JYO FBO NOTIFIES PA28 PLT AFTER DEPING TFC PATTERN TO CALL FAA SUPVR AT PCT.

Narrative

THE EVENT WAS I SQUAWKED 1200 IN THE NEWLY FORMED DC ADIZ AND FAILED TO CONTACT THE CTLING AGENCY; PCT APCH; BEFORE MY DEP. I ARRIVED AT THE ARPT TO GO ON A PLEASURE FLT TO PRACTICE LNDGS AND A BRIEF SIGHT-SEEING FLT IN THE LOCAL AREA. I HAD NOT FLOWN IN THE DC AREA FOR OVER TWO MONTHS. I HAVE; PREVIOUSLY OVER THE PAST TWO YEARS; LOGGED APPROX 100 HRS FROM JYO; SO I ASSUMED I WAS FAMILIAR WITH THE LOCAL PROCS. I COMPLETED A TRIP AROUND THE PATTERN AND DEPARTED TO THE N. JUST AFTER I LEFT THE PATTERN; I WAS CALLED BY THE JYO UNICOM AND WAS TOLD I NEEDED TO CONTACT PCT CLRNC ON 188.55. I WAS NOTIFIED THAT I HAD SQUAWKED 1200 IN AN ADIZ (WHICH I WAS UNAWARE THE ADIZ EXISTED). THEY GAVE ME PERMISSION TO RE-PENETRATE THE ADIZ; REMAIN CLR OF DULLES INT'L CLASS B; AND RETURN TO JYO FOR A FULL STOP. I WAS ASSIGNED A DISCRETE CODE AND TOLD I NEEDED TO CALL APCH VIA TELEPHONE ON THE GND. I ALSO RECEIVED A CALL FROM THE FAA A FEW DAYS LATER AND I'M EXPECTING A LETTER IN THE MAIL DEALING WITH THE EVENT. MY ASSESSMENT IS MY FAILURE TO OBTAIN A WX BRIEFING; THIS WAS BECAUSE I CHKED METAR AND TAF'S ONLINE AND CONCLUDED IT WAS A PERFECT VMC DAY. THE FLT SCHOOL FBO'S FAILURE TO NOTIFY ME OF THE RECENT ADDITION OF THE ADIZ. THE PEOPLE WHO DISPATCHED THE PLANE TO ME KNEW ME ON A PERSONAL BASIS AND WERE AWARE OF MY ABSENCE FROM THE AREA; YET FAILED TO NOTIFY ME OF THE VERY IMPORTANT AIRSPACE CHANGES.
