Aircraft   |   Claudius Dornier «SEASTAR»

The SEASTAR is an amphibious aircraft, designed by the company Claudius Dornier SEASTAR. The company was founded by Claudius Dornier, son of the famous aviation pioneer Claude Dornier. The SEASTAR clearly shows its Dornier origins, resembling the Dornier Wal flying boat of the 1920 and the Do 18 of the 1930. The SEASTAR program started in 1982, the first proof of concept aircraft had its maiden flight on August 17th 1984. About 100 hours of flight testing and extensive water handling trials confirmed the concept and it was decided to start work on an all-composite airframe – fuselage and wing made of glass- and carbonfibre composites with the wing connected to fuselage by metal cabane struts. The company moved to Oberfaffenhofen airfield, close to Munich in Southern Germany and the first flight of the pre-series SEASTAR CD2 took place on April 24th 1987 with test pilot Alfred Lauf at the controls. Seaworthiness trials in the Baltic, off Kiel-Holtenau were conducted during October 1987. One year later, in October 1988 a second pre-production aircraft joined the certification flight test program. The design of the aircraft makes the SEASTAR suitable for a wide variety of missions, e.g. inter-island passenger and freight transport, feeder services from water bases to airports, maritime patrol and law enforcement, air ambulance.

The SEASTAR received its type certification by the German Luftfahrt Bundesamt on October 10th, 1990 and by the US Federal Aviation Authority (FAA) on June 10, 1991.

Up to now the SEASTAR never entered production. After some ups and downs, Miami, Florida based Dornier Seaplane GmbH announced the delivery of the first, modified production aircraft to be in 2018.
