The Honda HA-420 HondaJet is the first general aviation aircraft developed by the Honda Aircraft Company.

Development[edit]

Honda began to study small sized business jets in the late 1980s, using engines from other manufacturers. The Honda MH02 was fabricated and assembled at Mississippi State University's Raspet Flight Research Laboratory in the late 1980s and early 1990s. The MH02 was a prototype using carbon fiber/epoxy composite materials.[3] Flight testing on the MH02 continued through 1996, after which the aircraft was shipped to Japan.

The prototype HondaJet made its maiden flight in December 2003. It debuted to the public at the EAA AirVenture air show in Oshkosh, Wisconsin, in July 2005. On July 25, 2006, Honda returned to Oshkosh to announce it would commercialize the HondaJet. Honda established the Honda Aircraft Company to seek both type and production certification of the HondaJet. Production is to take place in the United States. The company began taking customer orders in the fall of 2006. The price was about US$3.65 million. At that time the company expected to build 70 jets per year.

In August 2006 Honda and Piper Aircraft announced a partnership to market the HondaJet.[4]

In May 2010 major assembly of a type-conforming airframe started. Components included the composite fuselage, metal wings, empennage, landing gear and engine pylons mounted above the wings. Work was then in progress to integrate major systems, including electrical, hydraulic and environmental controls. The first conforming engine was to be delivered in the third quarter of 2010 and be installed on the aircraft. Honda Aircraft planned to begin static testing of a conforming airframe in May 2010.[5]

The maiden flight of the prototype aircraft was scheduled for November 2010. Because of delays in some components, the flight actually took place on 21 December.[6][7] FAA certification and delivery were repeatedly delayed,[8] including a one-year delay caused by the engines' susceptibility to ice damage.[9]

With the engine having achieved certification, the aircraft's certification is targeted to be in the first quarter of 2015.[10][11] First flight of the production model occurred on 27 June 2014[12][13] and the plane was flown and shown at Oshkosh Airshow soon after.[14][15]

An over-the-wing engine configuration was also used on the VFW-Fokker 614, a 44-seat German airliner, in the early 1970s. The VFW-614 was designed for eliminating ingestion problems and weight whereas the HondaJet’s innovative, over-the-wing engine mount configuration was designed for achieving lower wave drag at a high Mach number.[16] Retrieved June 5, 2014.

Honda began developing its own small turbofan engine, the HF118, in 1999. This led to the HF120, developed with GE Aviation under the GE-Honda partnership. The HF120 was test-flown on a Cessna Citation CJ1.[17] The engine features a single fan, a two-stage compressor and a two-stage turbine. The GE Honda HF120 received FAA type certification on December 13, 2013.[18]

Honda claims that the combination of lightweight materials, aerodynamics and efficient engines gives the HondaJet up to 20% better fuel efficiency than similar aircraft.[19]

The aircraft is equipped with a touchscreen 3-display Garmin G3000[6] glass cockpit system (i.e. most of the cockpit readouts are presented on flat-panel displays).

Fujino received the 2014 ICAS award for the design.[20]

In 2014, the plane was awarded 'Best of What's New' title by Popular Science magazine.

Production[edit]

The aircraft will be made at Piedmont Triad International Airport, Greensboro, North Carolina, USA. Construction of the factory began in 2007 and was completed in late 2011.[6][21] In July 2011 members of the media were invited to tour the facility, which was still under construction. At that time company representatives announced that certification was expected, and production of the airplane would begin late in 2012.[22]

In 2008 the Honda executives predicted that they would sell 70 planes per year.[23] In July 2011 they indicated their plan to produce (and therefore sell) 70 to 100 planes per year.[24] At the time of the first flight of the first production unit, company President and CEO Michimasa Fujino predicted that the first year's production would be 50 units, the next few years would see 90 units per year, with long-term production stabilizing at 80 units per year.[13]

On October 29, 2012 Honda announced that the HondaJet was entering production.[25] The first production HondaJet debuted at the 2014 EAA Airventure Airshow, with first deliveries soon after.[26][27] HondaJet had more than 100 confirmed orders in 2014.[28]

Legal actions[edit]

HondaJet is the only aircraft which has been removed from the open-source FlightGear simulator. In June 2014 Honda lawyers issued a takedown request in which they claimed that the use of the HondaJet model in the simulator infringes upon Honda's trademarks.[29]
