Two manufacturers for one trainer
Deliveries of the aircraft to the USAAF, under the designation AT-10, began in February 1942. Beechcraft's production ended in 1943, by which time the company had delivered 1,771 AT-10s. Globe Aircraft Corporation built another 600 examples of the trainer before manufacturing stopped for good the following year. In total, the type was built between 1942 and 1944.
Wood instead of metal
Beechcraft met the requirement by designing an aircraft that would be built mainly of wood. The result was a version of the AT-7 made largely from that material.
Powerplant
The AT-10 flew with two air-cooled Lycoming R-680-9 radial engines, each delivering 295 hp (220 kW).
