Analysis

A witness reported that this ultralight was 1 of 3 that took off on rwy 18, then turned 180 deg to a northerly heading. He reported that the ultralight was in level flt at aprx 200 ft when it suddenly pitched nose down, then it nosed up. At about that time, he noticed that the left wing was partially broken & the outermost part of the wing was flapping independently from the motion of the rest of the acft. The witness stated that the ultralight entered a steep nose down attitude, became inverted & crashed. Reportedly, the accident occurred when 1 of the wing support wires separated.
