Exposure to carbon monoxide (CO), which is formed by the incomplete combustion of carbon-containing materials such as aviation fuels, is associated with headache, dizziness, fatigue, and at elevated doses, death. Exhaust system failures in general aviation (GA) aircraft can result in CO exposure. When this occurs in an aircraft, the end result could be an accident
The Federal Aviation Administration tasked Wichita State University to conduct research that focuses on carbon monoxide safety issues as they apply to general aviation products. A technical report titled “Detection and prevention of carbon monoxide exposure in General Aviation Aircraft» that can be very useful to those engage in Avaition Safety.
The report shows that after researching National Transportation Safety Board (NTSB) accidents related to carbon monoxide (CO) poisoning, the muffler system was the top source of CO. For the CO-related cases where the muffler was identified as the source of the CO leakage, 92 percent had a muffler with more than 1,000 hours of service.
