The Diamond DA50 is a five seat, single-engine, composite aircraft designed and built by Diamond Aircraft Industries. First shown in 2006, it made its maiden flight on 4 April 2007. The project has been proposed to be powered by several different engines, but was certified on 9 September 2020 with the Continental CD-300 diesel.
The DA50 Super Star prototype was unofficially first shown in December 2006 at a Diamond company Christmas party. [1] The aircraft was designed with the intention of fitting it with gasoline, turboprop or diesel engines up to 350 hp (261 kW). The initial design goal was that it would have one of the largest cabins of the new generation of general aviation airplanes. [2]
The avgas-powered version of the DA50 was intended to be equipped with a single FADEC-equipped Continental TSIO-550-J powerplant with twin turbo chargers producing 350 hp (261 kW). The plane's wingspan was reported as 38.3 ft (11.67 m), with overall fuselage length of 29 ft (8.84 m). The maximum takeoff weight was planned to be 3,527 lb (1,600 kg). The Diamond DA50 Super Star was intended to be pressurized and to offer a Ballistic Recovery Systems aircraft parachute system as an option. [2]
The DA50 made its first test flight on 4 April 2007 at the Wiener Neustadt East Airport, Austria. [3] The airplane made its public debut at the AERO Friedrichshafen show in Germany on 19 April 2007 and was first shown in North America at Airventure in July 2007. [4]
The DA50 project was put on hold in 2009 as the economy entered the Great Recession and Diamond turned all their attention to the Diamond D-Jet. [5]
On 19 January 2015 the prototype, now designated DA50-JP7 and powered by an Ivchenko-Progress Motor Sich AI-450S turboprop powerplant, was test-flown in Wiener Neustadt. In 2015 type certification was expected near the end of 2016. [6]
At the April 2017 AERO Friedrichshafen show, Diamond announced DA50 variants powered by diesel SMA Engines and other powerplants. These included the four-seat 230 hp (172 kW) DA50-IV, the five-seat 260 hp (194 kW) DA50-V and seven-seat 360 hp (268 kW) DA50-VII - also proposed to be powered by a 375 hp (280 kW) gasoline Lycoming engine or an Ivchenko-Progress Motor Sich AI-450S turboprop. The DA50-V model was displayed at that show. It had made its first flight in March 2017 and at that time certification was planned for 2018. [7]
By April 2019 no DA50 models had been produced beyond one single prototype. The company then announced a new version of the design with fully retractable landing gear and a Continental CD-300 diesel engine, [8] at the 2019 AERO Friedrichshafen show. [9] That retractable gear-equipped second prototype was first flown on 28 October 2019. At that time Diamond planned to announce its price and start accepting orders at the Aero Friedrichshafen show in April 2020, with European certification and introduction expected in the third quarter of 2020. [10]
Diamond Aircraft announced EASA certification of the DA50 RG (retractable gear) on 9 September 2020, with deliveries planned to start in the first quarter of 2021. [11] FAA certification and the aircraft's first U.S. sale occurred in July 2023. [12]
The five-seat DA50 RG airframe is constructed predominantly of composite material. It is powered by a single 300 hp (224 kW) Continental CD-300 diesel engine, with a fuel capacity of 50 U.S. gallons (190 L; 42 imp gal). [13]
The design features double-slotted flaps, retractable landing gear, a Garmin G1000 NXi flightdeck with autopilot and single lever power controls. [13] Optional equipment includes a removable right-hand control stick, an on-board oxygen system, electric-powered air conditioning, a TKS de-icing system and a Garmin GCU 476 input keypad. [9]
The aircraft cruises at 180 kn (333 km/h) and has a 750 nmi (1,389 km) range, with a fuel economy of 9 US gal (34 L) per hour. [13] It has a useful load of 1,232 lb (559 kg). [9]
In its first long flight, a factory demonstrator DA50 RG was flown from the factory in Austria to the China AirShow 2021 in Zhuhai, Guangdong. The flight involved 12 stops en route and took 45 flight hours over eight days, flying 7,033 nmi (13,025 km). [14]

The Cessna 172 Skyhawk is an American four-seat, single-engine, high wing, fixed-wing aircraft made by the Cessna Aircraft Company. First flown in 1955, more 172s have been built than any other aircraft. It was developed from the 1948 Cessna 170 but with tricycle landing gear rather than conventional landing gear. The Skyhawk name was originally used for a trim package, but was later applied to all standard-production 172 aircraft, while some upgraded versions were marketed as the Cutlass, Powermatic, and Hawk XP. The aircraft was also produced under license in France by Reims Aviation, which marketed upgraded versions as the Reims Rocket.
The Thielert Centurion is a series of diesel cycle aircraft engines for general aviation originally built by Thielert, which was bought by Aviation Industry Corporation of China's Tecnify Motors subsidiary and is currently marketed by Continental Motors. They are based on heavily modified Mercedes-Benz automotive engines.

The aircraft diesel engine or aero diesel is a diesel-powered aircraft engine. They were used in airships and tried in aircraft in the late 1920s and 1930s, but were never widely adopted until recently. Their main advantages are their excellent specific fuel consumption, the reduced flammability and somewhat higher density of their fuel, but these have been outweighed by a combination of inherent disadvantages compared to gasoline-fueled or turboprop engines. The ever-rising cost of avgas and doubts about its future availability have spurred a resurgence in aircraft diesel engine production in the early 2010s.
The Diamond DA42 Twin Star is a four seat, twin engine, propeller-driven airplane developed and manufactured in Austria and Canada by Diamond Aircraft Industries, an Austrian subsidiary of China-based Wanfeng Aviation. It was Diamond's first twin engine design, as well as the first new European twin-engine aircraft in its category to be developed in over 25 years. In 2004, the DA42 became the first diesel-powered fixed-wing aircraft to perform a non-stop crossing of the North Atlantic.
