Narrative:

Was flying from charlottesville-cho-to danburg, ct,-dxr-via direct frederick-pdk-direct lns-direct dxr. Thought I was above washington TCA, when I sighted a plane descending into dulles at about 1 mi ahead of me. Plane was going west to east, I was going northeast. To give more clearance, I made a climbing turn to the west so as to pass behind him. After I was clear of the other plane, I proceeded on a course to lancaster. I called baltimore approach about 30 mi out and at 9500' MSL to get flight following to danburg, at which time I was told to give the supervisor at dulles a call when I landed. Called supervisor at X:15 pm, 6/91, and was told that I had passed through the top of the TCA at 9500'. I did not realize that I was in the TCA. My last flight through that section dulles was still an arsa. When he asked about the other aircraft, I told him I had the airliner in sight and went behind and above him as I saw he was descending. Just had major repairs done to my plane and was watching engine gauges more than flight instruments.
