Diamond's Firsts

During the 1950s and 1960s Cessna's marketing department followed the lead of Detroit automakers and came up with many unique marketing terms in an effort to differentiate its product line from their competitions'.

    Visionary leadership, coupled with a keen passion for flying, means innovation is ingrained in everything we do. Expanding the bounds of what was thought possible before, Diamond is proud of our long list of aviation firsts.

Suitable Triple R Diamond Aircraft

Diamond DA-20

The Diamond DA20 is a two-seat tricycle gear general aviation aircraft designed for flight training. In addition to its role as a civil and military training aircraft, it is also used for personal flying by pilot-owners.

Development The first DA20 was the Rotax 912 powered A1 Katana produced in Canada in 1994. It was the first Diamond aircraft available for sale in North America. Production of the Continental IO-240-B3B powered C1 Evolution and Eclipse models began in 1998, also in Canada. Production of the A1 Katana is complete but the DA20-C1 is still being constructed in 2010.
The DA20-A1 and C1 are both certified under CAR 523[4] in Canada and under FAR 23 in the USA. The DA20 is certified in the utility category, and it is permissible to intentionally spin it with flaps in the full up position.[5] In 2004, Diamond received Chinese certification for the DA20. Both models also hold JAA certification.
Although the DA20 is available with instrumentation and avionics suitable for flight under instrument flight rules (IFR), its plastic airframe lacks lightning protection and thus does not qualify for IFR certification.

Design The DA20 features control sticks (as opposed to yokes), composite construction, a canopy, low-mounted wings, a single fuel tank, a T-tail, and a castering nosewheel. All models have composite airframes constructed of glass- and carbon-fiber reinforced plastic.[2] The nose wheel of the DA20 is not linked to the rudder pedals and turns while taxiing are made with differential braking, with rudder steering becoming more effective as airspeed increases.
The DA20 is equipped with a bubble canopy. Small windows on either side of the canopy can be opened on the ground and in flight to provide cockpit ventilation. This canopy design, however, lets in an above-average amount of sunlight into the cockpit, increasing the cockpit's initial temperature. The DA20's seats are reclined and are not adjustable, instead the rudder pedals are adjustable fore and aft to accommodate pilots of different height. The fixed seats provide better occupant crash protection. The seats in the C1 variant have a less obtuse angle, but, like the A1, are not adjustable. Both models are available with cloth or leather seat coverings.
The DA-20 possesses a higher glide ratio than many of its competitors. The glide ratio of the DA20-C1 is 11:1 and the DA20-A1 is 14:1.
In November 2008 the company announced that it would be offering an Aspen Avionics glass cockpit primary flight display as an option on the DA20. Diamond indicated the Aspen PFD was easy to incorporate into the existing instrument panel design because it mounts in a standard round instrument hole. In October 2009 the company introduced the Garmin G500 glass cockpit as an option.

Diamond DA-40

The Diamond DA40 Diamond Star is an Austrian four-seat, single engine, light aircraft constructed from composite materials. Built in both Austria and Canada, it was developed as a four-seat version of the earlier DA20 by Diamond Aircraft Industries.

Design and development Based on the success of the earlier DA20 two-seat aircraft, the company designed a four-seat variant, the DA40. The DA40 is a four-seat low-wing cantilever monoplane made from composite materials. It has a fixed tricycle landing gear and a T-tail. The Rotax 914-powered prototype DA40-V1, registered OE-VPC, first flew on the 5 November 1997 and was followed by a second prototype DA40-V2 (registered OE-VPE) which was powered by a Continental IO-240. In 1998 a third prototype DA40-V3 flew powered by a Lycoming IO-360 engine. Four more test aircraft were produced followed by the first production aircraft in 2000. JAR23 certification of the IO-360 production variant was obtained in October 2000. In 2002 the production of the Lycoming-engined variant was moved to Canada and the Austrian factory concentrated on diesel-engined variants.

The DA40 has officially appeared in only three versions, the DA 40, DA 40D and DA 40F, as documented on its type certificates. The various model names that the aircraft has been sold under are marketing names and are not officially recognized by the authorities that have certified the aircraft.

