The Dornier Do 27 was a German single-engine STOL utility aircraft, manufactured by Dornier GmbH (later DASA Dornier, Fairchild-Dornier). Configuration was a classic high-wing, "tail-dragger" aircraft with fixed landing gear.

History

The Do 27 was developed from the Do 25, an aircraft originally designed to a Spanish military requirement for a light utility aircraft.

The Do 27 seated four to six and the original prototype first flew in Spain on 27 June 1955. Most production aircraft were built in Germany, the first taking flight on 17 October 1956. The remainder (50) were manufactured in Spain by Construcciones Aeronauticas (CASA) as the CASA-127.

The German Luftwaffe (Air Force) and Heer (Army) ordered a total of 428 of the Do 27A and Do 27B (with dual controls).

A later version with the same basic specifications but equipped with wider track landing gear was known as the Do 27Q-5. The aircraft was offered as a twin-float seaplane, the Do 27S-1, and with a larger engine (254 kW/340 hp Lycoming GSO-480-B1B6) and a three-blade propeller as the Do 27H-2.

In addition to the military operators in Germany and Spain, a few were manufactured for other military and civilian operators.

The Do 27 was notable for being the first mass-produced aircraft in Germany after World War II. It was appreciated for its relatively wide, comfortable cabin and excellent short-field performance.
