Interstate Cadet

The Interstate Cadet, produced by the Interstate Aircraft and Engineering Corporation from 1946 to 1951, was a modest yet versatile two‑seat trainer and sport aircraft that exemplified post‑World‑II general aviation growth. Developed from the earlier WT‑6 Super Culver design, the Cadet featured a low‑wing, all‑metal fuselage, a fixed tailwheel landing gear, and a 90‑horsepower Continental C‑90 engine that delivered reliable performance for flight‑training, aerial photography and personal recreation. Its spacious cockpit, dual controls and forgiving handling made it popular with flight schools, while the simple, robust construction kept operating costs low for private owners. Over 600 examples were built, many serving as liaison aircraft for the U.S. Army National Guard and as utility planes in remote areas of North America. The Cadet’s significance lies in its role as one of the first postwar aircraft to bridge the gap between wartime trainers and the emerging market for affordable civilian flying, influencing later designs such as the Piper PA‑18 Super Cub. Today, preserved Cadets are prized by collectors and vintage‑aircraft enthusiasts for their elegant lines and historical contribution to the democratization of flight.
