The Curtiss O-40 Raven was a small American observation aircraft of the early 1930s, built for the United States Army Air Corps. Curtiss designed it as the Model 62 in response to a 1931 requirement. The first aircraft, the YO-40, was an all-metal sesquiplane, a biplane whose lower wing is much smaller than the upper, with a retractable tailwheel undercarriage and a Wright Cyclone radial engine, and its crew of two sat in tandem. It crashed in 1932, was rebuilt with stronger wings and an enclosed cockpit, and the four aircraft that followed were redesigned as monoplanes by removing the lower wing. Delivered in 1933 as the O-40B, they served with the 1st Observation Squadron until 1939. Performance and handling were good, but the Air Corps disliked the cockpit arrangement and low fuel capacity, so no more were ordered.
