History of the Dornier Do27: 1951 Dornier started investigations on the construction of a light liason-transport and survey aircraft after an announcement of the Spanish Ministry of Transport. C. Dornier jr. was the leader of this group of engineers. The developed prototyp was named Do25. Two prototypes were finally built in Sevilla. 25.6.54 The maidenflight of the first prototyp Do25-P1 was performed at Sevilla/Spain. The aircraft was equipped with a 150 hp Enmasa Tigre G IV B engine. The testprogram was performed until end of 1954 by the spanish airforce. After this time nothing else is known about the fate of this prototype. The second prototype the Do27-P2 was completed in 1954. The powerplant was an Continental O-470-J engine (230 hp). Maidenflight took place on 27th of June 1955. The aircraft was registered as EC-AKY. After Germany had received back it´s national air-sovereignity, this prototyp was brought to Germany and received the registration D-EBUC. The fate of this second prototype is as well not known. 1955-56 The main construction of the Do27 was completed in Spain. As powerplant the Lycoming GO480-B1A6 was chosen. The difference to the Do27-P2 was mainly the construction of the wing ( 2 pieces), enlarged vertical fin, different doors and rudders and the increased max. take-off weight. Feb. 1956 The German Armed Forces placed an order of 469 Do27 for the three units Airforce, Navy and Army. In 1957 the order was reduced to 428 aircraft. The Swiss Airforce ordered 7 Do27. 17.10.56 Maidenflight of the first Do27 (# 102) at Oberpfaffenhofen. Registration was D-EKER. # 101 was a static test airframe which was used for chrash-tests only. The first Do27 taken in charge by the Armed Forces was # 103 (Model B1). Civil Registration D-ENAT. Taken on charge as PA+101. Both aircraft, D-EKER and PA+101 were destroyed in 1959 and 1957. 1957 The Do27 is displayed at the Aero-Salon at Paris/Le Bourget. 05.11.57 The first civil Model of the Do27 leaves the productionline at Oberpfaffenhofen. # 2001, Registration D-ENTE. The aircraft was delivered to Prof Grizmek and operated mostly in the plaines of the Serengeti/Tanzania. 1965 Dornier ceased the production of the Do27. 626 aircraft had been built, including the prototypes and 50 CASA C127. 1976 The last (627th) Do27-B3 (#2200) was built to match an order against 2 Do27 which was placed by Rheingau Airservice/Rüdesheim. At this time #2200 (D-EGAO) was built, #2045 (D-EGAP) was overhauled. 1980 The last annual check on a military Do27 was performed by the Armed Forces. This was the end of the Do27 in the military units. In the seventies the German Armed Forces reduced the amount of Do27 step by step. They were sold to private owners, donated to flying clubs or other Armed Forces in foreign countries.
Estimated number of Do27 flying worldwide: approx. 100 Following Do27 are registered in the BRD Germany:
