Narrative:

I was the CFI on a primary student training flight. The WX forecast and actual WX reports for our practice area indicated scattered clouds and greater than 10 mi visibility. We departed kanp on an ADIZ flight plan to the east. A few clouds at 12000 ft MSL were becoming more scattered, so we climbed above the clouds to 3500 ft and could see that the WX to the east was not scattered as forecast. The controller was so busy that I wanted to find an area to work in outside the ADIZ, even though the WX inside the ADIZ was better. We checked the AWOS at W29 which reported visibility greater than 10 mi and 12000 sct. I planned to work to the east of W29. At the ADIZ boundary, we informed ATC we were clear and changed to a 1200 code and 121.5. We turned northeast, away from the ADIZ, and remained clear by ground references. As the clouds below became thicker (they were becoming broken), we remained clear using the esn radio beacon and ground references. We worked in the area for approximately 30 mins. The WX below was now almost an undercast and we moved to south, as the WX below was clear in that area. While en route, the kesn CTAF radio operator advised that ATC had called and wanted us to contact them when on the ground. After contacting and receiving a squawk from ATC, we reentered the ADIZ and returned to kanp. We called ATC and they informed me that we had entered the ADIZ after our initially leaving it, while doing our airwork. If there was an inadvertent blunder into the ADIZ, it would be attributed to the WX below changing from scattered to broken, combined with clearing for traffic and instructing a basic student with heading, altitude, and airspeed control of a basic student pilot.

Title: A PA-28 CFI, FLYING MANEUVERS IN CLOSE PROX TO THE ZDC ADIZ, VIOLATED THE TFR.

Narrative: I WAS THE CFI ON A PRIMARY STUDENT TRAINING FLT. THE WX FORECAST AND ACTUAL WX RPTS FOR OUR PRACTICE AREA INDICATED SCATTERED CLOUDS AND GREATER THAN 10 MI VISIBILITY. WE DEPARTED KANP ON AN ADIZ FLT PLAN TO THE E. A FEW CLOUDS AT 12000 FT MSL WERE BECOMING MORE SCATTERED, SO WE CLBED ABOVE THE CLOUDS TO 3500 FT AND COULD SEE THAT THE WX TO THE E WAS NOT SCATTERED AS FORECAST. THE CTLR WAS SO BUSY THAT I WANTED TO FIND AN AREA TO WORK IN OUTSIDE THE ADIZ, EVEN THOUGH THE WX INSIDE THE ADIZ WAS BETTER. WE CHKED THE AWOS AT W29 WHICH REPORTED VISIBILITY GREATER THAN 10 MI AND 12000 SCT. I PLANNED TO WORK TO THE E OF W29. AT THE ADIZ BOUNDARY, WE INFORMED ATC WE WERE CLR AND CHANGED TO A 1200 CODE AND 121.5. WE TURNED NE, AWAY FROM THE ADIZ, AND REMAINED CLR BY GND REFERENCES. AS THE CLOUDS BELOW BECAME THICKER (THEY WERE BECOMING BROKEN), WE REMAINED CLR USING THE ESN RADIO BEACON AND GND REFERENCES. WE WORKED IN THE AREA FOR APPROX 30 MINS. THE WX BELOW WAS NOW ALMOST AN UNDERCAST AND WE MOVED TO S, AS THE WX BELOW WAS CLR IN THAT AREA. WHILE ENRTE, THE KESN CTAF RADIO OPERATOR ADVISED THAT ATC HAD CALLED AND WANTED US TO CONTACT THEM WHEN ON THE GND. AFTER CONTACTING AND RECEIVING A SQUAWK FROM ATC, WE REENTERED THE ADIZ AND RETURNED TO KANP. WE CALLED ATC AND THEY INFORMED ME THAT WE HAD ENTERED THE ADIZ AFTER OUR INITIALLY LEAVING IT, WHILE DOING OUR AIRWORK. IF THERE WAS AN INADVERTENT BLUNDER INTO THE ADIZ, IT WOULD BE ATTRIBUTED TO THE WX BELOW CHANGING FROM SCATTERED TO BROKEN, COMBINED WITH CLRING FOR TFC AND INSTRUCTING A BASIC STUDENT WITH HDG, ALT, AND AIRSPD CTL OF A BASIC STUDENT PLT.
