Dornier Do 27
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. However, the Do 25 was not selected for production by Spain. Despite this, the aircraft was developed further to produce the Do 27, which was produced in quantity in both Spain and Germany. In addition to domestic sales, a large number of export customers, such as Portugal, emerged for the Do 27, and it had a lengthy service life with some examples still being used into the twenty-first century. The aircraft was appreciated for its relatively wide, comfortable cabin and excellent short-field performance. In terms of its configuration, the Do 27 was a classic high-wing, "tail-dragger" aircraft with fixed landing gear.
Shortly following the end of the Second World War, Germany's extensive aerospace industry was dismantled and largely dissolved due to the country having been forbidden to either possess or manufacture military aircraft. Despite this, in both East Germany and West Germany, as the nation had been divided into during the Cold War era, efforts to revive the nation's aerospace industry became widespread during the 1950s.
German aircraft manufacturer Dornier GmbH managed to retain its independence in the conflict's aftermath, and was keen to resume its aviation activities as soon as permissible. During January 1951, the company chose to establish a new technical office in Madrid, Spain, and began bidding for contracts from Spain's Ministry of Aviation; prior to this, Dornier had developed strong ties to Spain via the licensed production of the Messerschmitt Bf 109 fighter.
During 1951, a development contract was secured for a commuter aircraft that possessed short takeoff and landing (STOL) characteristics. Dornier opted to develop a new aircraft, designing a monoplane with a high-mounted wing fitted with oversized flaps, a wide wraparound windscreen, a fixed undercarriage and a relatively spacious cabin. This new aircraft was powered by a single ENMA Tigre G.V; capable of generating a maximum of 110 kW (150 hp), this engine proved to be too weak to achieve satisfactory performance. The first prototype of the Do 25 performed its maiden flight during July 1954.
Due to the Tigre's performance deficit, it was decided to equip the second prototype with an alternative powerplant; it used the American-sourced Continental O-470 engine instead. The second prototype would subsequently function as a demonstrator for an improved derivative of the aircraft, designated Do 27.
Ultimately, the Do 25 was not selected for production. Despite this setback, Dornier decided to continue refining its design to develop the Do 27, which was sized to seat between four and six personnel. On 27 June 1955, the original prototype performed its maiden flight in Spain. A total of 40 Do 27s were manufactured in Spain by Construcciones Aeronáuticas SA, designated CASA-127. However, the majority of production aircraft were constructed at Dornier's main base in Germany; the first German-built aircraft conducted its first flight on 17 October 1956. A total of 428 Do 27s would be produced in Germany.
A significant portion of the Do 27's production run were acquired by the German military. By the mid-1950s, West Germany had been permitted, and even encouraged, to reequip itself as tensions rose between East and West in the Cold War; due to its ability to operate from compact and unprepared airstrips, the Do 27 quickly garnered favour with military planners. Both the German Air Force and the German Army placed a combined order for 428 aircraft of the Do 27A and Do 27B variants, the latter being equipped with dual controls for use as a trainer aircraft.
