## Discrepancy

(CAN) DURING MAINTENANCE TESTING FOR TROUBLESHOOTING OF AN AUTO-SHUTDOWN AT THE PREVIOUS FLIGHT, OIL SPRAY REPORTEDLY ORIGINATED FROM THE OIL COOLER AND CAUGHT FIRE.  THE FIRE WAS EXTINGUISHED USING EXTERNAL EXTINGUISHERS.  NO OBVIOUS DAMAGE WAS REPORTED AT THIS POINT. THE APU WILL BE REPLACED.
