The Luscombe 4 was a civil utility aircraft produced in small numbers in the United States in the late 1930s.

In 1936, Luscombe designed and began flying a simplified version of the Phantom known as the Luscombe 90, or Model 4. Much of the Phantom's complex compound-curved sheet metal was eliminated in favor of simplified single-curved sheets, and the hand-formed fairings were eliminated. Performance was not impressive.
