraft had been boarded with nearly all passenger. Myself and another flight attendant were in the aft galley of the aircraft. We noticed a burning smell, looked into the cabin and saw smoke. We immediately called the cockpit, they advised us they'd turn on the extraction fans, but in a very short time the smoke became worse. We advised the captain again and decided it would be best to have passenger deplane back into terminal. Our #1 flight attendant made the announcements and all passenger deplaned calmly. Myself and the other flight attendant in the aft opened the rear emergency doors to let air in. Maintenance came on board and fixed the problem. Evidently the APU cooling fan burnt out causing the smoke. The flight was delayed 71 mins, but continued on with no further incident.
