The Tachikawa Ki-17 was a basic training aircraft of the Imperial Japanese Army Air Force in the 1930s.
It was known to the Allies under the nickname of Cedar during World War II.
The Ki-9 was originally planned to be manufactured in two versions using the same basic airframe, but with different engines for service as either a primary or intermediate trainer.
However, when the lower-powered form proved to be unsuitable due a centre of gravity issue, design of a new airframe was ordered for the basic trainer version and was given the new designation of Ki-17.
Compared to the Ki-9, the Ki-17 had equal-span wings, a slimmer fuselage and a revised tailplane.
It was powered by a 112 kW (150 hp) Hitachi Ha-13a radial engine.
The first prototype flew in July 1935.
The only major change made to subsequent production aircraft was the deletion of the upper-wing ailerons to eliminate oversensitive control inputs
The Ki-17 was introduced to service as the Army Type 95-3 Basic Grade Trainer Model A under the former aircraft naming nomenclature system.
Tachikawa manufactured 560 Ki-17s between 1936 and 1943 and the type saw service with the Army Air Academy and flight training schools.
