Windecker Eagle
# Windecker Eagle

The Eagle AC-7 Eagle 1 (USAF designation YE-5) is an aircraft that was manufactured by Windecker Industries. It was the first composite airplane (foam and fiberglass construction) to receive FAA certification in December 1969 at a reported development cost of US$20,000,000. The fiberglass process was named "Fibaloy" by Windecker.

## Design and development

The Eagle's fuselage was molded in two pieces that were joined down the middle. The first prototype had a fixed undercarriage but the second, known as the Eagle 1, had retractable tricycle gear. This aircraft first flew on 26 January 1969. One prototype spun in on testing.

Only eight Eagles were produced before production ended when the company ran out of money.

No Eagle had been flying for many years, but one was restored and flown in December 2015, by Don Atchison, Mike Moore and a team commissioned by Chinese entrepreneur Wei Hang. Wei Hang holds the rights and the type certificate and plans to produce the aircraft in China for Asian sales.
