Davis DA-1




The Davis DA-1 was a light aircraft designed in the United States in the 1950s which never progressed beyond the prototype stage.

Leeon D. 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 a V-tail.

Wings and tail surfaces of the DA-1 used external heat treated ribs; those surfaces were of constant chord. DA-1 through DA-5 used the Clark Y airfoil.

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).

Registered N5822N, it was first flown on 24 May 1958, initial test flights showed that there was not enough elevator authority with full flaps, and the plane was very loud. Soundprofing, and aerodynamic modifications were applied. 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.
