The Tachihi R-53 was amongst the first aircraft built in Japan after the relaxation of the ban imposed at the end of World War II. It is a parasol-wing, two seat, training aircraft powered by a British engine. Only one was produced.

Design and development

From the end of World War II until the passage of the Air Law in July 1952, aircraft manufacture in Japan was forbidden. The Tachihi R-52, the R-53's immediate predecessor, was the first post-war Japanese aircraft built with local materials and powered by a Japanese engine. It flew in September 1952, soon followed by the similar but Blackburn Cirrus Major powered R-53.

The R-53 is a parasol-wing monoplane. In plan its wing is unswept and has constant chord, with no flaps or leading edge slots; it is built around two spars made from Japanese cypress, with duralumin ribs and fabric covering. On each side there are two sets of wing struts to transfer loads to the fuselage, one an unequal length and angle X-form pair from the lower fuselage longerons to the wing spars, the other pair cabane struts from the upper fuselage to the wing centre section, leaning together. The fuselage has a welded steel tube frame, fabric covered, with rounded upper decking. There are two tandem open cockpits, one below the wing trailing edge and the other below mid-chord. The tailplane is attached to the top of the fuselage, with a trim tab on the elevator; the fin and rudder are curved, the fin extended forward by a lengthy fillet.

The R-53 is powered by a 155 hp (116 kW) Blackburn Cirrus Major four-cylinder inverted inline engine, distinguishing it from the short-nosed radial engine installation on the R-52. It has a fixed conventional undercarriage with mainwheels fitted with brakes on independent hinged V-form legs with oil spring shock absorbers in separate, more upright, struts from the X-intersection of the wing struts, made more rigid by a secondary strut to mid-fuselage. The tail wheel is steel sprung and steerable.

The first flight date of the R-53 is not precisely known, but it followed that of the R-52 (September 1952) and it was flying by April 1953.[5] The prototype JA3070 is the only one of its type recorded on the Japanese register before late 1955[5] so probably the only one built. It still survived in 2002, though in poor condition, stored in a garage at the Tachikawa works.[5]
