An American Airlines Airbus A321-200, registration N103NN performing flight AA-9240 from Phoenix,AZ to New York JFK,NY (USA), was climbing out of Phoenix when the crew stopped the climb at about 8500 feet due to smoke in the cabin and returned to Phoenix for a safe landing about 20 minutes after departure.

The flight was the continuation of the previous day’s flight AA-10, which had diverted due to the same problem, see Incident: American A321 near Phoenix on Jan 2nd 2019, smoke in cabin.

The airline reported a similiar problem occurred again, an electrical odour from the chiller occurred although maintenance had worked to resolve the problem. A faulty fan is being suspectede as cause of the odour.
