Abstract : A study and an analysis were made of the records on engine exhaust system malfunctions in the single engine type general aviation aircraft from the time period of 1958 through 1962 to determine the extent of the inflight hazards involving carbon monoxide poisoning, fire, power loss, etc. The results disclosed approximately 50 percent of the exhaust system failures occurred in the exhaust gas-to-air heat exchanger, 20 percent in the stacks or manifolds, and 20 percent internal to the muffler (baffles and diffusers). Nineteen illnesses and twelve fatalities out of 38 reported incidents of exhaust gases in the cabin were documented. Fourteen fires and 70 incidents of partial engine power loss or complete power failure were also reported. Analysis disclosed that the exhaust systems of newer aircraft fail at a markedly higher rate than the exhaust systems of older aircraft. (Author)
