The Loening PA-1 (Pursuit-Air cooled) was an American fighter aircraft prototype built by Loening Aeronautical Engineering.


The PA-1 was the first air-cooled, radial engine-powered aircraft. It was a single-seat biplane with N-struts, an all-wood fuselage, and wings with fabric coverings. The USAAS ordered two prototypes. The first one first flew in March 1922. It did not deliver the desired speed, so the construction of the second prototype was cancelled.
