SMA HAD NMAC WITH B747 IN CLASS B AIRSPACE. POSSIBLE LTSS SYS ERROR.

Narrative

I WAS FLYING AT 6500 FT CLRED INTO THE CLASS B AIRSPACE OVER HAYWARD ON MY WAY TO CLEAR LAKE; CA. I WAS ON 135.4. IT WAS APPROX AM15. I WAS FLYING VFR WITH THE CLASS B CLRNC. THE RADIO CTLR EXPLAINED THAT THERE WILL BE TFC AT MY 10 O'CLOCK. I LOOKED AND SAID 'NEGATIVE' ON THE TFC. I LOOKED AGAIN AND I NOW OBSERVED A 'LARGE' B747; AS I RECALL AT MY 10 O'CLOCK. I COULD SEE ALL 4 ENGS. IT WAS VERY CLOSE AT THE TIME. I REGISTERED MY CONCERN; AS I RECALL; OVER THE RADIO; THE CTLR CAME BACK AND EXPLAINED THAT HE WANTED MY PLANE TO 'CROSSOVER ABOVE AND BEHIND' THE LARGER AIRPLANE. I REALIZED THAT WE WERE GETTING TOO CLOSE FOR MY COMFORT. AT THAT TIME HE DIRECTED ME TO TURN TO A HDG OF 270 DEGS. I WAS FLYING 317 DEG HDG; HE WAS DIRECTING ME RIGHT AT THE B747. I TURNED TO THE HDG. THE B747 WAS NOW OUT OF MY SIGHT UNDER MY NOSE. WE WERE NOW CLOSING QUICKLY; THE B747 GOING 250 KTS AND CLBING LOOKING INTO THE SUN. HE NEVER HAD ME IN SIGHT FOR I NEVER HEARD THAT HE HAD THE TFC. I WAS GOING CLOSE TO 200 MPH. AT THIS RATE WE WOULD BE IN CLOSE PROX WITHIN 2-3 SEC. I DECIDED TO REFUSE TO FLY THE 270 DEG HDG. I CALLED ON THE RADIO AND TOLD CTLR I AM TURNING TO 180 DEG HDG TO AVOID THE TFC. AS I DID THAT I PUT MY NOSE DOWN TO KEEP MY EYE ON THE B747 AS I COMPLETED THE TURN AND WATCHING THE B747 CLB. IT PASSED BEHIND ME AT APPROX 400 FT! IT NEVER STOPPED AT 6000 FT; IT JUST KEPT ON GOING! I CAME BACK ONTO THE RADIO AND TOLD THE CTLR THAT I DID NOT APPRECIATE HIM VECTORING ME INTO THE PATH OF A VERY LARGE ACFT. HE THEN VECTORED ME OUT OF THE CLASS B AIRSPACE AND AT WHICH POINT I STARTED ON BACK TO A HDG OF 317 DEGS TO CLEAR LAKE. I THEN SPOKE WITH 120.9 THEN 127.8 ZOA. I NEVER RE-ENTERED THE CLASS B AIRSPACE FOR I WAS 11.5+ DME FROM THE OAKLAND VOR. I FEEL THAT I DID THE RIGHT THING IN DEVIATING FROM THE CTLR DIRECTION.
