DA42
The definition of perfection

The DA42-VI, our latest DA42 version, is  easy to fly and burns fuel like a single, but with the added safety of a second engine. The impressive cross-country performance will please you! No wonder it’s the bestselling piston twin, by far.

The DA42-VI is wonderful. She does everything you promised. TAS 175-180 with a fuel burn of 13 gph total at altitude. Climbs like a rocket through the ice layer, 1350 fpm and still 1100-1200 at altitude. Radar is great. Use it a lot. Data link is great. Weather and sending emails and SMS at altitude. I don't think there is any other piston twin that comes close price/performance-wise. For those of us who don't want to spend what it takes to fly a turboprop, the DA42-VI is the perfect airplane. Just flew to Oxford England this afternoon. The flight deck was busy. All the tools came into play. What a dream machine!

Diamond Factory Engine and Airframe Program

The first hourly cost maintenance program for piston aircraft

We are thrilled to be the first piston aircraft and engine manufacturers to offer a program that jet owners have enjoyed for years. Now with PistonPower™ our owners and operators can benefit from cost predictability and substantial peace of mind.

"I chose the Piston Power program for my 2019 DA40 NG because it enabled me to build a fixed maintenance expense into my shared use business model.  My plane is shared with three other pilots, who pay me a monthly rate for airplane access up to 100 hours/year each.  The fixed maintenance cost is built into this rate.  The other pilots know I have no incentive to "skimp" on maintenance, delay it due to cash flow considerations, or surprise them with some kind of 'maintenance assessment'.  Everything is built-in.  As a first-time owner of a TAA, I also found value in Piston Power's expertise in overseeing the entire maintenance process, from spinner to rudder.  I appreciate having their experience working for me.  Their collaboration with Diamond Aircraft to tailor the program specifically for the DA40 NG and it's Austro 300 Jet-A engine gives me added confidence that my plane will be well maintained for safety, reliability, and performance.  The four of us can focus on flying, enjoying the airplane and the personal opportunities it provides us." ~ Paul Koch ~

Flying Magazine’s Editors’ Choice Award 2009

“... the company launched parallel programs to: a) re-engine the DA-42 with conventional gasoline-powered Lycomings of much higher power; and b) to develop its own Austro diesel engine — a significant improvement over the original in performance, efficiency and maintainability. The seemingly impossible was completed in a remarkable 18 months.” ~ Statement Flying Magazine  ~
