Aeronáutica Industrial S.A.

The predecessor company was founded by Jorge Loring Martinez in Cuatro Vientos near Madrid in 1924.[1] Aeronáutica Industrial S.A. was established in 1934 and through the course of the 20th century manufactured a number of light aircraft designs including Cierva autogyros.

In 1954, AISA purchased Spanish manufacturer Iberavia and took over the I-11 light plane project, eventually building around 400 examples. For a time it specialised in the maintenance and upgrading of helicopters. In 1982 it attempted, unsuccessfully, to market an autogyro design of its own, the GN.

The company was bought by CASA in 1995, but continues to operate under its own name.
