Windecker Industries
Windecker Industries was an American aircraft manufacturer founded in 1962 as Windecker Research in Midland, Texas, by Leo Windecker, a dentist from Lake Jackson, Texas. In 1969, Windecker won Federal Aviation Administration (FAA) certification for the first-ever all-composite (fiberglass epoxy resin) aircraft, the single-engine Windecker Eagle.
==Early flight testing==
Initial tests of composite wings on conventional airplane bodies began in 1958. Full FAA-supervised structural and flight testing began in 1961. In 1965, the company delivered a pair of composite wings to Cessna Aircraft Company, where they were subjected to structural and flight testing on a Cessna 182.〔Dr. Leo Windecker, personal recollection〕 Results proved promising,〔However, the relatively thin fiberglass skins on those wings (designed as direct replacement for the all-aluminum wings of the Cessna 182 testbed) showed greater deformation under load than the aluminum skins〕 so the company built an experimental prototype of all-composite aircraft, the Windecker ACX-7 Eagle. Designed by Dr. Leo Windecker and his wife, Dr. Fairfax Windecker (also a dentist), the aircraft was molded from a unidirectional fiberglass called Fibaloy. The fuselage was made in two halves in full-size female molds and joined on the centerline, much as a model kit might be assembled; the wings were full-core foam around a tubular fiberglass fuel tank, with wing skins formed in full-size female molds. The first prototype, constructed in the Midland research center, flew in October 1967.
