Development and construction

edit

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.[2]

Operational history

edit

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