Analysis

The plt possessed a student plt & 3rd class medical certificate. After takeoff, he circled over the airfield, then climbed to about 200 ft AGL. A high school classmate stated that the ultralight then entered a nose high attitude & appeared to enter a practice stall maneuver. Based on witness observations, the ultralight entered this maneuver from about 150 to 250 ft AGL. The ultralight then went into a nose low attitude & crashed. No evidence of a preimpact failure/malfunction of the ultralight was found.
