Coming in third place, at about 6 percent of GA accidents, is fuel management. There is actually some good news here. Accidents related to fuel management have been steadily declining during the past 10 years, from 159 in 1999 to only 73 in 2008. This is likely due to the influx of glass-cockpit airplanes that give the pilot a very accurate indication of how much fuel is on board and even provide range rings on moving map displays and automatic reminders to switch tanks. However, even the most advanced cockpit can't compensate for inadequate flight planning, failure to confirm how much fuel is on board before taking off, incorrect fuel system operation and failure to land for fuel when faced with unanticipated conditions. Since all of the general aviation flights analyzed by the Nall Report involved the use of fuel, we can estimate that a pilot who has a detailed understanding of his fuel system, carefully plans the fuel requirements for each flight, verifies the required fuel is on board and diverts for fuel when necessary will reduce his chance of an accident by around 6 percent.
