## Discrepancy

DURING LAST 5 MINUTES OF FLIGHT THE AIRCRAFT WAS ON APPROACH, THE RIGHT ENGINE FIRE WARNING LIGHT CAME ON.  THE RIGHT ENGINE WAS SHUT DOWN AND THE FIRE BOTTLE WAS DISCHARGED.  AFTER LANDING, THE FIRE WARNING LIGHT WENT OUT.  NO FIRE WAS PRESENT ON THE ENGINE.  THE RIGHT FIRE WARNING CONTROL UNIT CONNECTOR P820 WAS FOUND TO HAVE AN INTERMITTENT SHORT CAUSING A FALSE FIRE INDICATION.  CONNECTOR P820 WAS REPLACED AND WIRES REROUTED TO PROVIDE BETTER STRAIN RELIEF ON THE BACK OF P820.
