SMA ENTERS CLASS B AIRSPACE IN MEXICO AND CALIFORNIA.

Narrative

I WAS FLYING FROM SAN FELIPE; MEXICO; TO SAN DIEGO; SDM FOR A CUSTOMS STOP BEFORE PROCEEDING TO VAN NUYS (DEST). I CONTACTED TIJUANA TWR ABOUT 25 MI SE AND ADVISED I WOULD LIKE TO OVERFLY AT 8500 ENRTE TO BROWN FIELD. TIJ TWR ACKNOWLEDGED ME AFTER A COUPLE OF CALLS; BUT ONLY INSTRUCTED ME TO MAINTAIN 8500 FT. AFTER A MIN OR 2 TWR HANDED ME OFF TO TIJ APCH CTL. BY THIS TIME; I WAS ABOUT 18 DME. APCH ASKED ME IF I SAW THE MEXICANA 727 BELOW ME AND I REPLIED I HAD VISUAL CONTACT. HE ASKED ME IF I HAD A DME AND I REPLIED I DID. HE THEN ASKED IF I KNEW HOW TO USE IT AND I REPLIED I DID. HE ASKED WHY I WAS USING XPONDER CODE. I ADVISED HIM I HAD CALLED SAN DIEGO RADIO EARLIER AND THEY GAVE ME THE CODE. (I'M NOT SURE ABOUT THE EXACT CODE) THE CTLR THEN GAVE ME A DIFFERENT XPONDER CODE AND ADVISED I WAS FLYING IN THE TCA. I SAID I KNEW THAT; BUT I HAD BEEN IN CONTACT WITH THE TIJ TWR. HE ASKED WHY I HAD NOT CALLED BARRIER. I SAID I CALLED AT 25 MI. HE SAID THE TCA WENT OUT TO 70 MI. I ASKED HIM SEVERAL TIMES IF HE WAS SAYING 70 MI. I ASKED HIM SEVERAL TIMES IF HE WAS SAYING 70 MI AND HE SAID YES. HE SPOKE GOOD ENGLISH; BUT WAS VERY EXCITED. I APOLOGIZED AND HE HANDED ME OFF TO SAN DIEGO APCH. BY THIS TIME I WAS IN THE SAN DIEGO CLASS B AND THEY ASKED FOR AN EXPLANATION. I EXPLAINED I WAS JUST HANDED OFF TO HIM AND HE SAID HE WOULD LET IT GO THIS TIME. I CALLED TIJ APCH BY TELEPHONE AFTER LNDG AT SDM. THE CTLR SAID THE 727 HAD TCASII AND THERE WAS NOT A NEAR MISS; BUT BOTH HE AND THE ACR PLT WERE UPSET WITH ME. I WAS USING THE COMMERCIAL LOW ALT LA H/L ENRTE CHART PLUS SAN DIEGO TCA AND APCH CHARTS. NONE SHOW A 70 MI RING; BUT THE LOW ALT CHART SHOWS A 25 MI RING. NO TIJ TCA CHART.
