History
First flight	24 May 1958

The Davis DA-1 was a light aircraft designed in the United States in the 1950s which never progressed beyond the prototype stage. Davis tried to bring the plane to market as a certified aircraft (his goal was a selling price of under $10,000), but was not successful.

Design and development

Davis constructed his DA-1 starting on 24 April 1957. It was a strut-braced high-wing single-engine all-aluminum airplane designed around the new Lycoming O-360 engine. The fixed-nosegear-equipped piston-engine DA-1 was of otherwise conventional configuration, but its V-tail was similar to that of the contemporary Beechcraft Bonanza, whose high cruise speed was attributed partly to its use of that empennage type.

Wings and tail surfaces of the DA-1 used external heat treated ribs; those surfaces were non-tapered (i.e. of constant chord).

Power for the DA-1 was a horizontally opposed Lycoming O-360 of 180 hp (134 kW), which gave a top speed of 125 mph (201 km/h).

Operational history

Initial test flights showed that there was not enough elevator authority with full flaps, and the plane was very loud. Soundproofing, and aerodynamic modifications were applied.
