Bellanca Y1C-27 Airbus

The Bellanca Y1C-27 (later C-27) was a single-engine, high-wing transport adopted by the U.S. Army Air Corps in the early 1930s. Built by the Bellanca Aircraft Corporation of New Castle, Delaware, it was the military version of the company's Airbus, a rugged "workhorse" designed to carry passengers or cargo. The Air Corps purchased four Model SP-200 Airbus aircraft in 1933 as Y1C-27s, followed by ten improved C-27As; in 1934 most were re-engined with a 750 hp Wright Cyclone and redesignated C-27C.

The Bellanca offered better load capacity and performance than the Ford and Fokker transports it competed with, and its distinctive lifting-strut wing arrangement gave good short-field ability. The C-27 series served through the 1930s in the utility-transport role before being superseded by larger twin-engine types and ultimately the Douglas C-47.
