The Diamond DA42 Twin Star is a four seat, twin engine, propeller-driven airplane manufactured by Diamond Aircraft Industries.

The DA42 Twin Star was certified in Europe in 2004 and in the United States in 2005.

The DA42 is unusual in that it is powered by two Thielert Centurion 1.7 diesel engines. In the United States, Jet-A or Jet-A1 fuel (or premix) is used. Fuel consumption is about half that of avgas powered light twins of comparable gross weight.

The airplane is made of carbon composite material and equipped with a Garmin G1000 glass cockpit. A proof-of-concept version powered by two 180 hp Lycoming IO-360 engines also exists.

The DA42 Twin Star was the first diesel-powered aircraft to make a non-stop crossing of the North Atlantic, in 28 hours, with an average fuel consumption of 11.2 gallons per hour.
