The Howard DGA-18 was an American two-seat basic training aircraft designed and built by the Howard Aircraft Corporation for the United States Civil Pilot Training Program.[1]

Design

The United States' Civilian Pilot Training Program resulted in high demand for both primary and advanced training aircraft, and in an attempt to take advantage of this demand, the DGA-18 was designed, with the first example flying in October 1940.[2][3] The DGA-18 was a low-wing cantilever monoplane with two tandem open cockpits and a fixed conventional landing gear. The aircraft was built in three variants with different engines fitted.[1]
