The Hanriot HD.28 was a military trainer aircraft developed in France in the 1920s as a modernised version of the HD.14 for export markets.

The landing gear was also of more conventional design, with only one wheel on each main unit, plus small anti-noseover skids.

The two tandem cockpits of the HD.14 were replaced by a single, long cockpit in which both pilot and instructor sat.

The aircraft designated as Hanriot H-28 was in fact a Polish-built (at Samolot and CWL), slightly modified version of the wooden-construction Hanriot HD.14.
