The Fairchild PT-23 was a key component of the U.S. Army Air Forces' primary flight training program during World War II. It was developed as an evolution of the PT-19, replacing the inline Ranger engine with a more powerful and widely available radial engine — the Continental R-670. This modification offered greater durability and simplified engine maintenance for training environments.
Introduced in 1942, the PT-23 retained the same low-wing monoplane configuration and open tandem cockpits of the PT-19, giving student pilots a solid foundation in basic flying skills before progressing to more complex aircraft. The aircraft's forgiving handling characteristics, combined with its stable flight profile and clear visibility, made it ideal for early training phases.
Although the PT-23 was not as numerous as its inline-engine sibling, it still saw extensive use and was built under license by several manufacturers, including Howard Aircraft and Aeronca. Today, surviving examples are appreciated in airshows and museums as reminders of the thousands of airmen who began their flight careers in these sturdy trainers.
