The Dornier Do 27 is a German single-engine STOL utility aircraft that was designed and manufactured by Dornier GmbH (later DASA Dornier and Fairchild-Dornier). It was notable for being the first mass-produced aircraft in Germany following the end of the Second World War.
The Do 27’s precursor, the Do 25, was developed by Dornier at the firm’s facilities in Spain in order to satisfy a Spanish military requirement that called for a light utility aircraft with short takeoff and landing (STOL) performance.
Do 27B-5 model is the conversions of 27B-3s to 27A-4 standard.
