Diamond DA50 RG for sale: what to check before you buy
Published November 13, 2026.
The Diamond DA50 RG is a five-seat composite single with retractable gear and a 300 hp diesel engine that burns jet fuel. It has only been delivered since the early 2020s, so the used market is small and young. Below is what the official type certificate data sheet says, what today's listings show, and what to check before an offer.
What the data sheet says
On the type certificate the aircraft is the DA 50 C; DA50 RG is the sales name. The figures below come from the UK Civil Aviation Authority's data sheet for the type.1
| DA 50 C (DA50 RG) | Official data sheet |
|---|---|
| Engine | Continental Centurion 3.0 (sold as CD-300), 221 kW takeoff, 200 kW continuous |
| Fuel | Jet A-1; 185.4 litres usable in two tanks |
| Propeller | MT MTV-12-D/210-56, three blades, 2.10 m |
| Max. takeoff and landing mass | 1,999 kg (4,407 lb) |
| Seats | 1 pilot and 4 passengers |
| Max. operating altitude | 20,000 ft |
| Never-exceed speed | 189 knots |
| Eligible serials | 50.002, 50.003, 50.006, and 50.C.A.A.007 on |
According to the official data sheet, the aircraft is approved for VFR day and night and for IFR. Flight into known or forecast icing is approved only with the ice protection system of design change OÄM 50-011 installed. The Garmin G1000 software and the engine firmware must match the versions in Diamond's mandatory service bulletins.1
What today's listings show
On November 13, 2026, the PlaneFox aggregator, which collects listings from European and American portals and brokers, showed 18 DA50 listings. One is a co-ownership share; the other 17 are whole aircraft, several of them new or demonstrators.2
| PlaneFox, 11/13/2026 | DA50 RG |
|---|---|
| Whole aircraft listed | 17 |
| 2021 and 2022 aircraft priced in euros | 4, from €850,000 to €945,000 |
| Hours on those four | 377 to 545 |
| 2025 aircraft with 5 hours | €1,210,000 |
| New 2026 aircraft, United States | US$1,225,280 |
One 2024 listing gives a serial number in a format that does not exist for the DA50, which is why the serial is the first thing to check. Asking price is not selling price.
What to check on any DA50 RG
- The serial number. Valid serials are 50.002, 50.003, 50.006 and 50.C.A.A.007 onwards.1 A listing with another format needs to be corrected before anything else. The routine for checking serial, registration and owner is in this post.
- Ice protection. Many listings mention TKS or "anti-ice". The data sheet approves flight into known icing only with design change OÄM 50-011.1 Ask for the record of that change, not just a description of the equipment.
- Engine time and limits. Ask for the engine and gearbox hours, the time between overhaul or replacement in force for that engine, and the calendar limits. The CD-300 is a diesel engine with its own maintenance logic, as on the DA40 TDI.
- Software status. Ask which G1000 software and which engine firmware are installed, and whether they match Diamond's current service bulletins.1
- Warranty. This part is our reading. Most DA50s are only a few years old, so part of the factory warranty may remain. Ask what is left and whether it transfers to a new owner.
- Airworthiness directives. Check the directives for the airframe, engine and propeller, and compliance in the records.3
The DA50 RG we have for sale
- Diamond DA50 RG: 60 hours on the airframe, engine and propeller, still flying, Garmin G1000 NXi, CD-300 engine, €1,155,000.
With 60 hours it has far fewer hours than the 2021 and 2022 aircraft for sale, and its price is closer to that of the 2025 aircraft. The year, serial number, the equipment actually installed and the warranty status are confirmed with the seller on request. If you are comparing with a twin, see DA42 or DA62.
