TheDiamond DA40 Diamond Staris anAustrianfour-seat, single-engine,light aircraftconstructed fromcomposite materials.Built in both Austria and Canada, it was developed as a four-seat version of the earlierDA20byDiamond Aircraft Industries.

By the end of December 2020, 2,200 DA40s had been delivered, including 500 NG models.[1]

Development

[edit]

Based on the success of the earlierDV20/DA20two-seat aircraft, the company designed a four-seat variant, the DA40 Diamond Star. TheRotax 914-powered prototype DA40-V1, registered OE-VPC, first flew on 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 ondiesel-enginedvariants. The first flight of the Diesel DA40D was made on 28 November 2002.

In late 2006, the XL and FP models replaced the DA40-180. The FP replaced the fixed pitch propeller version of the 180 and the XL replaced theconstant speed propellerversion. The major difference between the new models and the 180 is the higher maximum cruise speeds. The DA40-XL is approximately four knots faster than the preceding DA40-180/G1000 with the two-bladeHartzellpropeller and the "Speed Gear" option. The XL's speed increase is mostly due to the Powerflow exhaust system.[clarification needed]

In the last half of 2007 the company updated the DA40 line by introducing the XLS and CS versions and eliminated the FP model. The XLS is the deluxe version, with the integration of some options into the standard offering including a Powerflow tuned exhaust, WAAS-capable G1000, GDL69 datalink, and TAS traffic alert system. The CS is the budget version, with fewer standard features.[2]

Both CS and XLS versions of the DA40 use the Lycoming IO-360-M1A fuel injected engine. The major difference is the choice of propeller, with the CS using a Hartzell two-blade aluminum constant speed prop and the XLS using an MT composite three-blade unit.[3][4]

Capacity is available for up to 1,000 aircraft a year to be produced with certification by theEuropean Aviation Safety Agencyin 2008.[5][6]

Past DA40 models were available with either traditional mechanical instruments or an optionalGarmin G1000glass cockpitsuite. Current[when?]production DA40s are built only with the Garmin G1000 as standard equipment. In April 2008, Diamond introduced the optional availability ofGarminSynthetic Vision Technology on the DA40 XLS.[7]

In October 2021, Diamond Aircraft announced an all-electrictraining variant, the eDA40, with initial flights scheduled for the second quarter of 2022 and EASA/FAA Part 23 certification expected in 2023.[8]It should fly for 90 minutes, with a fast charge for 20 minutes turnarounds and operating costs 40% lower than piston aircraft.[8]

Design

[edit]

The DA40 is a four-seat low-wing cantilevermonoplanemade from composite materials. It has a fixedtricycle landing gearand aT-tail.

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.[3][4]

The DA40 was initially marketed as the DA40-180, powered by a fuel injectedTextron Lycoming IO-360 M1Aengine.[3][4]

The DA40-XL has a constant speed propeller and is powered by a 180 hp (130 kW)Lycoming IO-360-M1Afuel injected engine. It has a maximum cruise speed of 147 kn (272 km/h; 169 mph), burning 9.2 gallons ofAvgasper hour. Its maximumtakeoffweight is 2,535 lb (1,150 kg).[9]

The DA40-F (marketed as the "FP" ) has a fixed pitch propeller, a 180 hp (130 kW)Lycoming O-360-A4Mengine, which has acarburetorrather than fuel injection and a more basic interior, but is otherwise similar to the XL.[3][4]

The DA40-TDI uses aThielert"Centurion" 135 hp (101 kW)diesel engineand burns diesel orjet fuel.It has a constant speed propeller andFADEC(single lever) engine control. The Diesel DA40D is not certified in theUS.[3][4][10]

Efforts to increase the DA40's cruising speed centered on the propeller and wheel spats. The wheel fairing streamlining was improved, a three-blade scimitar-type constant speed propeller was incorporated and the Powerflow exhaust system from the XL was retained. The canopy contour was also revised, with the sides being more vertical before curving into the roof, which provides more shoulder and head room.

Boarding the DA40 is via the leading edge of the wing, an unusual feature among low-wing aircraft. The aircraft's nosewheel is free-castoring and directional control whiletaxiingis by mainwheel differential braking.[11]

DA40s are produced at Diamond's aircraft factories inWiener Neustadt,Austriaand inLondon, Ontario,Canada.A joint venture has also been set up in China withShandong Bin Ao Aircraft Industriesfor production of the DA40 TDI (Diesel) inShandong Province.[12]

Operational history

[edit]

The DA40 has accumulated a very low accident record, particularly with regard tostallandspinaccidents. 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 highaspect ratiowing, lowwing loadingand benign flight characteristics. The aircraft can be trimmed full nose up, engine set to idle and it will descend at 600–1,200 feet per minute (180–370 m/min) at 48 kn (55 mph; 89 km/h) hands-off, a lower rate of descent than the competitorCirrus SR22can achieve with its airframeballistic parachutedeployed.[13]

In a 2011 analysis byAviation Consumermagazine, the DA40 was shown to have had a fatal accident rate of 0.35/100,000 hours, the lowest in US general aviation and considerably better than the market leadingCirrus SR20andSR22,which that year had a combined fatal accident rate of 1.6/100,000, despite its full aircraft parachute system. By comparison, theCessna 172had a fatal accident rate of 0.45/100,000 hours.[14]

A Chinese flying school has used its CD-135 for 13 hours per day on average.[15]
