## Discrepancy

RH ENGINE FIRE INDICATION ON APPROACH TO LAND.  USED BOTH FIRE BOTTLES AND SHUT DOWN THE ENGINE, AND THE LIGHT REMAINED ILLUMINATED.  AFTER INSPECTION, NO EVIDENCE OF FIRE WAS FOUND.  INSPECTION DETERMINED THE CAUSE WAS A CHAFFED ENGINE FIRE DETECTION LOOP RUBBING ON AN ENGINE BLEED AIR LINE.  R&R FIRE DETECTION LOOP AND OPS CHECK GOOD.
