## Discrepancy

AIRCRAFT WAS GROUNDED.  FLIGHT CREW REPORTED A DIRTY SCOCK, MUSTY ODOR COMING FROM THE AC VENTS WHEN APU BLEED WAS TURNED ON WHILE BOARDING THE ACFT AT THE GATE.  MAINTENANCE FOUND OIL IN THE APU PLENUM AND REPLACED THE APU OIL COOLER IAW 49-91-44,  THE APU OIL COOLING FAN IAW AMM 49-52-51.  A SATISFACTORY LEAK AND OPS CHECK WAS ACCOMPLISHED WITH NO ODORS BEING NOTED.  SEE AALA201607199013 FOR ADDITIONAL PART.
