| 摘要： | "Public aircraft" are aircraft operated for the purpose of fulfilling a government function that meet certain conditions specified under Title 49 United States Code, Section 40102(a)(37). The Safety Board identified 341 public aircraft accidents that occurred during the years 1993-2000. Using activity data from the Federal Aviation Administration (FAA) (for the period 1996-1999), the Board calculated an accident rate of 3.66 accidents per 100,000 flight hours for nonmilitary, nonintelligence public aircraft. Using activity data from the General Services Administration (also for the period 1996-1999), the Board calculated an accident rate of 4.58 per 100,000 flight hours for nonmilitary, nonintelligence Federal aircraft. Both rates were lower than the general aviation accident rate (7.2 accidents per 100,000 flight hours), but higher than the accident rate for air taxis (3.47), scheduled Part 14 CFR 135 operations (1.06), or 14 CFR Part 121 operations (0.30). Comparisons between public and general aviation accidents revealed similar proportions of broad causal factors. However, accidents in these two sectors differed in other ways. A higher proportion of public aircraft crashed during local flights, at off-airport locations, and during maneuvering phases of flight. Also, accident-involved public aircraft pilots were more likely than accident-involved general aviation pilots to hold advanced ratings. Limitations and flaws associated with the FAA's nonairline activity estimates made it impossible for the Board to make carefully controlled comparisons of the safety of public versus civil aircraft. The data were not sufficiently detailed to support the calculation of public and civil aircraft accident rates for specific purposes of flight (for example, aerial observation, aerial application, and so on). Furthermore, FAA flight hour estimates are potentially biased because they are based on a survey that is administered to a sample of aircraft owners listed in the FAA's Civil Aircraft Registry, which is known to contain many outdated or inaccurate records. As a result of these findings, the Board made safety recommendations to the Federal Aviation Administration and the General Services Administration. |
