摘要：	Biological samples collected from fatally injured pilots in aviation accidents involving all types of aircraft, including amateur-built aircraft, are submitted to the Civil Aerospace Medical Institute (CAMI) for accident investigation. These samples are analyzed for fire gases, ethanol, and drugs. Trends of amateur-built aircraft accidents and toxicological findings in the associated pilot fatalities have not been examined. Amateur-built aircraft accidents that occurred during 1990-2009 were evaluated by retrieving necessary information from the CAMI toxicology database. Probable cause and factor in the amateur-built aircraft mishaps were obtained from the National Transportation Safety Board's (NTSB's) aviation accident database. Of 6309 aviation accidents from which CAMI received postmortem samples, 979 (16%) were related to amateur- built aircraft. The highest number of aviation mishaps occurred during summer, which was true with amateur-built as well as with all other aircraft. There was a decreasing trend in accidents of non-amateur-built aircraft, whereas there was an increasing trend in accidents of amateur-built aircraft. In the 979 accidents (pilots), 392 were positive for ethanol and/or drugs. Ethanol was found in 29 pilots, drugs in 345, and ethanol plus drugs in 18. For ethanol/drug-related accidents also, a decreasing trend was observed with non- amateur-built aircraft and an increasing trend with amateur-built aircraft. Of the 392 amateur-built aircraft, 388 (99%) were flying under the general aviation category. In the 392 pilots, 238 (61%) held private pilot flying certificates and 260 (66%) third-class airman medical certificates. The spectrum of drugs found in the amateur-built aircraft accident pilot fatalities was consistent with commonly used drugs in the general population.
