B757 CREW HAD A #2 ENG FIRE WARNING IN ZMA CLASS A.

Narrative

DURING CLB; R ENG FIRE WARNING ILLUMINATED. ADVISED ATC OF EMER AND REQUESTED RETURN TO MIA. NOTIFIED COMPANY OPS AND ACCOMPLISHED QRH PROCS; PERFORMED SINGLE ENG LNDG ON RWY 27L. AFTER TURNING OFF RWY; RESCUE FIRE SUPPORT PERSONNEL OBSERVED NO SIGNS OF SMOKE/FIRE ON THE R ENG. SUSPECT FALSE INDICATION AS FIRE WARNING REMAINED AND ILLUMINATED THROUGHOUT THE FLT AND AFTER SECURING ACFT AT THE GATE. SUPPLEMENTAL INFO FROM ACN 598029: CLBING THROUGH FL220 OVER FT LAUDERDALE; FL; WE RECEIVED A #2 ENG FIRE WARNING. WHILE DSNDING FROM FL220 TO 10000 FT; TWICE THE ENG FIRE WARNING WENT OUT FOR A WHILE THEN WOULD COME BACK ON; THEN OUT AGAIN. AT 3000 FT; JUST E OF MIA; THE R ENG FIRE WARNING CAME ON AND STAYED ON. AT THIS POINT; WE COMPLETED THE ENG FIRE/SEVERE CHKLIST. I FLEW THE ACFT. WE HAD ATC TO VECTOR US OUT SO WE COULD COMPLETE ALL CHKLISTS IN A NON-RUSHED MANNER. THE R ENG FIRE WARNING STAYED ON AFTER FIRING BOTH FIRE BOTTLES. AFTER LNDG; WE TOLD TWR TO HAVE FIRE ENGS CHK R ENG FOR FIRE; AS WE STILL HAD FIRE LIGHT WITH ENG SHUT DOWN AND BOTH BOTTLES FIRED. AT THE GATE; VISUAL INSPECTION CONFIRMED WHAT WE THOUGHT. THE FIRE WARNING WAS FALSE. HOWEVER; WITHOUT QUESTION; IT HAD TO BE TREATED AS REAL. I FEEL THE CAPT AND I HANDLED THIS EMER IN NOTHING LESS THAN PERFECT TEXTBOOK FORM. THIS SAYS A LOT OF OUR AIRLINE'S TRAINING AND PLTS.
