The pilot said he was landing at his private airstrip, and the wind drifted the airplane to the right of the landing tracks. He said the brush to the side of the tracks had not been cut, and was higher than normal. He said when the airplane encountered the brush during the landing roll, it nosed over. The pilot said the airplane sustained damage to one wing, the lift struts, rudder, landing gear, and fuselage. He said the wind may have been gusting to as high as 20 knots.
