Narrative

I WAS ON A VFR FLT FROM SMO THROUGH THE SPECIAL FLT RULES CORRIDOR OVER LAX TO THE OCEAN SIDE VOR AND RETURN TO CHK A RECENTLY REPAIRED REGULATOR WHEN AT APPROX XA00 PM; I BEGAN TO ENTER THE SPECIAL FLT RULES CORRIDOR OVER LAX IN A NW DIRECTION. I WAS AT 4500 FT MSL AND ATTEMPTING TO INTERCEPT THE 132 DEG RADIAL OF THE SANTA MONICA VOR. THE SUN WAS VERY LOW IN THE SKY AND THERE WAS A VERY HVY HAZE AND SCATTERED CLOUDS BELOW ME WITH TOPS AT APPROX 3500 FT. BECAUSE OF THE SUN AND HAZE FORWARD VISIBILITY WAS VERY POOR. AS THE NEEDLE ON MY VOR CTRED INDICATING THAT I WAS ON COURSE TO TRAVERSE THE SPECIAL FLT RULES CORRIDOR I COULD SEE DIRECTLY BELOW ME WHAT APPEARED TO ME TO BE THE COASTLINE. FROM THIS OBSERVATION I CONCLUDED THAT MY VOR INDICATION WAS FAULTY AND THAT I WAS ENTERING AN AREA OF CONFLICT WITH THE COMMERCIAL TFC DEPARTING LAX SO I TOOK A HEADING TO THE R TO POS MY ACFT WHERE I BELIEVED I SHOULD BE TO PASS OVER LAX. MY GND SPD WAS 140 KTS AND BEFORE I REALIZED THAT MY VOR INDICATOR WAS PROVIDING ME WITH CORRECT INFO AND THAT WHAT I BELIEVED TO BE THE SHORELINE WAS PROBABLY A FREEWAY I HAD STRAYED INTO THE LOS ANGELES CLASS B AIRSPACE. I IMMEDIATELY TURNED TO A HEADING TO RECAPTURE THE 132 DEG RADIAL OF THE SANTA MONICA VOR AND COMPLETED MY TRANSITION OF THE CORRIDOR. MY ALT VARIED DURING THIS TIME FROM 4000-4800 FT BECAUSE OF MY CONFUSION. I AM NOT CERTAIN I ENTERED THE CLASS B AIRSPACE BUT SUSPECT THAT I DID. IN RETROSPECT; I SHOULD HAVE BELIEVED MY INSTS RATHER THAN VISUAL CUES IN A LOW VISIBILITY SIT. BETTER STILL; I SHOULD HAVE FILED AN INST FLT PLAN. I AM ALSO CONTEMPLATING THE PURCHASE OF A GPS DEVICE WITH A MOVING MAP. HAD I HAD THE USE OF A MOVING MAP DISPLAY; MY POS IN RELATION TO THE CLASS B AIRSPACE WOULD HAVE BEEN MORE EASILY DETERMINED.
