| In 1991, the National Aeronautic and Space Administration (NASA) conducted a study to ascertain the estimated reliability of General Aviation aircraft. This information was to be used to aid in the development of new technology for next generation personal aircraft.; The purpose of this study is to attempt to reproduce the results of the NASA study, using a more homogenous population of flight training aircraft while eliminating factors included in the original NASA study that were not considered flight critical factors, such as paint reliability and auto-piloting devices. The failure results of the flight training aircraft were then compared to the revised NASA data from the original study.; Failure data from twenty eight (28) aircraft were gathered and processed using the two parameter Wiebull distribution. It was found that the modified NASA reliability data and the data gathered from the flight training aircraft did not differ significantly, and the removal of non flight critical factors from the NASA data also did not significantly change the results. |
