LEFT ENGINE FIRE WARNING LIGHT CAME ON DURING APPROACH TO LRD.  CREW SHUT DOWN ENGINE AND SELECTED FIRE BOTTLE TO LEFT ENGINE.  LATER INVESTIGATION REVEALED NO EVIDENCE OF FIRE FROM THE LEFT ENGINE AREA.  FURTHER INVESTIGATION FOUND 1 OF 3 SECTIONS OF LEFT ENGINE FIRE LOOP LOCATED AT THE FIRE WALL WAS SHORTED BEYOND MAINTENANCE MANUAL LIMITS.  REPLACED FIRE LOOP SECTION WITH SERVICEABLE LOOP, REPLACED FIRE BOTTLE WITH SERVICEABLE, OVERHAULED BOTTLE.  ALL WORK PERFORMED IN ACCORDANCE WITH THE LEARJET 35/36/35A/36A MAINTENANCE MANUAL.
