Airframe & Avionics
All-carbon fiber composite airframe, fitted with retractable hydraulic tricycle landing gear and MT 3-blade constant-speed composite propeller.
Standard: Garmin G1000 NXi glass cockpit + GFC700 3-axis autopilot, equipped with ESP electronic stability protection and yaw damper.
Optional: TKS anti-icing system, cabin air conditioning, oxygen system, TCAS traffic collision avoidance system.
Core Competitive Advantages
Superior Fuel Efficiency & Global Fuel Availability
Runs on widely accessible Jet-A1 aviation kerosene instead of expensive, scarce AVGAS gasoline. Jet fuel is 30%–50% cheaper, eliminating fuel supply troubles at remote airports.
The high-efficiency turbo-diesel achieves the lowest hourly fuel consumption among all 5-seat piston aircraft in its class, delivering decisive fuel cost advantages over Cessna and Cirrus on long-distance flights.
Carbon Fiber Airframe: Safe, Durable & Low Maintenance
Corrosion-resistant with no aluminum oxidation or rivet fatigue issues, well-suited for coastal and humid operating environments and featuring an extended structural overhaul cycle.
High structural strength delivers excellent turbulence resistance. Its streamlined aerodynamic design reduces cabin noise far below traditional metal single-engine aircraft.
Resistant to minor ground scratches and bumps, greatly cutting sheet metal repair expenses.
Spacious & Comfortable Cabin
Boasting the widest cabin (1.29 m) in its class with 5 independent seats, it offers generous legroom and headroom for rear passengers, suitable for family travel and 4-passenger business trips.
The panoramic bubble canopy provides exceptional visibility. Optional leather upholstery, air conditioning and noise reduction systems effectively relieve long-flight fatigue. The model has won multiple international aviation design awards.
Digital Engine & Advanced Avionics: Higher Safety, Lower Pilot Workload
The dual-redundancy FADEC CD-300 engine automatically adjusts fuel mixture and turbo settings with single-lever control, eliminating manual mixture tuning and greatly reducing human error risks.
The full Garmin digital avionics suite supports instrument approaches, auto-route flight, terrain avoidance and real-time weather data. Standard flight protection prevents stall and spin for safer night and adverse-weather operations.
Long Range & High Payload for Versatile Applications
Even fully loaded with 5 passengers, the aircraft retains impressive range for private flights, pilot training, cross-region business trips, aerial inspection and general aviation missions. Retractable landing gear reduces drag to boost speed and lower fuel consumption.
Long Service Life & Strong Resale Value
Engine TBO: 2,000 flight hours or 12 years; Propeller TBO: 2,400 flight hours, longer than conventional air-cooled gasoline engines.
Diamond's global service network covers 90 countries. Backed by local authorized production and maintenance support in China, the DA50 maintains top-tier resale value among 5-seat single-engine GA aircraft.

- Carbon airframe requires no routine structural overhaul; professional repair is only needed after severe impact.
Maintenance Limitations & Hidden Cost Tips
- Maintenance must be undertaken by official Diamond authorized service centers; regular GA repair shops cannot service FADEC engines or composite structures, leading to limited service accessibility in remote areas.
- Core avionics and OEM spare parts are mostly imported with long lead times, causing downtime costs during part waiting.
- Retractable landing gear requires regular hydraulic fluid replacement and lubrication, adding one routine maintenance item compared to fixed-gear models.
Total Cost Summary (100 Flight Hours Annually)
Total Annual Ownership & Flight Cost: $39,200 – $53,200
