TheI-11was a two-seat civil utility aircraft manufactured inSpainin the 1950s. Originally designed by the Spanish aircraft companyIberavia,its first (of two) prototype flew on 16 July1951.It was a low-wingmonoplaneof conventional configuration with fixed, tricycleundercarriageand a large,bubble canopyover 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 byAISA.
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 ataildraggerarrangement. This configuration entered production in1952with an order from the Director General for Civil Aviation for 70 aircraft for use in Spain's aeroclubs. TheSpanish Air Forcethen ordered 125 for use intrainingand liaison roles.
The Air Force then requested 200 aircraft built with the seats in tandem, which were designatedI-115by the manufacturers powered by a 112 kW (150 hp) ENMA Tigre inverted air-cooled engine.[1]
