CAPT OF AN ATR42 STOPPED DSNDING ON ARR AND STARTED CLBING IN RESPONSE TO A TCASII RA. HE THEN SIGHTED THE TARGET; A CL65; CLBING OUT AND STOPPED CLBING TO ASSURE SEPARATION.

Narrative

ACR X (FPO-MIA) ON NOV/MON/00. I WAS CAPT (AND THE PF) ON THE ATR42. WE WERE TALKING TO MIA APCH ON 124.85. THEY HAD JUST TURNED US TO A 270 DEG HDG AT 8000 FT. MIA INTL WAS LNDG E. TCASII ALERTED US TO 'TFC' AND AT OUR 10 O'CLOCK POS; I SAW AN ACR Y REGIONAL JET CLBING. THEY WERE TALKING TO MIA DEP ON A DIFFERENT FREQ. THIS SCENARIO IS NOT UNCOMMON IN MIAMI; BUT THE TFC DEPARTING MIAMI (USUALLY HEADING APPROX 300-330 DEGS) NORMALLY LEVELS OFF AT 7000 FT UNTIL THE 8000 FT TFC IS W OF THEIR POS. THE ACR Y 'RJ' CONTINUED CLBING. MY TCASII ALERTED ME WITH AN RA TO 'CLB; CLB.' IT BECAME OBVIOUS THAT ACR Y WAS NOT GOING TO LEVEL OFF AT 7000 FT AND I COULD SEE HIM VISUALLY CLBING IN FRONT OF MY ACFT AND THROUGH MY ALT. I DECIDED THAT OBEYING THE TCASII AND CLBING MY ACFT WOULD BE MORE DANGEROUS THAN TO MAINTAIN MY ALT (BECAUSE I WOULD LOSE SIGHT OF ACR Y). ATC NEVER CALLED THE TFC TO US; SO I INITIATED A CALL TO APCH TO LET THEM KNOW I HAD THE TFC IN SIGHT; BUT WAS GETTING AN RA. HE PAUSED; AND THEN ALERTED ME TO 'TFC' AT 2 O'CLOCK POS. AFTER LNDG IN MIAMI; MY COMPANY TOLD ME TO CALL APCH ON THE TELEPHONE. I DID THAT AND GAVE THE SUPVR MY SIDE OF THE STORY AND HE (IN A RATHER UNFRIENDLY TONE OF VOICE) SAID HE WAS LOOKING INTO IT AND WOULD GET IN TOUCH WITH ME IF HE NEEDED TO.
