The Dornier Do 28A was a twin-engine STOL utility aircraft, manufactured by Dornier Flugzeugbau GmbH. It served with Spanish Ejercito del Aire during the "Ifni Incident" on West Sahara.
The Do 28 was developed from the single-engine Do 27 at the end of the 1950s. The design shared the high-wing cantilever layout and the lift augmentation devices of the Do 27, together with the rear fuselage which seated six passengers.
The most defining feature of the new design was the unusual incorporation of two Lycoming engines, as well as the two main landing gear shock struts of the faired main landing gear attached to short pylons on either side of the forward fuselage.
The internal space of the Do 28A/B was the same as the Do 27 and the company was given financial assistance from the German government to develop a larger STOL transport to carry up to 13 passengers. The type was designated the Do 28D and later named Skyservant.
The Dornier Do 28A was the designation of production aircraft with 250 hp (190 kW) Lycoming O-540-A1A engines, 60 built. First flown on 20 March 1960 at Oberpfaffenhofen. One aircraft was used for the personal transport of the German Defense Minister, Franz Josef Strauss.

This virtual model represent the Ejercito del Aire Dornier Do 28A # 407+7.
This aircraft is yet preserved at Ejercito del Aire Museum of Spain.
Special thanks to Christian Maas for his excellent tool Hex-editor XVI32 and Chuck Dome by his MDL file viewer. Without their tools, I might not have been able to assign new textures to the original model.
I have included new textures, moving parts and damage profile for use with CFS1, with ficcional armament of windows machine guns, rockets and bombs.
