Year of design<br />
The year of design, as derived from the model name, is recorded in Figure 29. This<br />
shows that a large number of ABE <strong>aircraft</strong> designs owned by respondents were<br />
older than 40 years. Designs have been introduced in certain years, <strong>and</strong> the exact<br />
reason for this remains unclear. It may reflect periods of economic growth, or<br />
opening of a gap in the ABE <strong>aircraft</strong> market for a new design. Pattillo (1998)<br />
suggests that an entrepreneurial spirit <strong>and</strong> war drives changes in GA <strong>aircraft</strong> rather<br />
than the market in general.<br />

Type of engine<br />
Respondents chose three different types of engines when purchasing an ABE<br />
<strong>aircraft</strong>; these were certified <strong>aircraft</strong> engines, non-certified <strong>aircraft</strong> engines, <strong>and</strong><br />
automotive engines. The type of engine in this survey is recorded in Figure 30.<br />
This shows that the majority of <strong>aircraft</strong> had certified <strong>aircraft</strong> engines. Details about<br />
the engine were not requested, <strong>and</strong> it is not known if the engine installed into the<br />
<strong>aircraft</strong> was second-h<strong>and</strong>.<br />
Figure 30: Type of <strong>aircraft</strong> engine<br />
A certified <strong>aircraft</strong> engine is one that meets the requirements of the Federal<br />
Aviation Regulations (FAR) Part 33, or their equivalent. The engine is purchased as<br />
a complete product <strong>and</strong> installed into the <strong>aircraft</strong>. Historically, the major<br />
manufacturers for certified engines were Textron-Lycoming <strong>and</strong> Teledyne-<br />
Continental, with more recent entrants into this arena including Bombardier-Rotax<br />
<strong>and</strong> Jabiru.<br />
