## Discrepancy

FALSE ENGINE FIRE LIGHT.  THIS IS AN INTERMITTENT DISCREPANCY; WE HAVE ALREADY SENT A SDR EARLIER THIS MONTH.  COULD NOT DUPLICATE.  CHECKED FIRE LOOPS, WIRING, CHECKED FOR BLEED AIR LEAKS, GROUND RAN, AND SWAPPED ENGINE FIRE DETECT CONTROL.  (SUSPECT ENGINE EXHAUST FIRE LOOP) WE THINK IT IS MAKING CONTINUITY PREMATURELY.  PULLED BACK THRUST LEVER, LIGHT EXTINGUISHED, LANDED.  (K)
