Narrative:

On a pleasure flight between dover, de, and winchester, va, I departed chandelle airport headed for winchester. This was a VFR flight that necessitated navigating near and potentially through class B airspace in the baltimore area. I called FSS to find out about tfrs in the area and any other restrs or enhancements to the airspace. About 10 mi from the class B airspace as depicted on my sectional chart, I radioed baltimore approach. After calling them a number of times, I did not hear a reply to my call. The air waves were extremely busy with much static and various other calls being stepped on. I remained clear of the class B airspace going just underneath the ring and generally in the direction I needed to go. However, due to the congestion of airspace in this area, I pursued a class B transition. Finally I began to get a little nervous. It was then that I realized that the sectional chart which I was using for navigation was out of date. I had inadvertently grabbed 1 of 2 sectionals for washington. I always keep older sectionals around to mark up with pen and pencil, keeping the newer ones clean and more readable. The one I mistakenly selected was indeed out of date (by 8 months -- it was the preceding chart that had been issued). In the confusion of making radio calls unanswered, navigating complex VFR airspace, staying clear of class B airspace, etc, I was also using an out-of-date chart. I then asked my friend (who was asleep) to help me out and look for the current chart which I knew was in the plane. He finally found it after several mins. Just about that time I heard a radio call from approach looking for an aircraft squawking 1200. I assumed that the call was meant for me -- the return radio call from approach. My friend again helped out and answered the call and obtained a squawk code for me. I studied the more up-to-date chart and was shocked to find that the dc ADIZ included the area in which I was flying! -- Not so with the previous sectional chart. I had entered the ADIZ without obtaining a squawk code and had proceeded about 5 mi into it before getting a code. Shortly thereafter, the voice on the radio asked me to call a phone number once we landed. Again my friend made the call to explain what had happened, as he is more experienced than I when it comes to this type of matter and I, realizing that I had made a flight into ADIZ airspace, though just a short while, was very serious indeed. My friend called the number, but rather than listen to his explanation they simply asked for and were given his name and pilot certificate number. Actually he tried to explain that I was PIC but they apparently were so busy and rushed themselves that he could not get a word in edgewise and so it was left at that. They probably assumed that he was PIC. However, I had plted the plane into an ADIZ by virtue of having referenced the wrong chart and did not have the situation corrected until I received a squawk code about 5-10 mi into the ADIZ. I never did get a class B transition. I remained on the code until exiting the ADIZ. I know that any flight into such an airspace is very serious. However, I can see that without up-to-date information of all kinds that such an event is possible.

Title: 2 RATED PLT ABOARD A C170 ENTER THE DC ADIZ WITHOUT AUTH. PLT WERE USING AN OUTDATED CHART THAT DID NOT DISPLAY THE ADIZ.

