PLT OF A BEECH BE24 SIERRA INADVERTENTLY PENETRATED THE LAX CLASS B AIRSPACE DURING A VFR ON TOP XCOUNTRY FLT.

Narrative

ON OCT/XA/99 IN PREPARATION FOR A FLT FROM MYF TO LPC; I OBTAINED A BRIEFING AND WAS INFORMED THAT THE LAX VOR WAS OTS. I DEPARTED MYF AT ABOUT XA00 IFR TO VFR ON TOP AND CLBED TO 4500 FT MSL ARRIVING IN LPC XF30 HRS AFTER DEP. THROUGHOUT THE CRUISE PORTION OF FLT; I MAINTAINED THE 4500 FT ALT. AFTER CANCELING IFR I REQUESTED VFR ADVISORIES AND REMAINED IN CONTACT WITH ATC UNTIL REACHING THE GVO VOR WHERE I CANCELED FLT FOLLOWING. THE LOS ANGELES AREA WAS COVERED WITH A SOLID LAYER OF CLOUDS WITH TOPS ABOUT 2000 FT AND NO SURFACE FEATURES WERE VISIBLE IN THE LOS ANGELES BASIN. AT 4500 FT FORWARD VISIBILITY WAS UNRESTR. I MAKE THE MYF TO LPC TRIP FREQUENTLY AND PLANNED TO FOLLOW V25 TO LAX AND THEN DEPENDING ON ATC INSTRUCTIONS FOLLOW THE LAX SHORELINE RTE OR IF UNAVAILABLE THE LAX SPECIAL FLT RULES RTE. MY USUAL PROC IS TO USE THE LAX VOR TO IDENT V25 AS I APCH THE LOS ANGELES HARBOR BUT SINCE THE LAX VOR WAS DOWN; I CONTINUED TO NAV PAST SXC 022 DEG RADIAL USING THE MZB VOR. CLRLY USE OF SLI AND SXC OR SMO WOULD HAVE BEEN A BETTER CHOICE. I REQUESTED THE LAX SHORELINE RTE FROM THE 3RD OR PERHAPS 4TH SOCAL CTLR I CHKED IN WITH AFTER LEAVING SAN DIEGO. AS I APCHED LAX; I WAS INSTRUCTED BY ATC TO 'TURN W;' AND I TURNED TO A HDG OF 270 DEGS. A SHORT TIME LATER THE SAME CTLR GAVE ME A FREQ CHANGE AND ADVISED THAT HE HAD CALLED ME SEVERAL TIMES. I HAD RESPONDED TO ALL CALLS I HEARD AND HAD NOT CHANGED THE SETTINGS OF EITHER 'COM' RADIOS. I HAVE HAD NO KNOWN 'COM' RADIO PROBS BEFORE OR AFTER THIS EVENT. I DID CHANGE A 'NAV' TO SLI AFTER THE INSTRUCTION TO TURN W. THE NEW CTLRS INSTRUCTED ME TO 'TURN N' AND I TURNED TO A HDG OF 360 DEGS. HE ALSO ASKED THAT I CALL ATC ON THE PHONE REGARDING A POSSIBLE CLASS B AIRSPACE VIOLATION. UPON REACHING LOMPOC; I CALLED ATC AND TALKED TO ONE OF THE CTLRS INVOLVED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR WAS GIVEN COUNSELING BY THE FAA AFTER THEIR INVESTIGATION OF THIS INCIDENT.
