Narrative:
On tipp-toe visual runway 28L in sfo, received TCASII RA approximately 900 ft AGL on final and went around. Had traffic in sight from approximately 20 mi out landing runway 28R (a B767). Received traffic alert approximately 1200 ft. Asked PF if still had traffic, which was behind and to the right -- reported yes. At 900 ft, received RA and traffic appeared left of centerline for runway 28R. Went around. All SOP's and FARS followed. Supplemental information from acn 532925: I had traffic in sight, so we continued the approach while configuring and slowing. Passing 1200 ft MSL on GS, TCASII gave a climb RA. The B767 appeared to be going through the runway 28R localizer course and was on a collision course, so I initiated a climb go around.

Title: AN A320 CREW, ON FINAL TO SFO, EXECUTED A GAR WHEN TFC FOR THE PARALLEL CAUSED A CLB RA FROM TCASII.
Narrative: ON TIPP-TOE VISUAL RWY 28L IN SFO, RECEIVED TCASII RA APPROX 900 FT AGL ON FINAL AND WENT AROUND. HAD TFC IN SIGHT FROM APPROX 20 MI OUT LNDG RWY 28R (A B767). RECEIVED TFC ALERT APPROX 1200 FT. ASKED PF IF STILL HAD TFC, WHICH WAS BEHIND AND TO THE R -- RPTED YES. AT 900 FT, RECEIVED RA AND TFC APPEARED L OF CTRLINE FOR RWY 28R. WENT AROUND. ALL SOP'S AND FARS FOLLOWED. SUPPLEMENTAL INFO FROM ACN 532925: I HAD TFC IN SIGHT, SO WE CONTINUED THE APCH WHILE CONFIGURING AND SLOWING. PASSING 1200 FT MSL ON GS, TCASII GAVE A CLB RA. THE B767 APPEARED TO BE GOING THROUGH THE RWY 28R LOC COURSE AND WAS ON A COLLISION COURSE, SO I INITIATED A CLB GAR.
