The PT-19 is a primary trainer aircraft used during World War II, primarily by the United States Army Air Forces. It was designed by North American Aviation and features a low-wing monoplane structure with a conventional tail. The aircraft is powered by a Continental O-170 engine, which provides reliable performance for novice pilots. The PT-19 was notable for its tandem seating arrangement, allowing an instructor and student to sit in line. Its design emphasized ease of handling and visibility, making it an effective tool for training pilots before they transitioned to more advanced military aircraft.
