The Diamond DA42 (initially certified in 2004/2005) is the first production general aviation aircraft to make widespread use of modern turbo-diesel engines and full FADEC engine management in a light twin-engine platform. Built with a carbon-composite airframe for strength and low weight, the DA42 pairs fuel-efficient Austro AE300 engines with advanced glass-cockpit avionics (typically Garmin G1000/G1000 NXi and GFC autopilot), making it both economical to operate and capable of extended IFR and cross-country missions. 
With a service ceiling around 18,000 ft, cruise speeds generally in the 170–180 KTAS range, and over 1,200 nautical miles of range, it delivers performance that rivals many larger singles while ret aining the redundancy and safety benefits of twin-engine flight.
The original diesel-powered twin in the DA42 lineup, the NG introduced Jet-A efficiency and FADEC simplicity to the light-twin market. Equipped with early Austro AE300 engines, it delivered strong fuel economy, smooth engine management, and solid single-engine characteristics. Its composite airframe and modern avionics made it especially attractive to flight schools and owner-pilots seeking a technologically advanced, cost-conscious twin.
The refined evolution of the platform, the DA42-VI incorporated aerodynamic improvements, higher maximum takeoff weight, and updated propellers to enhance performance and payload. Powered by improved Austro AE300 engines, it offered better climb, slightly higher cruise efficiency, and greater mission flexibility. These refinements positioned the VI as a capable cross-country aircraft for owner-operators while retaining its strong training pedigree.
Developed for operators preferring avgas powerplants, the DA42 L360 replaced diesels with Lycoming IO-360 engines for more conventional maintenance and fuel sourcing. While sacrificing some fuel efficiency, it retained the DA42’s composite structure, stable handling, and advanced avionics suite. This variant appealed to markets where Jet-A availability or diesel support was limited, offering familiarity in a modern twin airframe.
Designed as a mission-focused platform, the DA42 MPP adapted the standard airframe for surveillance, mapping, and special-mission operations. Featuring reinforced structures, optional extended endurance, and provisions for sensors and payloads, it emphasized loiter time and reliability over speed. Its quiet operation, efficiency, and twin-engine redundancy made it well-suited for government, research, and commercial aerial operations worldwide.
