I.Ae. 22 DL

The '''I.Ae. 22 DL''' was an Argentine advanced training aircraft designed by the Instituto Aerotecnico (AeroTechnical Institute) in 1943. It had a wooden structure, and a 9-cylinder 450 HP radial engine (I.Ae. 16 El Gaucho) with a Hamilton Standard 2M-D-30 metallic propeller. The prototype flew the 8 August 1944, although some sources give 14 May 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. Approximately 200 aircraft were built. A version with an Armstrong Siddeley "Cheetah" 25 engine (radial 7 cylinder, 475 HP) and a Rotol constant speed propeller was designated '''I.Ae. 22- C'''.
