## Discrepancy

AIRCRAFT WAS GROUNDED: ON CLIMB OUT, FLIGHT ATTENDANT CALLED THE FLIGHT DECK AND REPORTED THAT SEVERAL PASSENGERS WERE REPORTING FUMES AND A MUSTY ODOR IN THE CABIN.

MAINTENANCE REPLACED THE APU COOLING FAN AND THE APU OIL COOLER (AALA202204074072), A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ODORS BEING NOTED.
