Narrative:

We were on a descending vector to the ILS runway 28R sfo. A B767 was on a departure from sjc. We received a TCAS RA while in a descending turn to the left to line up for runway 28R sfo. I pitched the aircraft down to follow the TCAS guidance until we were clear of conflict. I would estimate we passed co-altitude less than 1/2 mi. The other aircraft queried the controller about the incident to which he responded 'you said you had visual contact. Check your remarks.' we did not query the controller.

Title: B747 ON APCH FOR RWY 28R AT SFO EXPERIENCED TCAS RA WITH TFC OFF SJC.

Narrative: WE WERE ON A DSNDING VECTOR TO THE ILS RWY 28R SFO. A B767 WAS ON A DEP FROM SJC. WE RECEIVED A TCAS RA WHILE IN A DSNDING TURN TO THE L TO LINE UP FOR RWY 28R SFO. I PITCHED THE ACFT DOWN TO FOLLOW THE TCAS GUIDANCE UNTIL WE WERE CLR OF CONFLICT. I WOULD ESTIMATE WE PASSED CO-ALT LESS THAN 1/2 MI. THE OTHER ACFT QUERIED THE CTLR ABOUT THE INCIDENT TO WHICH HE RESPONDED 'YOU SAID YOU HAD VISUAL CONTACT. CHK YOUR REMARKS.' WE DID NOT QUERY THE CTLR.
