Abstract:

During the twelve months ending October 31, 1965, there were 122 fatal general aviation accidents in the Western Region in which the Regional Flight Surgeons office was notified and the wreckage was located within one week. Autopsies were obtained in 86 pilots and blood alcohol determinations were obtained on 83 of these. No accidents were found to be definitely due to medical conditions but a psychiatric problem is the probable cause of one. In addition, 25 wore corrective lenses and 20 had other recorded physical defects. Drugs were found on three but were not found to be a causal factor possibly significant barbiturate levels were found in two accidents. Blood ethyl alcohol levels 30 mg were found in 17 20.5 five had levels greater than 250 mg . The relationships of experience, occupation, local reputation and time of day to alcohol involvement are discussed. Carbon monoxide, agricultural chemicals, and fatigue are among other causes found for fatal accidents.
