The airplane was substantially damaged when it overran runway 08 (2,272 feet by 33 feet, asphalt) and impacted terrain during landing. The pilot stated that when he attempted the first approach to runway 08, he "felt a little fast so went around and set up for short field approach." On the second approach the airplane landed "on or shortly after the numbers" and the pilot reported that the braking was "inadequate." The airplane overran the end of the runway and subsequently impacted a dirt pile. A witness reported that the pilot "landed with a tailwind" and that the "wind sock [was] fully extended." Wind conditions reported at various airports surrounding the accident site were from 250 to 260 degrees true at 7 to 9 knots. An examination of the braking system after the accident revealed no anomalies and all serviceable components were within operational limits.
