ERRONEOUS PENETRATION OF AIRSPACE.

Narrative

ON THE EVENING OF DEC/XX/94; I WAS ENRTE FROM CRG TO ORL ON THE FINAL LEG OF MY BANK CARGO RUN. DURING MY DSCNT FROM A CRUISING ALT OF 5500 FT; I NOTICED THE SCATTERED LAYER OF CLOUDS ALONG MY RTE HAD BEGUN TO GET MORE BROKEN OFF TO THE E OF THE AIRWAY. I DODGED SOME BUILDUPS DURING MY DSCNT TO 1500 FT AND WHEN I LEVELED OFF; I NOTICED THE INTERSTATE HWY WAS SLIGHTLY OFF TO MY R INSTEAD OF BEING TO THE L AS USUAL. THE VOR RECEIVER SHOWED ME ON THE AIRWAY; BUT ACCORDING TO THE CHART; I WAS SLIGHTLY INSIDE SFB CLASS D AIRSPACE. I CORRECTED COURSE TO THE R AND CONTINUED S TO ORL. AS I CALLED THE TWR AT ORL; A SBOUND HELI ASKED ORL TWR TO RELAY A MESSAGE FROM SFB TWR FOR THE SBOUND TFC (ME) TO CALL SFB TWR. I CALLED SFB TWR WHEN I GOT TO THE COMPANY OFFICE; AND THE DUTY CTLR AND I HAD A FRIENDLY CHAT. HE WAS CONCERNED BECAUSE THE CLASS D AIRSPACE HAD GONE IFR JUST BEFORE MY INCURSION; AND THERE HAD BEEN ACFT ON THE ILS COURSE; WHICH I HAD CROSSED SBOUND. HE SUGGESTED THAT I CALL SFB TWR FOR TRANSITION IF THERE IS EVER ANY DOUBT ABOUT MY POS IN THE FUTURE; AND INDICATED THAT HE MERELY INTENDED TO CAUTION ME IN THIS MATTER. HOPEFULLY; THIS IS THE CASE. IN THE FUTURE; IF I LOSE SIGHT OF MY REGULAR LANDMARKS ALONG THIS SECTION OF MY RTE; I WILL GIVE A WIDER BERTH TO THE SFB CLASS D BOUNDARY; WHICH RUNS RIGHT UP TO THE AIRWAY IN THIS AREA. I WILL ALSO OBTAIN RADAR SVC; EVEN THOUGH I REMAIN CLR OF ORLANDO CLASS B WHEN I LAND AT ORL VFR.
