The Model 309 was a Proof-of-Concept aircraft built for Adam Aircraft Industries of Denver, Colorado, by Scaled Composites. To provide a safe twin-engine aircraft, the centerline thrust configuration was chosen and the cabin was designed to carry a pilot and five passengers in pressurized comfort with an unpressurized baggage space in the nose, and the remainder of baggage stowed in the cabin aft of the rear seats. The tricycle landing gear was retractable with the trailing-link mains folding into the booms.

 

The outboard wings, horizontal tail, elevator, rudders and flaperons had no secondary bonds in their primary structure being produced as single cure parts. This allowed lighter, stronger and safer structure due to the significant elimination of fasteners and secondary bonds.

 

Conceptual design started in May of 1999, the first tool was cut late in August, and the first flight was on March 21, 2000. The aircraft was unveiled to a small group of guests on April 5, 2000. After a flight test and refinement program, the aircraft was delivered to Adam.
