## Discrepancy

DURING INITIAL DESCENT, FLIGHT CREW RECEIVED 'FIRE WARNING' INDICATION ON NR 1 ENGINE.  FLIGHT CREW PERFORMED ABNORMAL PROCEDURES:  SHUT DOWN NR 1 ENGINE, DISCHARGED NR 1 FIRE BOTTLE.  AT THAT TIME, FIRE WARNING INDICATION EXTINGUISHED.  ACFT LANDED WITHOUT FURTHER INCIDENT.  ACFT WAS INSPECTED, AND NO EVIDENCE OF FIRE NOTED.  CFDS REVIEWED AND NR 1 ENG A-LOOP WITH B-LOOP INOP WOULD CAUSE 'FIRE WARNING' INDICATION.  REPLACED 'A' RT REVERSER COWL FIRE LOOP, CLEARING FAULT ON A-LOOP.  ADDITIONALLY, CLEARED FAULTS ON B-LOOP BY REPLACING RT REVERSER COWL LOOP AND B-LOOP PYLON HARNESS.  BOTH SYSTEMS OPS CHK NORMAL DURING GROUND RUNS.  ACFT RETURNED TO SERVICE.  (X)
