Narrative:

Rarely do I fly VFR. When I do, even with IFR to VFR on top, I am able to initiate a normal turn for a downwind departure/climb out to the northeast of sna. On this day I was vectored maybe 15 NM to southwest for climb (IFR to VFR) before getting clearance to turn nebound to leave los angeles basin. I was using an angus to identify the corner of the outer radial of the class B airspace outside which I could proceed with my VFR climb. On this day, flight following was terminated by coast approach (unusual for this to be declined). I was much higher than normal due to my swbound climb vector. I was using my current lax sectional, my lax terminal chart was out of reach. I failed to remember or see on the sectional or angus that the lax class B airspace now projects over my flight path at 10000 ft/7000 ft. I was focused on missing the 10000 ft/6000 ft corner by flying to the east. Before canceling flight following the controller told me to stay outside class B airspace. I said I would stay just to the east of the boundary. In fact, I might have climbed up through the 7000 ft floor of the redesigned airspace, the relevant segment of which I forgot, and did not see was there.

Title: A PVT PLT CLBS UP THROUGH THE BASE OF THE LAX TCA CLASS B ON AN IFR CLB TO VFR ON TOP DEP FROM SNA.

Narrative: RARELY DO I FLY VFR. WHEN I DO, EVEN WITH IFR TO VFR ON TOP, I AM ABLE TO INITIATE A NORMAL TURN FOR A DOWNWIND DEP/CLBOUT TO THE NE OF SNA. ON THIS DAY I WAS VECTORED MAYBE 15 NM TO SW FOR CLB (IFR TO VFR) BEFORE GETTING CLRNC TO TURN NEBOUND TO LEAVE LOS ANGELES BASIN. I WAS USING AN ANGUS TO IDENT THE CORNER OF THE OUTER RADIAL OF THE CLASS B AIRSPACE OUTSIDE WHICH I COULD PROCEED WITH MY VFR CLB. ON THIS DAY, FLT FOLLOWING WAS TERMINATED BY COAST APCH (UNUSUAL FOR THIS TO BE DECLINED). I WAS MUCH HIGHER THAN NORMAL DUE TO MY SWBOUND CLB VECTOR. I WAS USING MY CURRENT LAX SECTIONAL, MY LAX TERMINAL CHART WAS OUT OF REACH. I FAILED TO REMEMBER OR SEE ON THE SECTIONAL OR ANGUS THAT THE LAX CLASS B AIRSPACE NOW PROJECTS OVER MY FLT PATH AT 10000 FT/7000 FT. I WAS FOCUSED ON MISSING THE 10000 FT/6000 FT CORNER BY FLYING TO THE E. BEFORE CANCELING FLT FOLLOWING THE CTLR TOLD ME TO STAY OUTSIDE CLASS B AIRSPACE. I SAID I WOULD STAY JUST TO THE E OF THE BOUNDARY. IN FACT, I MIGHT HAVE CLBED UP THROUGH THE 7000 FT FLOOR OF THE REDESIGNED AIRSPACE, THE RELEVANT SEGMENT OF WHICH I FORGOT, AND DID NOT SEE WAS THERE.
