09/30/2007. Remarks by Jack Mckillop: "This aircraft was a new bomber design and was originally equipped with 600 hp Curtiss liquid-cooled engines. It made its first flight on November 5, 1931. Only one Model 214 was built, a second aircraft, the Model 215, was identical except for being equipped with 575 hp Pratt & Whitney R-1860-13 radial engines. After testing at the Boeing plant in Seattle, Washington, and at Wright Field, Dayton, Ohio, this aircraft was re-engined with 575 hp Pratt & Whitney R-1830-11 Hornet supercharged radial engines. The aircraft is shown in the markings of the Wright Field Depot.

The USAAC also purchased five Model 246 Y1B-9As for service testing. These aircraft were similar to the Models 214 and 215 but used three-bladed propellers, metal covered flight controls and had many internal changes. They were delivered between July 1932 and March 1933. The B-9 was never ordered into production."
