Title: Descriptive epidemiology of 2007 homebuilt aircraft accidents and accident and fatality rates
Author: Gregory Giancarlo Shaskan
Abstract: Abstract : Homebuilt aircraft are those that the builder has completed at least 51 % of the construction themselves . From 1993 National Transportation and Safety Board data , homebuilt aircraft made up only 3 % of the flying hours but were involved in 10 % of the general aviation accidents in the United States . This research investigates if and how these rates have changed over the past 15 years . The National Transportation and Safety Board Aviation Accident Database and Synopses website was queried for all types of United States homebuilt accidents during 2007 . Select variables were used to compare homebuilt accidents and fatality rates with non -homebuilt aircraft rates . Human and mechanical errors were implicated in homebuilt accidents similar to non -homebuilt general aviation accidents . Homebuilt accident rates per 100 ,000 flight hours are significantly higher than non -homebuilt accident rates (26 .44 +3 .36 vs . 4 .89 + 0 .29 , p <0 .001 ) Homebuilt fatality rates per 100 ,000 flight hours are also significantly higher (8 .67 + 1 .92 versus 1 .56 + 0 .16 , p <0 .001 ) . Safety efforts that focus on human and mechanical factors may reduce overall accident rates of both homebuilt and non -homebuilt aircraft .
