Narrative:

Visual conditions at night sfo with visual approachs simultaneously to runways 28L/right. We were assigned by approach control to fly heading 250 degrees to intercept the localizer runway 28L. A second aircraft was on a right base for vectors to the visual runway 28R. We were advised of the traffic on right base for runway 28R by approach control. We responded the traffic in sight and were then cleared the visual to runway 28L and maintain visual separation from the traffic. We continued the visual approach by tracking the localizer and GS intercept at approximately 4000 ft. We continued visual contact with the aircraft on right base and the TCASII annunciated a TA. I monitored the aircraft and commented that it didn't look as though the aircraft was to turn on final approach for runway 28R. The aircraft did continue its present heading (right base leg) and flew through both approach courses of runways 28R and 28L. Our TCASII annunciated an RA to climb and showed the target moving below (-03 ft, 300 ft) and behind our position. A breakdown in communications between approach control and the other aircraft as to their clearance for runway 28R. Simultaneous visual approachs at night sfo is not the safest operation.

Title: MULTIPLE RWY OP PARALLEL RWYS ACR X TCASII TA RA WITH ACR Y NON ADHERENCE TO ATC CLRNC VISUAL APCH TO PARALLEL RWY. PLTDEV.

Narrative: VISUAL CONDITIONS AT NIGHT SFO WITH VISUAL APCHS SIMULTANEOUSLY TO RWYS 28L/R. WE WERE ASSIGNED BY APCH CTL TO FLY HDG 250 DEGS TO INTERCEPT THE LOC RWY 28L. A SECOND ACFT WAS ON A R BASE FOR VECTORS TO THE VISUAL RWY 28R. WE WERE ADVISED OF THE TFC ON R BASE FOR RWY 28R BY APCH CTL. WE RESPONDED THE TFC IN SIGHT AND WERE THEN CLRED THE VISUAL TO RWY 28L AND MAINTAIN VISUAL SEPARATION FROM THE TFC. WE CONTINUED THE VISUAL APCH BY TRACKING THE LOC AND GS INTERCEPT AT APPROX 4000 FT. WE CONTINUED VISUAL CONTACT WITH THE ACFT ON R BASE AND THE TCASII ANNUNCIATED A TA. I MONITORED THE ACFT AND COMMENTED THAT IT DIDN'T LOOK AS THOUGH THE ACFT WAS TO TURN ON FINAL APCH FOR RWY 28R. THE ACFT DID CONTINUE ITS PRESENT HDG (R BASE LEG) AND FLEW THROUGH BOTH APCH COURSES OF RWYS 28R AND 28L. OUR TCASII ANNUNCIATED AN RA TO CLB AND SHOWED THE TARGET MOVING BELOW (-03 FT, 300 FT) AND BEHIND OUR POS. A BREAKDOWN IN COMS BTWN APCH CTL AND THE OTHER ACFT AS TO THEIR CLRNC FOR RWY 28R. SIMULTANEOUS VISUAL APCHS AT NIGHT SFO IS NOT THE SAFEST OP.
