## Discrepancy

DURING APPROACH TO MEMPHIS, THE L FIRE FAIL, L JETOVHT FAIL, APU FAIL, R FIRE FAIL, AND R JETOVHT FAIL CAUTION MESSAGES ILLUMINATED.  APPROXIMATELY 20 SECONDS LATER, THE L JETOVHT WARNIGN MESSAGE ILLUMINATED INTERMITTENTLY, FOLLOWED BY THE L ENG FIRE AND APU FIRE WARNING MESSAGES.  THE APU WAS NOT RUNNING AT THE TIME.  EMERGENCY PROCEDURES WERE CARRIED OUT, LEFT ENGINE WAS SHUT DOWN AND FIRE BOTTLE DISCHARGED.  APU FIRE BOTTLE WAS ALSO DISCHARGED.  LANDING WAS OTHERWISE UNEVENTFUL.  DURING T/S, MX FOUND THE FIRE DETECTECTION CONTROL UNIT LOCATED UNDER LEFT CONSOLE SHORTED AND CONTAMINATED WITH A LIQUID (COFFEE).  A NEW CONTROLLER, ENGINE FIRE BOTTLE AND APU FIRE BOTTLE WERE INSTALLED.
