What happened
According to the owner of the experimental amateur-built light sport airplane, the non-certificated accident pilot was planning to only taxi the airplane and not get airborne due to the wind conditions. The owner and several witnesses observed the airplane depart the runway and fly the prescribed runway traffic pattern. While on the base leg, the airplane began a steep bank with the nose entering a dive. The airplane subsequently impacted the ground behind a row of trees, with the engine continuing to operate at high power until ground impact. Postmortem toxicology testing was consistent with recent use of an impairing prescription narcotic medication, although the source of blood tested made it impossible to accurately estimate the time of the most recent use or the likelihood of impairment. The autopsy revealed that the pilot had an active hepatitis C infection with early evidence of liver cirrhosis. It is possible that the pilot was impaired by his recent narcotic use, by symptoms of chronic active hepatitis C infection, or by some other condition for which he was taking the prescription narcotic medication.
