DA40 Diamond Star

The DA40 Diamond Star, introduced by Diamond Aircraft Industries in 1996, quickly became a benchmark for modern light‑sport and training aircraft. Developed from the earlier DA20, the DA40 incorporated a composite airframe that offers superior strength-to-weight ratios, corrosion resistance, and aerodynamic efficiency. Powered originally by the Lycoming IO-360‑M1A engine, later models adopted the fuel‑efficient Continental CD‑135 diesel, enabling operations on widely available Jet‑A fuel and extending range to over 800 nautical miles. Its glider‑like wing design, equipped with a high‑lift laminar flow airfoil, provides gentle stall characteristics and a cruise speed of around 150 knots, making it popular among flight schools and private owners. Advanced avionics suites, such as Garmin G1000 or G3X Touch, furnish pilots with integrated GPS, synthetic vision, and real‑time engine monitoring, enhancing safety and situational awareness. Over 2,000 units have been delivered worldwide, cementing the DA40’s role in modernizing pilot training, reducing operating costs, and showcasing the benefits of composite construction in general aviation. Certified by EASA and FAA under CS‑23, the DA40 is praised for reliability and is used in many ab‑initio programs. Optional ballistic parachute and low stall speed further enhance its safety.
