Designed in 1934 in response to a Spanish Air Force requirement as part of its modernisation programme, the Chirta was a conventional sesquiplane, constructed of wood and metal and seating the student and instructor in tandem open cockpits.

The tailskid undercarriage had faired wheels on V-form main legs.

The Chirta was intended to undertake fighter training and to be fully aerobatic.

[1] Though the exact date of the first flight of the Chirta is not known, by early July 1935 it was flying and sufficiently developed to have taken part in competitive trials for the trainer contract.

No further examples were built, though the prototype survived undamaged until at least November 1936, when Francoist forces captured Cuatro Vientos, where the trials had taken place.
