AN M20T PENETRATED CLASS B AIRSPACE WITHOUT CLRNC.

Narrative

I WAS RECEIVING FLT FOLLOWING FROM SOCAL APCH WHILE CLBING FROM SNA TOWARD VGT. THE CTLR ASKED MY REQUESTED ALT; TO WHICH I REPLIED I WOULD STAY AT 9500 FT TO AVOID CONFLICTS WITH LAX DSCNT OVER ONTARIO. HE STATED I COULD ADVISE THE NEXT SECTOR AND HANDED ME OFF; WHO ASKED AGAIN; AND WHEN I STATED 11500 FT; SAID 'CLB TO 11500 APPROVED.' AS I WAS CLBING THROUGH 9800 FT; I REALIZED I MIGHT BE IN CLASS B AIRSPACE AND INITIATED AN IMMEDIATE AND RAPID DSCNT TO 9000 FT. AT THAT POINT; I CHKED MY GPS AND CHARTS AND CONFIRMED I HAD ENTERED CLASS B WITHOUT A CLRNC. I HAVE DONE THIS MANY TIMES AND KNOW THAT I SHOULD NOT CLB ABOVE 9500 FT UNTIL AFTER LEAVING THE LAX CORRIDOR. USUALLY HOWEVER; MY RTE DOES NOT TAKE ME UNDER CLASS B AIRSPACE. ON THIS DAY; I HAD RECEIVED AN IFR CLRNC TO ON TOP; WHICH TOOK ME FURTHER N THAN USUAL; SO THAT WHEN I NAVED DIRECT TO VGT THE RTE WENT THROUGH CLASS B. I DID NOT THINK TO CHK MY POS 'VIZ' THE CLASS B UNTIL TOO LATE. THIS INCIDENT TAUGHT ME TO ALWAYS KNOW MY POS; ESPECIALLY RELATIVE TO RESTR OR CTLED AIRSPACE AND TO THINK PROACTIVELY WHEN CHANGING ALT OR HDGS. I MUST ALSO NOT INFER THAT A VFR CLB APPROVAL SIGNIFIES CLASS B CLRNC -- CLRLY IT DOES NOT!
