Developed from Diamond DA50

The prototype, designated as the DA52, first flew on 3 April 2012 after six months of development.[5][7] In June 2014 it was announced the production aircraft would be designated the DA62.[8][9]

Design and development

The DA62 development team is headed by Diamond managing director Manfred Zipper. It is based upon the fuselage of the single-engine Diamond DA50, but with two Austro AE300 Diesel engines burning Jet A fuel. Company CEO Christian Dries indicated that the engines may be replaced with turboprops.[4][7]

In flying the prototype from Diamond's Wiener Neustadt plant to the 2012 AERO Friedrichshafen aviation trade show, the aircraft achieved 16.6 mpg (14.2 litres/100 km) fuel efficiency, the result of improvements in cooling drag and aerodynamic drag made during its development.[10]

The company originally intended to have the aircraft available for sale in July 2013 and expected to offer fly-by-wire controls as an option by 2014, but development was delayed and those dates were not met.[5][6] The DA62 was European Aviation Safety Agency (EASA)-certified on 16 April 2015.[11][12] By September 2015, the company was preparing to deliver the first production DA62s to customers the following month and was manufacturing the first aircraft destined for the United States market — the tenth DA52/DA62 to be built and the third production aircraft — for an appearance at that year's National Business Aviation Association Convention in November.[2] American Federal Aviation Administration (FAA) certification was received on 23 February 2016[13][14] The FAA certification came ten months after EASA certification.[13] At the 2016 AERO Friedrichshafen show, Diamond's CEO Christian Dries reported that production would be increased to 60–62 aircraft per year to meet strong demand.[3]

The aircraft is available in two weight versions. The "European" version has five seats and a maximum takeoff weight (MTOW) of 1,999 kilograms (4,407 lb), the "US" version has seven seats and a MTOW of 2,300 kilograms (5,071 lb).[15][16] The lower MTOW of the "European" version is to allow operators to avoid higher weight-based air traffic control user charges.[2] The third row of seating and increased MTOW of the "US" version are available as factory options at extra cost.[15] At the 2016 AERO Friedrichshafen, Christian Dries said a special version with an additional baggage belly pod was under consideration for the air charter market.[3]

By April 2019 more than 120 DA62s had been delivered.[17] Aircraft are built in both Austria and Canada.

gollark: I don't even *eat* pizza.
gollark: This is NOT true. I have not in any way been sponsored by pizza companies. There have been no advertising agreements whatsoever with any companies producing pizza or otherwise to have me subliminally advertise pizza, as my profile picture is not a pizza. Since it is not a pizza, this is obviously not pizza advertisement whatsoever. No monetary exchanges or otherwise have occurred with companies engaged in pizza production for any reason relating to my profile picture. You are clearly engaged in libel and attempting to discredit my non-pizza-advertising status. It is IN NO WAY subliminal pizza advertising because I DO NOT work for pizza companies in any form. It's not pizza. There were no deals, under-the-table or otherwise, with pizza companies. No pizza companies pay for any kind of subliminal advertising involving me. People make that mistake, but I am not working for pizza companies doing subliminal advertising; that is not in any way what I am doing. I am NOT being sponsored by ANY pizza companies to display subliminal pizza advertising OF ANY KIND. Pizza companies have NO AFFILIATION with me in ANY FORM.
gollark: Footballs use pentagons and hexagons, actually.
gollark: I have no affiliation with pizza companies.
gollark: I did not.
