[2] The 14-7 was a modern, low-wing cantilever monoplane with a fuselage intended to contribute lift to the design.
The second prototype, a 14-9 flown by Bellanca test pilot Holger Hoiriis, did not recover well from spins.
Bert "Fish" Hassell took the 14-9 prototype to the 1938 Chicago air show and the difficulty people had boarding the aircraft resulted in the cabin door upper fuselage cut-out modification.
[6] In 1940, Bellanca Aircraft loaned the National Advisory Committee for Aeronautics (NACA) two 14-9s, purportedly for handling evaluations.
[7] Development culminated in the 1941 14-12-F3[8], at which point production ceased to allow Bellanca to work as a military subcontractor for the duration of the war when an attempt to market a militarized version as a trainer was unsuccessful.
