The PT-22’s fuselage is a simple monocoque structure, with thick gauge alclad skin. The wings feature spruce spars, aluminum alloy ribs, steel compression members, with aircraft fabric covering aft to the trailing edge and aluminum alloy sheet covering from the leading edge to the spar.[1] The wings have 4° 10′ of sweep back, 3° of incidence and 4° 30′ dihedral

Operational History

The PT-22 was developed in 1941 from the civilian Ryan ST series. The earlier PT-20 and PT-21 were the military production versions of the Ryan ST-3 with a total of 100 built. The PT-22 was the United States Army Air Corps’ first purpose built monoplane trainer. The rapid expansion of wartime aircrew training required new trainers, and the Ryan PT-22 was ordered in large numbers. Named the “Recruit”, it entered operational service with the U.S. Orders also were placed by the Netherlands, but were never realized as the nation capitulated to Axis forces. The small order of 25 ST-3s was redirected to the United States and redesignated as the PT-22A. Another order also came from the U.S. Navy for 100 examples.
