Work on the design of the Dinfia IA 46 aircraft began by Argentine aircraft manufacturers back in 1955, while, to create the popularity of this aircraft, the developers had to redesign the aircraft several times. Initially, it was assumed that the plane would become a two-seater and go into use by both private owners and schools for training future pilots, however, later it was decided to expand the scope of this aircraft, so that it could already accommodate up to three people, the plane was suitable for training pilots, transporting goods, as well as for processing agricultural land. Later, the aircraft was also used for other purposes, in particular, for accelerating gliders and other aircraft moving due to ascending air currents.

Over the entire period of production, was built 133 aircraft of this model, including 17 aircraft presented as modified versions, and, despite the almost 60-year history, the aircraft continues to operate to this day - according to 2013 years, we are talking of at least 42 aircraft.

The cockpit of the Dinfia IA 46 is designed for the reception of three people - one pilot and two passengers, while taking into account the multipurpose use of this aircraft, a useful cargo can be placed on board the aircraft instead of passengers, or about 400 liters of chemicals if speech It is about the use of aircraft as agricultural machinery for processing fields. The maximum flight distance of the Dinfia IA 46 is very limited, and is only 650 kilometers, so even local carriers have not used the aircraft for commercial purposes. Later, this aircraft began to be used by the Argentine Air Force to carry out observation flights, however, already in 1965, it was withdrawn from use because of the limited range of the flight.

As a power plant, a Lycoming O-320-A2B four-cylinder piston aircraft engine is used here, capable of developing a thrust of 150 hp, which in turn provides the aircraft with a maximum flight speed of 180 km / h.

The main production version of the aircraft is Dinfia IA 46 Ranquel, but, in addition, has been carried out, and also the release of two modified versions. In particular, we are talking about:

  • Dinfia IA 46 Super Ranquel - improved version equipped with Lycoming O-360-A1A engine;
  • Dinfia IA 51 Techuelche - Version of 1963 years, with increased fuel capacity and strengthened fuselage.