Operational History The DA40 has accumulated a very low accident record, particularly with regard to stall and spin accidents. Its overall and fatal accident rates are one eighth that of the general aviation fleet and include no stall-related accidents. The level of safe operation is attributed to its high aspect ratio wing, low wing loading and benign flight characteristics. The aircraft can be trimmed full nose up, engine set to idle and it will descend at 600-1200 feet per minute at 48 kn (89 km/h) hands-off, a lower rate of descent than the competitive Cirrus SR22 can achieve with its airframe ballistic parachute deployed.

In a 2011 analysis by Aviation Consumer magazine, the DA40 was shown to have a fatal accident rate of 0.35/100,000 hours, the lowest in US general aviation and considerably better than the Cirrus SR20 and SR22 with a combined fatal accident rate of 1.6/100,000 hours, despite its full aircraft parachute system. By comparison, the Cessna 172 has a fatal accident rate of 0.45/100,000 hours.

Diamond DA-42 TwinStar

Development The DA42 Twin Star was certified in Europe in 2004 and in the United States in 2005.
The airplane is made of carbon composite material. It is equipped with a Garmin G1000 glass cockpit.
The DA42 Twin Star was the first diesel-powered fixed-wing aircraft to make a non-stop crossing of the North Atlantic, in 12.5 hours, with an average fuel consumption of 5.74 gallons per hour (2.87 gallons per hour per engine).
In June 2010 a DA42 powered by Austro AE300 engines became the first aircraft to be publicly flown on algae-derived jet fuel.
By March 2012 the DA42 had become the major income driver at Diamond Aircraft. Company CEO Christian Dries indicated that the market focus of the company had been changed by the recession of 2008—2010 and that the company now derives two-thirds of its revenue from military and government contracts, primarily for manned and unmanned (Aeronautics Defense Dominator) surveillance aircraft.
Also in March 2012 Diamond aircraft announced they were developing a fly-by-wire version of the DA42, with the aim of reducing the accident rate in light aircraft. The system is expected to eventually include flight envelope protection, turbulence righting and autoland capabilities. The system will also include damage-tolerant by-pass capabilities, allowing flight with jammed or missing controls.

Powerplants The DA42NG "New Generation" is powered by Diamond's 3rd Generation Austro Turbo Diesel Engine, the Lycoming IO-360 engine is also available as an option. The 168 hp (125 kW) Austro diesel replaces the Thielert Centurion 1.7 and 2.0 engines. It is known for its excellent efficiency, it burns only 3.2 gallons per hour in loiter or 8 gallons per hour at maximum continuous power (92%). It is also available with optional "on top" exhaust mufflers that reduce noise levels to below 59 decibels at 500 feet.
Thielert Aircraft Engines ended its production of the 1.7 L. Centurion engines (designated as TAE 125-01 Centurion 1.7) in favour of a new 2.0 L. (TAE 125-02-99) engine.[13] Diamond began installing this new 2.0 L. engine in early 2007. Although engine displacement increased, it was de-rated to produce the same horsepower (135) and torque (302 ft·lbf.) as the 1.7 L. engine.
In late 2007, Diamond aircraft announced it would begin building and installing its own aerodiesels, through a subsidiary, Austro Engine GmbH, and with other partners that included Mercedes Benz Technologies. The use of Thielert engines on the DA42 came into question due to Thielert filing for insolvency in April 2008.
Due to the insolvency of Thielert and the decisions of the insolvency administrator, including cancelling warranty support and the prorating of time-between-overhaul for the Thielert engines that power the DA42, Diamond announced in July 2008 that production of the DA42 was suspended. At the time production was suspended the DA42 was reported to have 80 percent of the piston twin market.
In March 2009 Diamond achieved EASA certification for the Austro Engine AE 300 and returned the DA42 to production as the DA42 NG. The new engine produces 20% more power, while giving better fuel economy than the Thielert engines and results in a higher gross weight and increased performance. The first Austro-powered DA42 was delivered to a customer in Sweden in April 2009, with the first US customer aircraft expected in mid-2010. The Austro-powered DA42 NG received FAA certification on 9 April 2010.
