The non-rated plt had purchased the ultralight vehicle about 1 month prior to the accident. He had completed aprx 8 hrs of taxi & low flts along a grass rwy. Earlier on the day of the accident, he had made 2 flts & reportedly had accumulated 1 hr of flt time in the ultralight. On the 3rd flt, he took off from the mansfield muni arpt to reposition the ultralight to a golf course, about 3 mi away. A witness observed the ultralight approaching a fairway & reported it appeared low as it approached trees. He reported that the nose pitched up sharply, the left wing lowered & the ultralight began to lose altitude as the nose lowered in the vicinity of a house. He reported that the nose pitched up again, then the ultralight lost altitude rapidly & disappeared behind trees and crashed. No preimpact failure of the ultralight or its eng was found. The plt had had aprx 7 hrs dual flt instruction in a conventional acft, but his 1st solo flt was in the ultralight.
