The DINFIA IA 35 Huanquero was a 1950s Argentine twin-engined general-purpose monoplane aircraft built by the DINFIA.

Development

The IA 35 Huanquero was the first aircraft design from the DINFIA organisation (Argentina) to enter production. A twin-engined all-metal (except for fabric-covered ailerons) low-wing cantilever monoplane, it had a high-mounted tailplane with two fins and rudders and retractable tricycle landing gear. It was powered by two I.Ae. 19R El Indio^[1] radial engines.

The design team was led by professor Kurt Tank, former Focke Wulf designer who also designed the Pulqui II jet fighter based on the Focke-Wulf Ta 183 of the World War II era.

The prototype first flew on 21 September 1953 and was followed by a planned production batch of 100 aircraft.^[2] The first production aircraft flew on 29 March 1957^[2] but less than half of the aircraft were built when production ceased in the mid-1960s.
