A319 FLT CREW RECEIVES TCAS RA DURING ILS 9L AT FLL AND EXECUTES GAR. PF DOES NOT USE TOGA DETENT; PNF DOES NOT CALL POSITIVE RATE AND GEAR REMAINS DOWN THROUGHOUT THE GAR.

Narrative

ARRIVING ON THE FUSEL STAR TO RWY 9L FLL PROVIDED NO COMPLICATIONS. WE WERE INSTRUCTED TO INTERCEPT THE LOC AND CLRED FOR THE ILS RWY 9L FLL APCH BY THE MIA APCH CTLR. WE THEN SWITCHED OVER TO THE FLL TWR AND INFORMED THEM THAT WE WERE JUST OUTSIDE OF NOVAE INBOUND ON THE ILS RWY 9L FLL APCH. THE ACFT WAS FULLY CONFIGURED WITHIN 1-2 MI OF NOVAE AND COMPLETING THE LNDG CHKLIST. NO STABILIZED APCH CRITERIA WERE COMPROMISED. THE TWR ISSUED US A LNDG CLRNC FOR FLL RWY 9L. AT APPROX 1000 FT; WE RECEIVED AN RA MESSAGE FROM THE TCAS SYS INFORMING US OF TFC -200 FT AND 1-2 MI AHEAD. THE TWR DID NOT PROVIDE ANY AWARENESS THAT THERE WOULD BE A HELI BELOW THE GS DURING THE APCH AND LNDG. AS APPROPRIATE; THE CAPT EXECUTED A GAR AND WE BEGAN TO CLB TO 4000 FT. THE FLL TWR CTLR WAS CONFUSED AS TO WHY WE WERE GOING AROUND AND QUERIED US AS TO OUR ACTIONS. SPD BEGAN RISING RAPIDLY AND WE RETRACTED FLAPS TO 1 DEG ON SCHEDULE. THE CTLR STATED THAT WE WERE STILL CLRED TO LAND AFTER WE TOLD HIM THAT WE HAD AN RA -- THE CTLR DID NOT SEEM TO CARE ABOUT THE SITUATION. WE TOLD HIM THAT WE WERE GOING AROUND STILL BECAUSE WE WERE NOT IN ANY POS TO LAND. HE ASSIGNED A HDG AND ALT AND INSTRUCTED US TO CONTACT THE APCH CTLR AGAIN. DURING THE GAR EVENT; THE PF DID NOT ADVANCE THE THRUST LEVERS TO THE TOGA DETENT; AND THE FLT PLAN DID NOT SEQUENCE; IT DROPPED OUT COMPLETELY WHEN THE COMPUTER SENSED THAT WE 'PASSED' THE ARPT. THE ENTIRE SITUATION CAUGHT ME OFF GUARD (NO TCAS TA; JUST RA) AND I FAILED TO MAKE THE APPROPRIATE 'POSITIVE RATE' CALL-OUT TO THE PF TO PROMPT GEAR RETRACTION. I WAS MORE CAUGHT UP WITH THE CTLR INSTRUCTIONS AND THEN REPROGRAMMING THE BOX AND RETRACTING THE FLAPS. ON THE SECOND APCH; WE WERE FULLY CONFIGURED AGAIN JUST INSIDE NOVAE; ON A STABILIZED APCH. WE RECEIVED A TCAS TA OF ANOTHER HELI ABOVE THE GS +400 FROM OUR POS. AGAIN; TWR DID NOT PROVIDE ANY INFO ABOUT THESE HELIS DURING OUR APCH TO LNDG (BUT LATER STATED THAT HE KNEW THEY WERE THERE AND WOULD POSE NO CONFLICT). THE SECOND APCH CONTINUED TO A NORMAL LNDG WITHOUT ANY FURTHER COMPLICATIONS. AT NO TIME DID I OR MY CAPT HAVE VISUAL CONTACT WITH ANY OF THE HELIS IN THE AREA. IMPROPER ATC COM TO THE FLT CREW ABOUT ACFT IN THE VICINITY OF THE GS. IMPROPER PRIORITY OF DUTIES ON MY PART (THE PLT MONITORING) TO FIRST AVIATE; NAV; THEN COM LEFT THE GEAR DOWN DURING OUR CLB AND SUBSEQUENT APCH. IMPROPER PROC OF THE PF TO EXECUTE A GAR SOLELY IN THE CLB DETENT. IMPROVED COM FROM FLL TWR CTLR. ADHERENCE TO SOP'S ON A GAR BY THE FLT CREW; HOWEVER; AT NO TIME DURING THE GAR (AFTER THE RA) WAS THE SAFETY OF THE ACFT OR THE PAX AND FLT CREW COMPROMISED.
