AvtekAir, Inc – Aircraft Involved
AvtekAir, Inc. was an American aircraft manufacturer based in Camarillo, California, that pursued an ambitious programme of advanced turboprop and turbofan business aircraft during the 1980s and 1990s. The company is best known for its radical canard pusher configuration, which placed the engines at the rear of the fuselage driving pusher propellers, with a forward canard surface providing pitch control. Despite significant engineering innovation and investor interest, AvtekAir ultimately failed to bring its designs to full production certification.

Historical Note
AvtekAir, Inc. was founded in the early 1980s with the goal of producing a new generation of high-speed, fuel-efficient business turboprops. The company's design philosophy centred on the canard pusher layout — a configuration that offered several theoretical advantages over conventional tractor-engine designs, including reduced cabin noise (engines behind the passenger cabin), improved aerodynamic efficiency, and a naturally stall-resistant canard foreplane.
The company attracted significant attention from the general aviation community and secured development funding through the 1980s. The Avtek 400A prototype flew and demonstrated the concept's viability, but the path to FAA certification under FAR Part 23 proved lengthy and financially demanding. The company reorganised and rebranded efforts under the AvtekAir name, pursuing both turboprop and turbofan variants of the basic design. Despite these efforts, full production certification was never achieved, and the company ceased operations in the 1990s.
AvtekAir's designs remain a notable example of the innovative — and commercially challenging — general aviation programmes of the 1980s, a period that saw numerous ambitious designs fail to survive the certification process and market conditions of the era.
Aircraft Involved
Avtek 400A
The Avtek 400A was the original technology demonstrator and prototype aircraft that established the AvtekAir canard pusher configuration. Key characteristics included:
- Twin turboprop engines in a pusher configuration mounted at the rear of the fuselage
- Forward canard surface for pitch control and stall resistance
- All-composite airframe construction for light weight and structural efficiency
- Seating for up to nine occupants (pilot plus eight passengers)
- High cruise speed targets in the 350–400 knot range, competitive with contemporary turboprops
- Retractable tricycle undercarriage
- Pratt & Whitney Canada PT6A turboprop engines
The 400A flew and demonstrated the aerodynamic concept, forming the basis for all subsequent AvtekAir development. It was intended to be developed into a certified production aircraft under FAR Part 23.
AvtekAir 9000T
The AvtekAir 9000T was a proposed turboprop development of the Avtek 400A concept, refined for production certification. The 9000T designation reflected the company's ambitions for a nine-place cabin turboprop in the high-performance business aviation segment. Design features included:
- Retention of the canard pusher configuration from the 400A
- Refined composite airframe with improved aerodynamic detailing
- Twin turboprop powerplant installation optimised for cruise efficiency
- Enhanced cabin interior for business aviation operators
- Targeting FAR Part 23 certification for commercial production
The 9000T represented AvtekAir's primary production programme during the late 1980s and early 1990s, but certification was not completed before the company's financial difficulties ended the programme.
AvtekAir Explorer
The AvtekAir Explorer was a proposed utility and multi-mission variant of the AvtekAir canard pusher platform, intended to broaden the aircraft's market appeal beyond pure business aviation. The Explorer concept targeted:
- Utility transport and cargo roles in addition to passenger transport
- Potential military and government operator markets
- Adaptable interior configurations for different mission profiles
- Retention of the composite airframe and canard pusher layout
- Enhanced range and payload capability compared to the business aviation variants
The Explorer remained at the proposal and design study stage and did not advance to prototype construction before AvtekAir ceased operations.
Turbofan Variants (Proposed)
AvtekAir also studied turbofan-powered variants of the basic canard pusher airframe, which would have replaced the turboprop pusher engines with small turbofan engines to achieve jet-level cruise speeds. These studies were sometimes referred to informally in aviation press coverage of the period but did not advance beyond preliminary design. A turbofan-powered AvtekAir would have competed directly in the Very Light Jet segment that later emerged in the 2000s.
Engineering Norms and Standards
AvtekAir's designs were developed to the following engineering and regulatory frameworks:
- FAR Part 23 — the applicable FAA airworthiness standard for normal, utility, acrobatic, and commuter category aircraft at the time of development
- Composite airframe construction — AvtekAir was among the early adopters of all-composite primary structure in the general aviation turboprop segment, predating the widespread adoption of composites in production aircraft
- Canard configuration aerodynamics — the design incorporated established canard foreplane theory to provide natural pitch stability and stall resistance, a configuration also explored contemporaneously by Beechcraft (Starship) and Scaled Composites
- Pusher propeller installation — the rear-mounted pusher configuration required specific propeller clearance, ground clearance, and engine-out handling analysis under FAR Part 23 multi-engine requirements
