Our high-performance single is a twin

The DA42 is easy to fly and burns fuel like a single, but with the added safety of a second engine. Impressive cross-country performance pleases private pilots and business owners alike, while the low operating costs make it an ideal advanced trainer. No wonder it’s the best selling piston twin, by far.

DA42-VI At A Glance

  • 4 seats, convenient access
  • Panoramic canopy
  • Luxurious leather interior
  • G1000NXi with 3-axis GFC700 & Yaw Damper
  • Twin 170hp Jet fuel AE300 Engines
  • Superb Single Engine Performance
  • High Fuel Efficiency
  • TKS Ice Protection (FIKI)

Imagine this: It’s getting dark. You’re in the mountains, crossing big water or densely populated terrain. You’re picking up ice and your intended destination just closed. At times like this, the security of the second engine, incredible endurance and single engine performance, a FIKI certified ice protection system, superior situational awareness courtesy of the supreme Garmin G1000NXi glass flightdeck, and an autopilot with razor sharp precision and standard Electronic Stability & Protection (Garmin ESP™), are – quite simply – life insurance.

The performance, stability, handling characteristics and ease of operation of the DA42 make it an easy transition from single to twin. Superb performance with a single engine service ceiling of 18,000’ offers a margin of safety that single engine aircraft simply do not have. Especially when flying in inclement weather, over inhospitable terrain, over water and at night, nothing beats the safety of continued flight in case of engine failure. That is why Diamond’s high performance piston is a twin.

The DA42’s unique combination of performance and utility will impress pilots looking to go direct, even in unfriendly weather. Flight schools training the next generation of professional pilots benefit from the DA42’s superior recruitment appeal, while enjoying low total life cycle costs that make the DA42 thebest value, as well as the most capable aircraft, on any flight training line.

The DA42 offers exceptional visibility thanks to its panoramic wrap around canopy and generous rear windows. Comfortable access for all on board is assured through the forward swinging canopy and large rear door that provides access to the folding rear seats and fuselage baggage area. Additional baggage is stowed in two generous nose compartments that are sized for golfbags and offer maximum flexibility in loading for any mission. Comfort is assured by adjustable front seatbacks and lumbar support. Luxury features abound throughout, including premium leather interiors in several styles and colors, all LED interior lighting, optional electric air conditioning and more.

The sleek all carbon composite airframe incorporates advanced aerodynamics with the latest in passive safety technology for high performance, great efficiency and superior occupant protection. The composite airframe is durable, easily maintained and will keep looking great for many years to come.


The turbocharged Austro AE300 jet fuel piston engines perfectly match the DA42’s aerodynamically efficient airframe, burning less than 17 gph, combined, at a high speed cruise of 190 ktas, and less than 11 gph overall in a typical flight training environment.

Control is jet-engine simple, with each engine / propeller combination controlled by a single power lever and power settings displayed in % power. Simplified power control means that you can focus on more important things and that is not just more convenient, but safer too.

The 3 blade MT hydraulic constant speed propellers feature advanced blade geometry for efficient performance, smoothness and low noise. They are automatically controlled by each engine’s digital engine control through conventional hydraulic governors. Feathering is as simple as flipping a single switch.

The DA42’s AE300 170 hp jet fuel piston engines have been in service in Diamond’s DA40 and DA42 since 2009. With over 1,200 engines in service and a total fleet time of well over 600,000 hrs as of November 2015, the AE300 has proven itself to be smooth, reliable and efficient.

Austro Engines and MT Propellers are supported by North American based factory support and parts centers and a network of Authorized Service Centers.
