The I.Ae. 22 DL was an Argentine advanced training aircraft designed by the Instituto Aerotecnico (AeroTechnical Institute) in 1943, with a wooden structure, which resembled the North American NA-16.

Development

The I.Ae. 22 DL was a development of the I.Ae. D.L. 21, which itself was itself developed from the North American NA-16, at that time in service with the Argentine military.

Juan Perón flew over Córdoba in the I.Ae.22 "DL" prototype, 1944.

Argentine experience with the NA-16-4P and deteriorating political relations with the US led to the local development of the I.Ae. D.L. 21, which shared the NA-16 fuselage structure. However it proved too difficult to produce and an entirely new design (the I.Ae. D.L. 22) of similar configuration, but structurally different and optimized to available materials was built instead.[1]

It had a wooden structure, and a nine-cylinder 450 horsepower (340 kW) I.Ae. 16 El Gaucho radial engine with a Hamilton Standard 2M-D-30 metallic propeller.

The prototype flew on 8 August 1944,[2] although some sources give 14 May 1944.[1] Approximately 200 aircraft were built. A version with a 475 horsepower (354 kW) Armstrong Siddeley Cheetah 25 radial engine and a Rotol constant speed propeller was designated I.Ae. 22- C.
