| 摘要： | The number of nonfatal and fatal general aviation accidents decreased from 1999 through 2011; more than 200 fatal accidents occurred in each of those years. Airplanes--particularly single-engine piston airplanes--flying personal operations were most often involved in accidents. Most general aviation accidents are attributed to pilot error and involved a loss of aircraft control. Some segments of the industry experienced accidents disproportionately to their total estimated annual flight hours. For example, among the airplane categories we reviewed, experimental amateur-built airplanes were involved in 21 percent of the fatal accidents but accounted for only 4 percent of the estimated annual flight hours. In another example, corporate operations were involved in about 1 percent of fatal accidents while accounting for 14 percent of estimated annual flight hours. We can draw some conclusions about general aviation accident characteristics, but limitations in flight activity and other data preclude a confident assessment of general aviation safety. The Federal Aviation Administration's (FAA) survey of general aviation operators, on which the agency bases its annual flight-hour estimates, continues to suffer from methodological and conceptual limitations, even with FAA's efforts to improve it over the years. To obtain more reliable data, FAA has discussed requiring that flight-hour data be reported, such as during annual aircraft maintenance inspections. FAA has set a goal to reduce the fatal general aviation accident rate per 100,000 flight hours by 10 percent from 2009 to 2018. However, given the diversity of the industry and shortcomings in the flight activity data, this goal is not sufficient for achieving reductions in fatality rates among the riskier segments of general aviation. Further, achieving the goal could mask continuing safety issues in segments of the community. |
