About the Diamond DA40 NG
Overview
The Diamond DA40 NG is the diesel-powered version of Diamond Aircraft’s four-seat DA40 Diamond Star, a composite low-wing single produced from 2010 to the present. “NG” (New Generation) marks the switch to the 168-horsepower Austro AE300 turbocharged common-rail diesel, which burns Jet-A through a single-lever FADEC power control. It keeps the DA40’s glider-derived wing, bubble canopy, and T-tail, and is certified under EASA type certificate EASA.IM.A.022 (JAR-23 normal category).
Choose the DA40 NG when low fuel cost, worldwide Jet-A availability, and a benign safety record matter more than outright speed. It sits at the premium end of the four-seat training and personal-travel market – costlier to buy than a Cessna 172S Skyhawk or Piper Archer but far cheaper to feed, and a natural cross-shop against the AvGas Cirrus SR20 and its own gasoline Diamond DA40 XLT sibling for buyers weighing diesel against AvGas. Flight schools outside North America favor it where Jet-A is the only practical fuel; owners step up to the twin-engine Diamond DA42 Twin Star when they want two engines or more cabin.
Key Features for GA Buyers
- Jet-A economy. The Austro AE300 burns about 5.1 gph of Jet-A at economy cruise, a fraction of a comparable AvGas single’s fuel bill.
- Single-lever FADEC. Full-authority digital engine control gives one-lever power management with automatic mixture and propeller control, cutting pilot workload.
- Glass flight deck. Typically equipped with the Garmin G1000 NXi suite and GFC 700 autopilot.
- Composite safety record. The fail-safe composite airframe, energy-absorbing seats, and docile stall give the DA40 one of the lowest fatal-accident rates in general aviation.
Trade-offs
- Payload vs fuel. With the 39-gallon long-range tank full, cabin payload for four adults plus baggage gets tight.
- Modest climb. The roughly 690 fpm sea-level climb trails turbocharged or higher-powered competitors.
- Diesel reserve burden. The AE300’s overhaul reserve and gearbox service add a maintenance line the simpler Lycoming XLT avoids – the trade for the fuel savings.
- Cabin access. The step-over entry under the canopy is awkward for less-mobile passengers.
