From 1945 to 1955, it was forbidden to Germany to develop or manufacture aircraft on their own. Do 27 was the first aircraft to go into mass production in the 1950s. The maiden flight of the Do 27 took place on October 17, 1956 at Oberpfaffenhofen, the just re-opened airport of Dornier. The Do 27 based on the Do 25 which was designed by "Oficinas Tecnicas Dornier" (OTEDO), Madrid, on behalf of the Spanish Ministry for Aviation. In contrast to its predecessor Do 25, Do 27 received improvements such as the more powerful 274-HP Lycoming power plant GO-480-B1A6, a new main landing gear, a two-part wing instead of a continuos spar, integral wing tank, and larger vertical stabilizer including the rudder. When the ban on aircraft construction in Germany was lifted in 1955, a contract of the Federal Armed Forces (Bundeswehr) allowed series production of the Do 27 liaison and utility aircraft. Between 1955 and 1964, more than 600 aircraft of this type were built, including 428 for the Bundeswehr in different versions (including aircraft with floats and turboprop engine).
With its excellent STOL characteristics, the versatile and rugged Do 27 was not only used in Germany, but in all parts of the world as liaison, observation, ambulance, rescue, training, business, surveying, agriculture and silviculture aircraft and for glider towing and aerial advertising.
