Role	Sport aircraft
Manufacturer	Homebuilt

The Davis DA-5, a.k.a. DA-5A, is a single-seat sport aircraft designed in the United States in the 1970s and marketed for homebuilding. Like designer Leeon D. Davis's successful DA-2, it is a low-wing monoplane with fixed tricycle undercarriage and a V-tail, but with a much narrower fuselage accommodating only the pilot, and a lengthened nose. Design work was carried out in 1972, but the prototype was not built until 1974, when it was completed in only 67 days.
