Narrative:

After announcing on CTAF that I was 9 miles south of airport and inbound; I smelled something burning. I started to shut some non-important items off like lights; when I started to see smoke come up from under the dash. As I turned off the master switch; I could see a small flame from near my left foot. I turned the fuel switch to the off position and searched for a landing area. The flame went out almost immediately. I noticed a paved county road below me and I landed into the small amount of wind that was present that day. A mechanic came to the scene and found one power wire had fallen from the wiring harness somehow and landed on a small fuel pressure hose (metal) and created an arc. Some wires burned and a pitot-static tube was damaged; since the airspeed indicator went dead sometime after I took off from the road and returned to the airport. Due to training; I knew to immediately shut off fuel for a fire; shut down electricity and find a place to land. This plane has a 28 volt electric system; so no circuits tripped.
