Diamond DA-42OPV OE-FSD

The Diamond DA42 Twin Star is a four seat, twin engine, propeller-driven airplane manufactured by Diamond Aircraft Industries. Its airframe is molded largely of composite materials.

Developing nation: Germany.
Manufacturer/designer: Diamond Aircraft Industries.
Production Lines:
  Wiener Neustadt, Austria and a large manufacturing facility in London, Ontario, Canada.
Type aircraft: Light twin-engined utility and trainer aircraft.
First flight: 9 December 2002.

The Diamond DA-42 Twin Star is an all new four place carbon fibre construction light twin powered by jet fuel burning turbo diesel engines.

Austria’s Diamond Aircraft unveiled the DA-42 at the May 2002 Berlin Airshow. The new aircraft flew on December 9 2002, leading to European JAA certification in late 2003 and US FAA certification and first deliveries in mid 2004.

The Twin Star’s design objectives include high speed cruise at very low throttle settings and good low speed handling. It is loosely modelled on Diamond’s DA-40 Diamond Star single engine four place (see separate entry), and features an all composite airframe with a high aspect ratio wing with winglets.