Narrative: ON A PLEASURE FLT BTWN DOVER, DE, AND WINCHESTER, VA, I DEPARTED CHANDELLE ARPT HEADED FOR WINCHESTER. THIS WAS A VFR FLT THAT NECESSITATED NAVING NEAR AND POTENTIALLY THROUGH CLASS B AIRSPACE IN THE BALTIMORE AREA. I CALLED FSS TO FIND OUT ABOUT TFRS IN THE AREA AND ANY OTHER RESTRS OR ENHANCEMENTS TO THE AIRSPACE. ABOUT 10 MI FROM THE CLASS B AIRSPACE AS DEPICTED ON MY SECTIONAL CHART, I RADIOED BALTIMORE APCH. AFTER CALLING THEM A NUMBER OF TIMES, I DID NOT HEAR A REPLY TO MY CALL. THE AIR WAVES WERE EXTREMELY BUSY WITH MUCH STATIC AND VARIOUS OTHER CALLS BEING STEPPED ON. I REMAINED CLR OF THE CLASS B AIRSPACE GOING JUST UNDERNEATH THE RING AND GENERALLY IN THE DIRECTION I NEEDED TO GO. HOWEVER, DUE TO THE CONGESTION OF AIRSPACE IN THIS AREA, I PURSUED A CLASS B TRANSITION. FINALLY I BEGAN TO GET A LITTLE NERVOUS. IT WAS THEN THAT I REALIZED THAT THE SECTIONAL CHART WHICH I WAS USING FOR NAV WAS OUT OF DATE. I HAD INADVERTENTLY GRABBED 1 OF 2 SECTIONALS FOR WASHINGTON. I ALWAYS KEEP OLDER SECTIONALS AROUND TO MARK UP WITH PEN AND PENCIL, KEEPING THE NEWER ONES CLEAN AND MORE READABLE. THE ONE I MISTAKENLY SELECTED WAS INDEED OUT OF DATE (BY 8 MONTHS -- IT WAS THE PRECEDING CHART THAT HAD BEEN ISSUED). IN THE CONFUSION OF MAKING RADIO CALLS UNANSWERED, NAVING COMPLEX VFR AIRSPACE, STAYING CLR OF CLASS B AIRSPACE, ETC, I WAS ALSO USING AN OUT-OF-DATE CHART. I THEN ASKED MY FRIEND (WHO WAS ASLEEP) TO HELP ME OUT AND LOOK FOR THE CURRENT CHART WHICH I KNEW WAS IN THE PLANE. HE FINALLY FOUND IT AFTER SEVERAL MINS. JUST ABOUT THAT TIME I HEARD A RADIO CALL FROM APCH LOOKING FOR AN ACFT SQUAWKING 1200. I ASSUMED THAT THE CALL WAS MEANT FOR ME -- THE RETURN RADIO CALL FROM APCH. MY FRIEND AGAIN HELPED OUT AND ANSWERED THE CALL AND OBTAINED A SQUAWK CODE FOR ME. I STUDIED THE MORE UP-TO-DATE CHART AND WAS SHOCKED TO FIND THAT THE DC ADIZ INCLUDED THE AREA IN WHICH I WAS FLYING! -- NOT SO WITH THE PREVIOUS SECTIONAL CHART. I HAD ENTERED THE ADIZ WITHOUT OBTAINING A SQUAWK CODE AND HAD PROCEEDED ABOUT 5 MI INTO IT BEFORE GETTING A CODE. SHORTLY THEREAFTER, THE VOICE ON THE RADIO ASKED ME TO CALL A PHONE NUMBER ONCE WE LANDED. AGAIN MY FRIEND MADE THE CALL TO EXPLAIN WHAT HAD HAPPENED, AS HE IS MORE EXPERIENCED THAN I WHEN IT COMES TO THIS TYPE OF MATTER AND I, REALIZING THAT I HAD MADE A FLT INTO ADIZ AIRSPACE, THOUGH JUST A SHORT WHILE, WAS VERY SERIOUS INDEED. MY FRIEND CALLED THE NUMBER, BUT RATHER THAN LISTEN TO HIS EXPLANATION THEY SIMPLY ASKED FOR AND WERE GIVEN HIS NAME AND PLT CERTIFICATE NUMBER. ACTUALLY HE TRIED TO EXPLAIN THAT I WAS PIC BUT THEY APPARENTLY WERE SO BUSY AND RUSHED THEMSELVES THAT HE COULD NOT GET A WORD IN EDGEWISE AND SO IT WAS LEFT AT THAT. THEY PROBABLY ASSUMED THAT HE WAS PIC. HOWEVER, I HAD PLTED THE PLANE INTO AN ADIZ BY VIRTUE OF HAVING REFED THE WRONG CHART AND DID NOT HAVE THE SIT CORRECTED UNTIL I RECEIVED A SQUAWK CODE ABOUT 5-10 MI INTO THE ADIZ. I NEVER DID GET A CLASS B TRANSITION. I REMAINED ON THE CODE UNTIL EXITING THE ADIZ. I KNOW THAT ANY FLT INTO SUCH AN AIRSPACE IS VERY SERIOUS. HOWEVER, I CAN SEE THAT WITHOUT UP-TO-DATE INFO OF ALL KINDS THAT SUCH AN EVENT IS POSSIBLE.
