ERRONEOUS PENETRATION OF CLASS B AIRSPACE.

Narrative

AFTER AN IFR TO VFR ON TOP DEP; OUT OF HHR ALT 3.0/HDG 180 DEGS ASSIGNED BY SOCAL APCH; I CANCELLED IFR AND CONTINUED ON THE ASSIGNED HDG OF 180 DEGS AND PROCEEDED TO CLB TO 5000 FT TO CROSS THE SLI 251 DEG RADIAL AT OR BELOW 5000 FT. AFTER XING THE SLI 251 DEG RADIAL; I BEGAN A R TURN ON THE SLI 251 DEG RADIAL. I PROCEEDED TO CLB TO AT OR ABOVE 12500 FT IN ORDER TO CLR THE LAX CLASS B. I HAD BEEN GIVEN A 1200 CODE AND A FREQ CHANGE AS SOON AS I HAD CANCELLED IFR. DURING THE CLB AFTER THE TURN ON THE SLI 251 DEG RAIDAL; I SAW TFC AT ABOUT 1 O'CLOCK POS AND CONVERGING. A L TURN WOULD NOT HAVE BEEN SUFFICIENT TO CLR TFC. I TURNED TO THE R TO PASS BEHIND THE TFC. AFTER CLRING TFC I STARTED TO TURN L BACK TO THE 251 DEG RADIAL WHEN I NOTICED I HAD CROSSED INTO CLASS B AIRSPACE. IMMEDIATELY; I TURNED FURTHER L TO A HDG OF 180 DEGS AFTER CLRING THE 251 DEG RADIAL; BY A LARGER MARGIN THE SECOND TIME; I CONTINUED CLB AND MY TURN UNTIL WELL CLR OF THE CLASS B AIRSPACE. WHEN I FINALLY GOT FLT FOLLOWING I WAS EXPECTING A REPRIMAND OR A PHONE NUMBER TO CALL BUT RECEIVED NONE. INSTEAD THE CTLR ASKED ME WHICH ARPT I HAD DEPARTED; WHICH; TO ME; SOUNDED UNUSUAL. IN MY FLUSTERED STATE I RPTED I HAD LEFT FULLERTON. WHEN I WENT TO CORRECT WHAT I HAD SAID; THE CTLR WAS BUSY WITH OTHER ACFT. I DECIDED IT WAS UNIMPORTANT. MAYBE NOT. IN RETROSPECT; I HAVE DECIDED TO ALWAYS REMAIN IFR IN COMPLEX AIRSPACE; ESPECIALLY THE LAX CLASS B DUE TO ITS COMPLEXITY. I ALSO REALIZE THAT VOR AZIMUTH BECOME LESS ACCURATE AT GREATER DISTANCES. DUE TO THAT ERROR I MAY HAVE ENTERED CLASS B IN THE CLB BEFORE THE TURN WAS INITIATED. VOR AZIMUTH AND DME FROM THE LAX VOR WAS INOP. I WAS RELYING ON THE 251 DEG RADIAL AND THE LAST ASSIGNED HDG FROM ATC TO CLR ME OF THE TCA/CLASS B. I SHOULD HAVE REMAINED IFR OR AT LEAST NOT LET ATC TERMINATE RADAR SVC.
