"Entomology, the study of bugs, is not something that many of us consider when we go flying. Yet insects can wreak havoc on a variety of aircraft systems, and pilots probably don't pay enough attention to the small tubes, vents, and orifices that are present in every airplane. Looking through the Air Safety Foundation database over the past 25 years, we found more than 20 accidents attributed to insects in fuel vent lines, pitot tubes, carburetors, and other sensitive places. It's quite likely that there were some unexplained engine stoppages caused by insects blocking vents." - "Bugged" By Bruce Landsberg
