Narrative

ON OR ABOUT XA30 ON 9/THU/01; I CALLED THE FLT SERVICE STATION AT XXX TO INQUIRE INTO WHEN I COULD DEPART YYY ARPT ON A VFR FLT. THEY SAID I COULD DEPART AT XD00 ON THE SAME DAY. BASED ON THIS INFO I WENT TO THE AIRPORT; PREFLTED THE ACFT AND CONTACTED THE ARPT MANAGER TO SEE IF HE HAD BEEN APPRAISED IF THE RELEASE FOR GENERAL AVIATION ACFT TO FLY. HE SAID HE WAS SO INFORMED AND READ TO ME FROM A DOCUMENT HE HAD STATING THE FLTS COULD BEGIN AT XD00. I LAUNCHED AT XD00 AND FLEW TO ZZZ AND WHEN I CALLED UNICOM FOR INFO; I WAS ADVISED THAT THE ARPT WAS NOT OPERATIONAL; BUT I COULD LAND AND COULD NOT TAKE OFF. OBVIOUSLY THERE HAD BEEN A CHANGE IN AIRSPACE USE AFTER I TALKED TO THE ARPT MANAGER AT THE DEPARTING ARPT. AFTER LNDG AT ZZZ; I CALLED APCH CTL ON THE TELEPHONE TO RPT MY LNDG AND I SPOKE TO A SUPVR. I EXPLAINED THE SIT TO HIM AND HE SAID HE HAD NO PROB WITH WHAT I HAD DONE UNDER THE CIRCUMSTANCES EXISTING AT THE TIME. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR ADVISED THAT THE FLT WAS ABOUT 1 HR 30 MIN IN LENGTH. HE ADVISED THAT HE WAS SURPRISED TO LEARN ON ARR TO ZZZ THAT HE WAS IN VIOLATION TO THE REINSTITUTED RESTR. BECAUSE HE HEARD ATC ISSUE CTL INSTRUCTIONS TO ACFT; HE WAS NOT ALERTED TO ANY POSSIBLE AIRSPACE CONFIGN CHANGE.
