In the early 1980s, Claudius Dornier Jr. a multi-purpose amphibious aircraft that can be used from grass runways as well as from water, snow and ice surfaces without special equipment. The first flight of the test model VT-01 (also known as PT-01) took place in August 1984. In order to save time and money during flight tests, this machine was equipped with the metal wings of the Do 28 . Claudius Dornier was the eldest son of Claude Dornier and, even after retiring as Chairman of the Board of Directors of Dornier-Werke at the end of 1981, he felt strongly committed to his father's legacy - building seaplanes. First, the project was developed within the Dornier works on his behalf. In 1985 - after the takeover of the Dornier works by Daimler-Benz - he founded his own company, Claudius Dornier Seastar GmbH & Co KG, which continued the project.

The type certification was issued in October 1990 by the Federal Aviation Office and in June 1991 by the US DoT (FAA) . At this point there were two firm buy orders, five options and 72 orders. However, the Federal Ministry of Economics stopped the necessary funding so that the program was put on hold in Germany by Conrado Dornier, son of Claudius Dornier, who had taken it over to his company Dornier Composite Aircraft GmbH & Co KG in 1986 after the death of his father. In order to secure the technological basis that had been created, Conrado Dornier founded Dornier Seastar GmbH & Co. KG in 1991 , which was merged into Dornier Seawings AG in 2001. With the aim of realizing the Seastar program, the only remaining Seastar will be kept airworthy to this day. In the meantime, this pre-production aircraft has received a one-off license, which also enables IFR flight operations . Occasionally it can be visited on sightseeing flights. At the end of 2008 it became known that the newly founded Dornier Seaplane GmbH , based in Miami, is planning to manufacture a modernized version. Saint-Jean-sur-Richelieu in the Canadian province of Québec was announced as the production location in May 2010 , the final assembly will take place in Oberpfaffenhofen and later the aircraft will also be produced in China.

In 2013, two Chinese state-owned companies from Wuxi and the Dornier family merged to form a joint venture under the name Dornier Seawings GmbH. The first flight was supposed to take place in 2019 and the first deliveries were planned two years later. On March 28, 2020, the first flight of the D-IDSW with the serial number 1003 took place at Oberpfaffenhofen airfield.

Technical specifications

Proven principles of the earlier Dornier flying boats and modern technology are combined in the Seastar:

  • The Seastar is a semi-self-supporting screen high-wing , whose structure is braced. The two Pratt & Whitney engines are set up in tandem with a push and pull propeller each . This unusual arrangement ensures reliable flight behavior in all weather conditions and even if an engine fails, as there is no asymmetrical thrust in single-engine flight.
  • The cantilever tail unit corresponds to the standard design and includes a very high set tailplane in cross-configuration.
  • The retractable landing gear is located in the boat hull and in two fin stubs to which the aforementioned sponsons are attached. The single-tyred nose wheel is located in the bow of the fuselage, the single-tyred main landing gear legs in the stubs.

Possible uses

During development, Dornier, in line with tradition, placed great emphasis on the versatility of the pattern. The possible uses of a land plane are combined with those of a sea plane at the cost level of a conventional land plane. The manufacturer mentions the following possible uses:
