## Discrepancy

UPON LANDING GEAR EXTENSION, A WHEEL WELL FIRE WARNING EICAS MESSAGE ILLUMINATED.  FIRE INDICATION APPEARED TO CORRESPOND WITH ACTUATION OF THE SPEED BRAKES.  THE FLIGHT CONTINUED AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE WHEEL WELL FIRE DETECTION LOOPS WITH SERVICEABLE UNITS.  SYSTEM OPERATIONAL TESTS WERE SATISFACTORY.
