IFR flight from bar harbor, me, to nantucket. Filed and cleared from bos VOR direct martha's vineyard direct nantucket. VFR WX. Estimated 25-30 mi south of boston, new clearance: direct hyannis V141 nantucket. Requested routing that would keep me closer to land (single engine). Departure unable. Requested IFR cancellation and traffic advisories. Departure provided advisory services. I assumed I was clear of the TCA on IFR cancellation or departure would have advised me otherwise. (No DME on board.) is this correct? In the event I was still in the TCA, does acceptance of cancellation and provision of VFR advisories constitute permission to continue through the TCA? If I was outside the TCA on cancellation, as I believe to be the case, or the answer to either question is 'yes,' there should be no violation of TCA. Otherwise there may have been a violation. I've asked 2 FSS stations the answers to these questions and they didn't know. Callback conversation with reporter revealed the following: reporter advised in callback that both the pilot and the controller have a responsibility to insure each understands what is expected. In other words, if the pilot cancels an IFR in the TCA, the controller should issue instructions if he wants him to exit the TCA, descend or heading change, or the pilot should request clearance to proceed through the TCA or exit. Since he was IFR at the time of the cancellation he is legally in the TCA and because he could not accept the routing change and cancels, you can't say he is now in violation.

Title: REFUSED REROUTING DUE FLT OVERWATER IN SINGLE ENGINE ACFT, CANCELLED IFR.
Narrative: IFR FLT FROM BAR HARBOR, ME, TO NANTUCKET. FILED AND CLRED FROM BOS VOR DIRECT MARTHA'S VINEYARD DIRECT NANTUCKET. VFR WX. ESTIMATED 25-30 MI S OF BOSTON, NEW CLRNC: DIRECT HYANNIS V141 NANTUCKET. REQUESTED ROUTING THAT WOULD KEEP ME CLOSER TO LAND (SINGLE ENG). DEP UNABLE. REQUESTED IFR CANCELLATION AND TFC ADVISORIES. DEP PROVIDED ADVISORY SVCS. I ASSUMED I WAS CLR OF THE TCA ON IFR CANCELLATION OR DEP WOULD HAVE ADVISED ME OTHERWISE. (NO DME ON BOARD.) IS THIS CORRECT? IN THE EVENT I WAS STILL IN THE TCA, DOES ACCEPTANCE OF CANCELLATION AND PROVISION OF VFR ADVISORIES CONSTITUTE PERMISSION TO CONTINUE THROUGH THE TCA? IF I WAS OUTSIDE THE TCA ON CANCELLATION, AS I BELIEVE TO BE THE CASE, OR THE ANSWER TO EITHER QUESTION IS 'YES,' THERE SHOULD BE NO VIOLATION OF TCA. OTHERWISE THERE MAY HAVE BEEN A VIOLATION. I'VE ASKED 2 FSS STATIONS THE ANSWERS TO THESE QUESTIONS AND THEY DIDN'T KNOW. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: RPTR ADVISED IN CALLBACK THAT BOTH THE PLT AND THE CTLR HAVE A RESPONSIBILITY TO INSURE EACH UNDERSTANDS WHAT IS EXPECTED. IN OTHER WORDS, IF THE PLT CANCELS AN IFR IN THE TCA, THE CTLR SHOULD ISSUE INSTRUCTIONS IF HE WANTS HIM TO EXIT THE TCA, DSND OR HDG CHANGE, OR THE PLT SHOULD REQUEST CLRNC TO PROCEED THROUGH THE TCA OR EXIT. SINCE HE WAS IFR AT THE TIME OF THE CANCELLATION HE IS LEGALLY IN THE TCA AND BECAUSE HE COULD NOT ACCEPT THE ROUTING CHANGE AND CANCELS, YOU CAN'T SAY HE IS NOW IN VIOLATION.
