The co-owner of the ultralight vehicle was watching the flt & observed the accident. He said the vehicle approached the pasture & was descending from aprx 200 ft as if the plt was going to land or fly by. The ultralight passed over the takeoff/landing area at about 30 to 40 ft AGL & continued at the same alt & general direction for aprx 200 yards, where it collided with tree branches. Several other witnesses corroborated what the co-owner had described. No preimpact deficiences of the ultralight were found. Four bottles of medication were found which included adapin, sinequan, thorazine, & nardil. The plt's doctor reported that he (the plt) had been treated for depression for several months & had periods of mental incapacitation. Autopsy & toxicological exams revealed nothing significant to the accident. The plt had no formal flt instruction toward certification, but had received 4 hrs ground school & 40 to 50 flts in an unpower vehicle towed behind an automobile & a supervised solo flt.
