The
I-11 was a two-seat civil utility aircraft manufactured in
Spain in the 1950s. Originally designed by the Spanish aircraft company
Iberavia, its first (of two) prototype flew on 16 July
1951. It was a low-wing
monoplane of conventional configuration with fixed, tricycle
undercarriage and a large,
bubble canopy over the two side-by-side seats. Flight characteristics were found to be pleasing, but before plans could be made for mass production, Iberavia was acquired by
AISA.
The new management decided to continue with development, but made a few changes to the design, reducing the size of the canopy, and replacing the undercarriage with a
taildragger arrangement. This configuration entered production in
1952 with an order from the Director General for Civil Aviation for 70 aircraft for use in Spain's aeroclubs. The
Spanish Air Force then ordered 125 for use in
training and liaison roles.
The Air Force then requested 200 aircraft built with the seats in tandem, which were designated
I-115 by the manufacturers powered by a 112 kW (150 hp) ENMA Tigre inverted air-cooled engine
