variants with their own articles=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 principal difference between the types was that while the HD.14 had an entirely wooden structure, the HD.28's structure was almost entirely of metal. 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.

Some 300 examples were built under licence in Poland by Samolot and CWL, to equip the Polish Air Force and aeroclubs. A small number of aircraft were completed as locally-developed air ambulances similar in concept to the French HD-14S.
