The sport pilot departed in his single-engine experimental airplane for a local flight. Shortly after takeoff, a witness observed the airplane make a sharp (hard) right turn and nose dive straight into the ground. Another witness said the airplane departed with full power at a good rate of climb and speed, followed shortly after by the sound of "normal" power reduction. The airplane came to rest in a field adjacent to the runway and was destroyed by post-impact fire. The pilot purchased the airplane approximately four months prior to the accident and had logged approximately 22 hours in the airplane, which had accrued a total of 50 hours. An invoice dated a month prior indicated that the pilot had purchased wing skin and rivets for the left wing. However, it could not be determined if any work had been done to the left wing prior to the accident because the maintenance logbooks were not made available for review. Toxicological testing was conducted by the FAA Toxicology Accident Research Laboratory, in Oklahoma City, Oklahoma. The report of testing noted negative results for carbon monoxide, cyanide, ethanol, and drugs. The report noted 6200 mg/dl of glucose in urine, 0 mg/dl of glucose in vitreous fluid, and 9 percent Hemoglobin A1C. According to the toxicological report, "Elevated postmortem urine glucose levels could be caused by diabetes mellitus or several other medical conditions, which may or may not have been a factor in the accident." The FAA had no record of application for airman medical certificate for the pilot since 1992. No medical certificate is required for operation under sport pilot regulations.
