Aircraft overview

The Diamond DA50 RG is a five-seat, retractable-gear single produced by Diamond Aircraft in Austria. The DA50 program first flew in prototype form in 2007, while the production DA50 RG configuration was certified by EASA in 2020 and entered customer deliveries soon after. It occupies a distinct place in the market: a modern composite personal and business aircraft with a diesel piston engine, retractable landing gear and a larger cabin than Diamond’s four-seat DA40 family.

Performance & specifications

Typical published performance for the Diamond DA50 RG includes a maximum cruise speed of about 181 knots, a range of about 750 nautical miles and a service ceiling of 20,000 feet. Useful load is commonly quoted at up to about 1,230 lb, depending on equipment and configuration. Power comes from the Continental CD-300, a 300 hp, turbocharged, liquid-cooled diesel engine burning Jet-A fuel. The combination of FADEC engine management, long-range fuel availability and retractable gear makes the DA50 RG notably different from fixed-gear avgas singles in the same ownership discussion.

Cabin & avionics

The DA50 RG has seating for five, with a two-place front row, two rear seats and a fifth center rear seat. The composite fuselage gives the aircraft a wide cabin by single-engine piston standards, with large gullwing doors at the front and a separate rear door. Baggage capacity and cabin access are important inspection points for buyers who plan regular family or business trips. The typical avionics suite is Garmin G1000 NXi, usually paired with the Garmin GFC 700 autopilot. Many aircraft also feature synthetic vision, traffic, weather options, electronic engine monitoring, oxygen and TKS de-icing equipment, depending on specification.

Buying & value

On the used market, the Diamond DA50 RG is still a relatively young type, so condition often depends more on equipment choices, operating environment and maintenance history than age alone. Buyers should review CD-300 engine records, FADEC and software status, landing gear maintenance, de-icing system condition if fitted and any service bulletins or warranty work. Common value drivers include TKS, air conditioning, oxygen, premium interior trim and avionics options. Current PlaneFox listing data shows an average asking price of about EUR 907,000, with observed asking prices from EUR 689,000 to EUR 1,210,000. This positions the DA50 RG above many legacy piston singles, but below many new high-performance cabin-class alternatives.
