Development[edit | edit source]
Seeing the success of the Navy's NY-1 modification of a PT-1 airframe, the USAAC came to the conclusion that a radial engine was indeed ideal for a trainer. It was reliable and offered a good power-to-weight ratio. Therefore one PT-1 airframe was completed as XPT-2 with a 220 hp (164 kW) Wright J-5 Whirlwind radial engine.
The XPT-3 was almost identical with the XPT-2 except for the tail, revised wing panels and different shape. One hundred and thirty production PT-3 aircraft were ordered in September 1927, with one being completed as the XO-17. These were followed by one hundred and twenty PT-3A aircraft with minor changes. The XPT-3 became the XPT-5 when fitted with the Curtiss Challenger R-600 two-row 6-cylinder radial engine, but was soon converted to PT-3 standard.
The PT-3 aircraft were superseded by the Boeing PT-13 Stearman starting in 1937, but a number were still operational with the Spartan Flying School in Tulsa Oklahoma into the middle of World War II.
