PA28 PLT VIOLATED THE DC ADIZ.

Narrative

WE WERE DEPARTING CVG PEPPER ARPT; VA; ENRTE TO GAI. LEESBURG FSS ADVISED TO CONTACT POTOMAC APCH TO OPEN THE ADIZ FLT PLAN UPON REACHING CSN; JUST OUTSIDE THE WASHINGTON; DC; ADIZ. AT 3 MI S OF CSN; WHILE FLYING AT 1500 FT AGL; I CONTACTED PCT REQUESTING TO OPEN OUR ADIZ FLT PLAN TO GAITHERSBURG. THE CTLR INFORMED US SHE DID NOT HAVE OUR FLT PLAN; AND WE WERE NOT IN THE SYS. WE ATTEMPTED TO STAY CLR OF THE ADIZ; WHILE STILL FLYING A W; NW HDG AT 1500 FT AGL. WE WERE USING A GPS IN AN ATTEMPT TO MOVE TO A DIFFERENT PCT QUADRANT AND CTLR; YET STILL STAYING CLR; I BELIEVED; OF THE ADIZ. PCT PROVIDED A SQUAWK CODE. SHORTLY AFTER RECEIVING THE SQUAWK CODE; PCT REQUESTED WE HAVE A 'PEN AND PAPER READY.' I RESPONDED TO PCT AND ASKED THEY 'STAND BY.' I INFORMED THEM I WAS READY TO COPY. AT THAT TIME; I WAS TOLD TO COM A PHONE NUMBER. WE WERE CLRED TO GAITHERSBURG THROUGH THE CLASS B AIRSPACE AND CALL AFTER LNDG. THEN; AFTER LNDG AT MONTGOMERY COUNTY AIRPARK; I IMMEDIATELY CONTACTED THE NUMBER PROVIDED; AND GOT THE SAME CTLR; WHO ADVISED ME HE WAS THE SHIFT SUPVR. HE FURTHER INFORMED ME THAT; WHEN I CONTACTED HIM NEAR UPPERVILLE; VA; I WAS AT THAT TIME 4 MI INSIDE THE ADIZ. THE UPPERVILLE; VA; AREA IS LOCATED AT THE FAR NW CORNER OF THE WASHINGTON DC ADIZ. HE TOLD ME HE HAD TO FILE A 'PLT DEV' RPT; AND THAT FLT STANDARDS WOULD BE CONTACTING ME. WHEN I EXPLAINED THE CIRCUMSTANCES AND ASKED WHY I WAS NOT IN THE SYS; WHEN I BELIEVED MY WINDOW FOR OPENING A FLT PLAN WAS 1 HR BEFORE SCHEDULED DEP TIME; HE INFORMED ME THAT AN ADIZ WINDOW FOR OPENING A FLT PLAN IS 20 MIN BEFORE; UNTIL 2 HRS AFTER; SCHEDULED DEP TIME. AT THAT TIME; HE ASKED ME FOR MY NAME; ADDRESS; AND TELEPHONE NUMBER; WHICH I PROVIDED. I BELIEVE PROVIDING THE SAME WINDOW FOR OPENING AN ADIZ FLT PLAN (1 HR VICE 20 MINS) AS FOR A VFR FLT PLAN (1 HR BEFORE) WOULD HAVE PREVENTED THIS ALLEGED INFRACTION. WHILE WE WERE WELL OUTSIDE THE WASHINGTON; DC; ADIZ; S OF CASANOVA; WE ATTEMPTED TO CORRECTLY ACTIVATE OUR ADIZ FLT PLAN; WHICH PCT DID NOT HAVE. IF THE 1 HR OPENING FLT PLAN RULE HAD BEEN APPLICABLE; THIS ALLEGED INCIDENT PROBABLY WOULD NOT HAVE HAPPENED.
