TheHeinkel HD 24 was atrainingseaplane developed inGermany in the late 1920s. It was a conventional single-baybiplane with equal-span,staggered wings. Thefuselage was braced to both the upper and lower wings with a number of struts on its sides, in addition to the normalcabane struts. The pilot and instructor sat in tandem, opencockpits, and theundercarriage consisted of twin pontoons, although this could be readily exchanged for wheels or skis.

Heinkel entered two HD 24s (alongside two HD.5) in the GermanSeeflugwettbewerb seaplane competition in 1926.[1] One of the HD.24 was the third placed[2] - only three aircraft completed the course and completed all the tests in the 11-day competition- leading to orders by theDVS (for 23 aircraft) and theSwedish Navy. The latter aircraft were to be built in Sweden bySvenska Aero based on two pattern aircraft provided by Heinkel. Before the Swedish examples could be delivered, theSwedish Air Force had assumed responsibility for Swedish naval aviation, and so took delivery of the six domestically produced machines, designating themSk 4.

One HD 24 was exported to China,[3] and another was bought by German explorerGunther Plüschow who named itTsingtau and took it on an expedition in 1927–28 toPatagonia andTierra del Fuego. The journey was recorded in his book and documentary filmSilberkondor über Feuerland. A full size replica of the Tsingtau D1313 is being assembled for static display as of April 17, 2009, inPuerto Madero,Buenos Aires,Argentina. It is located at about 500 of Alicia Moreau de Justo Avenue. This replica was located in the Aeroclub of Ushuaia, Province of Tierra del Fuego, Argentine; during a visit to the aeroclub on 5 November 2022 it was reported to have been scrapped. A new replica is being built for in El Calafate, Province of Santa Cruz, Argentine. It will be locate in the Glaciarium.
