Development and construction

The intention was to create a light aircraft suitable for aeroclub and agricultural use, and the resulting design was a conventional high-wing strut-braced monoplane with fixed tailwheel undercarriage. The aircraft were named for the Ranquel and Tehuelche peoples, different groups indigenous to Patagonia.

The state-owned Dinfia organisation commenced production of the Ranquel at Cordoba in 1958. Construction was of a fabric-covered tubular structure, although the Tehuelche featured metal-covered wings. Accommodation was provided for a single pilot and a passenger in tandem configuration. In all, some 132 aircraft were built, some of which served as glider tugs for the Fuerza Aerea Argentina.

Production ended in December 1968.

Operational history

Examples of the IA.46 have served aero clubs from 1958 to date, with several remaining in operation in the late 2000s.
