Figure 48: Number of aircraft built 3.5.2 Type of build process Plans-built, slow-build, fast-build kit Figure 49 records the method used to build the ABE aircraft where the respondent had both built and flown an ABE aircraft (N=268). About 50 per cent of respondents constructed slow-build kit aircraft, while plans-built and quick-build aircraft accounted for about 25 per cent each of the remaining proportions. Data on construction method was not collected for second-hand aircraft. Of the 278 respondents who reported that they had both built and flown an ABE aircraft, 10 did not respond to this question. Figure 49: Method of construction used The decision to construct a plans-built aircraft is often made on the basis of cost and available resources (Cook, 2005). Although kit-build aircraft were offered for sale in the US in the 1920s and 1930s, it has been in the last 30 years that they have been used more extensively in Australia. Pre-fabricated parts in kit aircraft save time, but are more expensive. Because of the need to fabricate parts from scratch, a plans-built aircraft represent a significant challenge, starting with nothing but sheets of paper. Build time for different types of aircraft Aircraft can be built in three ways using plans, slow-build kits, and quick-build kit options. With a plans-build option, the builder usually fabricates all parts, except the engine. Kit aircraft are available as slow or quick-build options. Both slow and quick-build options have the same parts; the difference is that the wings and fuselage are largely complete with a quick-build option (Figure 50). Some respondents choose a combination of slow-build wings and quick-build fuselage. - 60 -
There is generally a trade-off between time and cost associated with building an aircraft. A greater degree of skill is required to fabricate parts from scratch, and the skills reflect the type of aircraft structure. Although kit aircraft such as the Ace Baby Ace, and the Flying Flea were offered in the 1920s and 1930s, the majority of aircraft built in Australia between 1955 and 1970 were plans-build options. After this point in time, aircraft kits began to appear such as the Glasair and Van’s. A number of kit manufacturers have used sales of kit aircraft to finance production aircraft certificates (Higdon, 1998).
