Narrative:

On jul/sat/01 on the way back from nantucket to leesburg, va, a potential class B airspace violation occurred in conjunction with a cancelled IFR clearance. I had been cleared in the be-58 that I was flying via direct kroll intersection to jyo, descend from 6000 ft to 4000 ft, did I see the descending airline guy that was going down to 5000 ft, 12 O'clock position and 5 mi, sbound? Yes I did. After passing kroll and sbound to jyo, I said I could cancel IFR and go direct to the field. At this point, dulles approach normally gives you a cancellation and clearance into the class B airspace. At this point, I was about 18 mi north of aml at 3500 ft and definitely in the class B airspace. However, dulles approach instead said cancellation received and remain clear of the class B airspace. I quickly descended to remain clear but think that in my desire to let the airline guy about me and 5 mi ahead be able to descend sooner, I may have inadvertently violated the airspace. I quickly descended to 2400 ft about 16 NM north of aml and was down to 1400 ft 13 NM north of aml.

Title: BE58 PLT ENRTE TO JYO CANCELLED IFR N OF THE ARPT STILL IN CLASS B AIRSPACE.

Narrative: ON JUL/SAT/01 ON THE WAY BACK FROM NANTUCKET TO LEESBURG, VA, A POTENTIAL CLASS B AIRSPACE VIOLATION OCCURRED IN CONJUNCTION WITH A CANCELLED IFR CLRNC. I HAD BEEN CLRED IN THE BE-58 THAT I WAS FLYING VIA DIRECT KROLL INTXN TO JYO, DSND FROM 6000 FT TO 4000 FT, DID I SEE THE DSNDING AIRLINE GUY THAT WAS GOING DOWN TO 5000 FT, 12 O'CLOCK POS AND 5 MI, SBOUND? YES I DID. AFTER PASSING KROLL AND SBOUND TO JYO, I SAID I COULD CANCEL IFR AND GO DIRECT TO THE FIELD. AT THIS POINT, DULLES APCH NORMALLY GIVES YOU A CANCELLATION AND CLRNC INTO THE CLASS B AIRSPACE. AT THIS POINT, I WAS ABOUT 18 MI N OF AML AT 3500 FT AND DEFINITELY IN THE CLASS B AIRSPACE. HOWEVER, DULLES APCH INSTEAD SAID CANCELLATION RECEIVED AND REMAIN CLR OF THE CLASS B AIRSPACE. I QUICKLY DSNDED TO REMAIN CLR BUT THINK THAT IN MY DESIRE TO LET THE AIRLINE GUY ABOUT ME AND 5 MI AHEAD BE ABLE TO DSND SOONER, I MAY HAVE INADVERTENTLY VIOLATED THE AIRSPACE. I QUICKLY DSNDED TO 2400 FT ABOUT 16 NM N OF AML AND WAS DOWN TO 1400 FT 13 NM N OF AML.
