The 1950 I-11 aircraft was followed by the I-115 basic trainer with revised fuselage. Originally designed by Iberavia S.A., series production was undertaken by Aeronautica Industrial S.A.
First flown on 16 July 1952, 450 were delivered overall. Construction is all wood. Full dual controls and instrumentation are fitted.
Two hundred were ordered for the Spanish Air Force during the mid-1950s, designated E.6, to replace the CASA-built Bucker Jungmann primary training biplane.
