Amateur-Built <strong>Aircraft</strong><br />

The amateur-built aircraft fleet includes a wide variety<br />
of designs <strong>and</strong> technologies, <strong>and</strong> covers the full<br />
range from simple, low-performance pleasure craft<br />
to high-tech, high-performance models. Most are<br />
single-engine. <strong>Pilots</strong> of amateur-built aircraft represent<br />
the full range of experience <strong>and</strong> certification.<br />
226 amateur-built aircraft were involved in accidents,<br />
<strong>and</strong> 55 (24.3 percent) of these were fatal.<br />
All were single-engine <strong>and</strong> 205 (90.7 percent) had<br />
fixed gear (including 10 seaplanes or amphibians).<br />
A total of 102 (including three with retractable<br />
gear <strong>and</strong> one amphibian) had conventional l<strong>and</strong>ing<br />
gear (Figure 42).<br />

Figure 43 tracks the proportion of accidents in<br />
amateur-built aircraft to overall GA accidents over<br />
the last ten years. Total amateur-built accidents<br />
continue to increase.<br />
The accident factor distribution is not markedly<br />
different from that in manufactured airplanes, with<br />
the exception of a somewhat higher proportion of<br />
maneuvering accidents (Figure 44).<br />
