The D-JET is a composite, five-seat, single-engine jet aircraft produced by Diamond Aircraft Industries. The aircraft is undergoing flight testing. The final cost is advertised as US$1.89 million, in March 2009 dollars.
Sales and marketing
Diamond has targeted the aircraft at the owner-pilot market, seeing it as more practical for single-pilot operations than the Eclipse 500 and the Cessna Citation Mustang. By limiting the altitude to 25,000 feet, it will be safer if pressurization fails. Diamond intends the D-JET to have a lower operating cost than other very light jets.
On November 9, 2006, at the AOPA Expo in Palm Springs, California, USA, Diamond announced that Airline Transport Professionals (ATP) placed the first fleet order of 20 Diamond D-JETs. ATP will provide factory-approved training to D-JET purchasers beginning in 2008. Toronto-based Chartright Air Group ordered 10 D-JET aircraft with expected delivery beginning 2010.
In February, 2008 Diamond announced that the aircraft will be built in a new plant in London, Ontario, Canada. This announcement came after the Government of Canada announced it was giving the company a “Cdn$19.6 million strategic, repayable investment” and the Government of Ontario announced that it had given the company Cdn$11 million. Diamond claims that research and development costs for the D-JET have been Cdn$95.2 million and that the plant to build the aircraft will cost an additional $100 million.
In October 2008 Canadian charter operator SwiftJet announced that they had ordered five D-Jets with options for ten more. SwiftJet's intention is to offer air taxi service "anywhere and anytime to destinations around the world." SwiftJet currently operates one Dassault Falcon 20 in the charter role.
The D-JET was initially to be powered by one Williams FJ-33-4A-15 turbofan engine. That 1,564 lbf (6.96 kN) thrust engine was found in early 2008 to produce insufficient bleed air for cabin pressurization and other services. As a result a decision was made to switch to the Williams FJ-33-4A-19 turbofan engine, which produces 1,900 lbf (8.5 kN) of thrust instead.
The switch in engines delayed the certification schedule and moved the projected first customer deliveries of the aircraft into the spring of 2009.
Diamond is also developing a military trainer variant of the D-JET that will likely feature Martin-Baker lightweight ejection seats and is intended to sell for under US$3M.
Flight testing and certification
The first flight of the D-JET was made on April 18, 2006 from the London International Airport (ICAO: CYXU) in Ontario, Canada the homebase of Diamond’s North American division. The flight was piloted by test pilot Gérard Guillaumaud and lasted 1:06 hours. The aircraft's public debut was at Oshkosh in July 2006. After completion of flight testing, Diamond expects full certification in the middle of 2009 with deliveries starting at the same time.
On Friday, July 20, 2007 Diamond Aircraft announced the roll out of its second D-JET, serial number 002. Serial number 002 is the first D-JET intended to conform to the expected production configuration in its structural layout and aerodynamic design. D-JET prototype serial number 002 first flew on Friday 14 September 2007. It was joined by D-JET Serial Number 003, which first flew on April 15, 2008.
