The '''Avtek 400A''' is an American prototype turboprop-powered business aircraft, which was developed in the early 1980s. Its configuration was unusual and distinctive : a low-wing monoplane with two pusher engines mounted above the wings, and a large canard mounted atop the forward fuselage. The aircraft's sleek, futuristic design earned it a guest appearance on the ''Airwolf'' TV series as the ''X-400'', which was used by the villain, Lou Stappleford in the ''Eagles'' episode.
The Avtek's structure made extensive use of advanced composite materials throughout.
In 1998, Avtek declared bankruptcy without the prototype having completed the testing required for US FAA type certification. The company's assets were purchased by AvtekAir, who {{As of|2004|lc=on}} planned to revive the project under the designation '''AvtekAir 9000T'''.
The only Avtek 400A constructed is currently owned by Evergreen Aviation & Space Museum, who are currently restoring the aircraft.<ref>{{cite web |title=Onward, Not Upward |url=https://www.thecamarilloacorn.com/articles/onward-not-upward/ |website=Camarillo Acorn |access-date=23 July 2025 |location=Agoura Hills, CA |date=April 5, 2025}}</ref>
