Diamond DA42 specs

Composite four-seat twin (the Twin Star) with two fuel-efficient Jet-A diesel engines, a Garmin glass cockpit, retractable gear, and a long-legged ~165 kt cruise on remarkably low fuel burn.

Cost to own a Diamond DA42

A twin, so two engines and two reserves — but the diesels sip Jet-A, which keeps the fuel bill closer to a high-performance single. Co-ownership is the usual way to make a modern twin pencil out, spreading the gearbox/engine reserves and insurance across a group.

What's different about the Diamond DA42

  • A composite four-seat twin with two Jet-A diesels and single-lever FADEC control — the redundancy of a second engine with fuel burn closer to a high-performance single.
  • Suits a group that specifically wants twin capability — IFR, night, over-water or mountain flying — in a modern glass-panel airframe, and is willing to share the higher fixed costs.
  • The honest trade-off is twin economics: two engines, two reserves (including gearbox overhauls), and twin insurance — exactly why the DA42 is so often co-owned rather than flown solo.

About the Diamond DA42

The Diamond DA42 Twin Star is the four-seat composite twin that reintroduced fuel-efficient diesel power to general aviation. Two Jet-A turbodiesels with single-lever FADEC control, a Garmin glass panel, retractable gear, and the same bonded composite airframe and bubble canopy as its DA40 sibling give it modern systems, a strong safety record, and a long-legged cruise in the 160s — all on a total fuel burn that embarrasses most avgas twins.

For a partnership, the DA42 is the affordable way into a modern twin. A second engine brings redundancy that owners value for IFR, night, and over-water or mountainous flying, and the diesels keep the Jet-A bill closer to a high-performance single than a legacy piston twin. The trade-off is two engines, two reserves, and twin insurance — exactly the fixed costs a group of partners is built to share, so everyone gets twin capability and a new-feeling glass cockpit for a sensible monthly number.

Diamond DA42 — frequently asked questions

Quick answers for buyers and prospective co-owners.

What is the Diamond DA42 Twin Star?

It is a composite four-seat twin powered by two fuel-efficient Jet-A diesel engines with single-lever FADEC control, a Garmin glass cockpit, and retractable gear. It is known for cruising in the 160s on remarkably low total fuel burn for a twin, and for its modern airframe and strong safety record.

How much does it cost to own a Diamond DA42?

It is a twin, so you carry two engines, two reserves, and a higher insurance bill — but the diesels sip Jet-A, which keeps the fuel cost closer to a high-performance single than a typical avgas twin. Most owners co-own a DA42 in a partnership to spread the engine/gearbox reserves and fixed costs.

Why choose a diesel twin over a piston single?

The DA42 gives you the redundancy of a second engine plus the economy of Jet-A diesels and a modern glass panel. It suits a group that specifically wants twin capability for training, travel over water or terrain, or all-weather IFR — and is willing to share the higher fixed costs that come with two engines.
