A trio of I.Ae DL 22 two-seat advanced trainers in flight over Sierras de Cordoba. The DL 22 was an all-wood aircraft powered by one 450 h.p. El Gaucho nine-cylinder radial engine which gave a maximum speed of 180 m.p.h. at 1,500ft. The I.Ae DL 22 was built by the Institute Aero- tecnico (I.Ae) formerly known as the Fabrica Militar de Aviones, a company established in Cordoba in October 1927 which initially built aircraft under licence. In 1932 I.Ae began building aircraft of its own design.

I.Ae DL 22 Ea 730 after a forced landing. Judging by the absence of propeller blades the trainer hit the ground with fairly high engine revs.

Another DL 22, Ea 724, actually in one piece. Note the similarity to the NA-16.

A couple of camouflaged DL 22s with some of the local gentry assembled in front.

A factory-fresh DL 22C, 841, photographed in 1944. The 22C was powered by the 475 h.p. Armstrong Siddeley Cheetah and had a maximum speed of 190 m.p.h. at 1,500ft.
