It was Diamond's first twin engine design, as well as the first new European twin-engine aircraft in its category to be developed in over 25 years. In 2004, the DA42 became the first diesel-powered fixed-wing aircraft to perform a non-stop crossing of the North Atlantic. The Diamond DA42 Twin Star is a twin-engined low-wing cantilever monoplane, commonly used as a general aviation aircraft for touring and training purposes. It is equipped with a retractable tricycle landing gear arrangement and uses a T-tail. The DA42 incorporates a combination of advanced features within the company's first twin-engine design. The airframe is composed of composite materials, making extensive use of carbon fiber reinforced polymers throughout its structure; this construction provides the aircraft with a suitable passive safety level to conform with the established European Aviation Safety Agency (EASA) Part 21 rules, as well as relatively efficient aerodynamics and essentially unlimited airframe life.[3] The carbon-fiber main wing spars possesses exceptional crashworthiness. The DA42 typically accommodates four people in two rows of seating. All of the seats have been designed for crashworthiness and are complete with automotive-style three-point seat belts; while the seats themselves are fixed in position, the position of the rudder-pedals is adjustable. The front pair of seats are accessed via a front-hinged canopy while a top-hinged door located on the left side provides access to the rear seats. The pilots are housed under a sizable canopy which provides generous external visibility, save for the use of a large fixed sunscreen. Additionally, separate baggage compartments, which are accessible via external hatches, are contained within internal space in the aircraft's nose.
