Extra EA-400

The Extra EA -400 is a single-engine business jet travel and the German company Extra Aircraft is based at the airfield Schwarze Heide. It represents the forerunner of the turboprop version Extra 500 dar. Currently there are 29 machines in use by the manufacturer. The production was, however, set in favor of the Extra 500.

Generally

Extra 400 is a single-engine travel and business aircraft, which is designed as a high-wing aircraft. The tail is formed in T-shape. It has a hydraulic retractable landing gear of Gomolzig and a pressurized cabin with room for up to 6 travelers (including pilot ). The body is made of composite materials. The shelf life is 25 years, respectively 20000 h Produced was the extra 400 from the extra aircraft production and distribution GmbH, based at the airfield Schwarze Heide.

Development

The development of composite materials consisting of machine with a pressurized cabin and cockpit glass started in 1992 and was announced by February 1993. It was carried out in collaboration with the University of Delft. The first flight took place on 23 April 1996. This first prototype was used until 1997. The second prototype (D - EGBU ) first flew in April 1998, but crashed on 21 August 1998 during his extradition flight from. The FAA approval was granted on 15 April 1998.

Drive

The extra 400 is powered by a liquid-cooled 6 -cylinder boxer engine Teledyne Continental TSIOL 550 -C with 261 kW (350 hp). The constant- speed propeller is a MT-Propeller MTV-14-D/195-30a with 4 leaves and 1.95 m in diameter. Alternatively, could also be a three - door version will be delivered. The tank holds 680 liters. According to the manufacturer it was in the development of an agreement with the motor supplier Continental to supply a boost engine with 375 hp. This promise was not honored by Continental and so the extra 400 is considered underpowered. Only the transition to a turboprop Rolls- Royce with the extra 500 could deliver 450hp adequate performance.
