The pilot was returning to the airport to land on runway 8. He stated that he overshot the final approach and had to maneuver the airplane back to the final approach course. The airplane was high on the approach so he extended 30 degrees of flaps and descended at an airspeed between 80 and 85 knots. The pilot stated that he felt that the approach was not stabilized; however, he continued the approach and landed. During the landing roll the pilot felt that he was being pushed by a strong tailwind and was unable to stop the airplane before the end of the runway. The airplane departed the runway environment to the right, went down a 65 foot embankment, and came to rest inverted, resulting in substantial damage to the airframe and both wings. The pilot stated that there were no mechanical anomalies with the airplane prior to the accident. Wind at the time of the accident was recorded as 340 degrees at 4 knots.
