History

Despite its name, the aircraft type had nothing to do with the Auster J/1B Aiglet, it being an aerobatic development of the Auster J/5 Autocar.

The Aiglet Trainer was based on the J/5 fuselage with new wings and stressed for aerobatics. The prototype first flew on 2 June 1951.

Most Aiglet Trainers were bought by private pilots and flying clubs, but 15 went to the Pakistan Air Force, 14 to the Iran Civil Aviation Club and two to the Lebanese Air Force.[1]
