The student pilot reported that while taxiing his recently purchased, experimental light sport weight-shift control airplane on a residential driveway, he pushed the control bar forward, and a gust of wind lifted the airplane. He said that he was not intending to fly the airplane, but due to the gusty wind conditions, he elected to fly to the nearest airport instead of returning to the driveway. In his written report to the NTSB the pilot reported that he encountered windshear while on a southwesterly approach to Runway 24, which “slammed me into the ground.” The airplane sustained substantial damage. The pilot indicated that there were no preaccident mechanical problems with the airplane, and noted in his written report that the accident could have been avoided if he had not been taxiing the airplane in gusty wind conditions, with little previous flying experience. At the time of the accident a nearby aviation weather reporting station reported winds to be 260 degrees at 14 knots.
