The Consolidated Model 2 was a training airplane used by the United States Army Air Corps, under the designation PT-3 and the United States Navy under the designation NY-1.
Development
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.[1]
The XPT-3 was almost identical to the XPT-2 except for the tail, revised wing panels and different shape. 130 production PT-3 aircraft were ordered in September 1927,[1] with one being completed as the XO-17. These were followed by 120 PT-3A aircraft with minor changes. The XPT-3 became the XPT-5 when fitted with the Curtiss Challenger R-600 two-row six-cylinder radial engine, but was soon converted to PT-3 standard.[2]
The PT-3 aircraft were superseded by the Boeing PT-13 Stearman starting in 1937, but a number were still operational with the Spartan Flying School in Tulsa Oklahoma into the middle of World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.[1]

Surviving aircraft
- The last Consolidated PT-3 was amongst the aircraft lost in the San Diego Air & Space Museum 1978 fire.[5]
- An airworthy PT-3 replica belongs to the EAA Aviation Museum in Oshkosh, Wisconsin. It incorporates parts of a PT-1 that once flew with the 154th Observation Squadron of the Arkansas National Guard, was later owned by the University of Arkansas College of Engineering and was rebuilt as a PT-3 reproduction with a radial J-5 Engine.[6]
