Narrative:

Approximately 2 miles out on left base to runway 14 at apf at 1000 ft MSL; the pilot flying in the left seat reported a close encounter with a drone. He estimated it at about 100 ft below us and not much more than a wingspan to our left. He described it as a quad copter with a body that had longitudinal stripes as if they were ribs on a wing. Subsequent online research revealed a drone meeting that description - a 'dji phantom 3 professional' drone. We're not sure that is what it was; but it had that look. He didn't have a lot of time to watch it as he was the pilot-flying; so as soon as he realized we were past it; he refocused on flying.while no evasive action was necessary in this situation; the drone we encountered was certainly between 800 and 1000 ft MSL well within the class D airspace at apf; and missed us by no more than 100 feet. We reported the encounter to naples ATCT and they advised at least a couple of aircraft who were following us on the approach.
