Visual meteorological conditions prevailed at the time and no flight plan was filed. The airplane was substantially damaged and the student pilot, the sole occupant, was not injured.

The air traffic controller working the local position reported that the pilot was instructed to make a straight in approach to runway 32, and was cleared to land.
