WDB AND LGT HAVE NMAC AS BOTH OF THEM FLY THE SAME VISUAL APCH TO SFO.

Narrative

WE HAD BEEN CLRED FMS QUIET BRIDGE VISUAL RWY 28R AT SFO. WE WERE APCHING THE 6.0 DME SFO AT SAN MATEO BRIDGE WHEN SFO APCH ASKED US IF WE SAW AN LGT HIGH OVER SAN FRANCISCO BAY. WE SAID WE HAD A VISUAL ON THE FLT. LGT WAS CLRED FOR A VISUAL TO RWY 28R AND WE WERE TOLD TO CHANGE RWY TO 28L. AT THIS TIME I PLANNED TO FLY OVER THE SAN MATEO BRIDGE BECAUSE OF THE NOISE SENSITIVE LAND AREA AND THEN MAKE A SLIGHT L TURN TO LINE UP WITH RWY 28L. I THOUGHT THAT THE LGT FLT WOULD SPACE HIS ACFT BEHIND AND TO THE R OF US. ABOUT THE TIME WE WERE XING THE BRIDGE; THE LGT FLT WAS CLOSING VERY FAST AND WAS IN A R BANK AND STILL HAD HIS GEAR UP. I HAD GEAR DOWN AND 20 DEGS FLAPS. I REALIZED I WAS NOW IN LGT'S AIRSPACE. AT THIS POINT I MADE A SHARP L DSNDING TURN HDG S ALONG THE BRIDGE TOWARD THE SHORE LINE. THE COPLT WHO COULD SEE LGT CLOSING VERY RAPIDLY SAID; 'LET'S GET OUT OF HERE!' WE ALSO HAD AN RA THREAT ON THE TCASII DISPLAY AND AURAL WARNING. I MADE A MISSED APCH. WE WENT AROUND AND LANDED ON 28R 10 MINS LATER. I THINK THE ONLY SOLUTION IS THAT SFO APCH SHOULD HAVE CLRED LGT FLT TO FOLLOW US. A MUCH BETTER SOLUTION WOULD BE TO FORGET ABOUT NOISE ABATEMENT AND SHOOT STRAIGHT-IN APCHS. SUPPLEMENTAL INFO FROM ACN 241449: ABEAM EACH OTHER OUR FINAL SEPARATION BECOMES NIL.
