Narrative:

I departed oxb approximately XA30 local time and contacted flight following. I advised that I was en route to W32 and that I had an frz flight plan on file with leesburg FSS to enter the ADIZ. I asked if they could check to make sure approach could locate the flight plan, so when I arrive at whino intersection I would be able to continue into the ADIZ and on to W32. Approach advised that the flight plan was located and directed me to proceed to whino. As I approached whino intersection approach handed me off to approach. I received a discrete transponder squawk and was directed to proceed as filed. I was still at 4500 ft MSL. At about 20 NM southeast of W32, I asked if I could start down. I was cleared to 2500 ft. As I reached 2500 ft I heard a loud buzzing noise in my headset and #2 radio and all other avionics shut down. My #1 radio began flashing on and off. I was approximately 15 mi from W32. I broadcasted in the blind that I had a total electrical failure and was declaring an emergency and that I had W32 in sight. I immediately performed an emergency landing gear extension and proceeded on 45 degree right base to runway 5 at W32 onto final and landed. Upon landing I called FSS and advised what had happened and I was given a number to call TRACON. I did and they told me that they thought it had an electrical failure. I did not comply with the established procedure because I was experiencing an emergency and I had W32 in sight. I did not think I was safe or prudent to turn around and exit the ADIZ. If additional information is needed, please contact me.
