## Discrepancy

AIRCRAFT WAS NOT GROUNDED: ON RECALL DURING DESCENT, THE MASTER FIRE WARNING LIGHT ILLUMINATED AND WOULD NOT EXTINGUISH. DID FINALLY RESET. THEN, UPON ENGINE SHUTDOWN ILLUMINATED AGAIN, NO OTHER INDICATIONS. ACCOMPLISHED FIM PROCEDURE AND FIRE WARNING TEST PER FIM 26-10-00 OPS CHECKS OK. UNABLE TO DUPLICATE WRITE UP.
