A low-wing tandem two-seat monoplane, the PT-1 was the first Piper aircraft to have a low-wing. It had a fabric covering over an all-metal fuselage frame and wooden spar wings and tail unit. The PT-1 had a retractable tailwheel landing gear and was powered by a 130 hp (97 kW) Franklin 6AC-2980D engine. No further aircraft were built." ] ,
