The ICON A5 is an American amphibious light-sport aircraft being developed by ICON Aircraft.[4] A concept aircraft was first flown in 2008, and creation of the production tooling began in December 2012. The first production aircraft made its first flight on July 7, 2014, and made its public debut at EAA AirVenture Oshkosh on July 27, 2014.

Design

Cockpit layout designed to resemble an automobile dashboard

The A5 is a high-wing flying boat-type amphibious monoplane with a carbon fiber airframe and retractable undercarriage. It seats two people in an enclosed cockpit and is powered by a single 100 hp (75 kW) Rotax 912 iS engine driving a three-bladed pusher propeller. Dornier-style sponsons provide hydrodynamic stability, housing the retracted main landing gear, and act as a step for crew and passenger. The wings can be folded aft for ground transport and storage.[5] Equipment includes an angle of attack indicator, an unusual feature in general aviation aircraft. An airframe ballistic parachute is optional.[3]

Development

ICON A5 with its wings folded for transport

A prototype was constructed from 2007 to 2008, and made its first flight in July 2008. In January 2009, the company announced completion of the first phase (27 flights) of a three-phase testing program, including water handling. In February 2009, the prototype entered the second phase of testing to refine aerodynamic and handling qualities.[6] In 2011, an updated "spin-resistant" wing was flight tested, and finished in February 2012. The design meets FAR Part 23 type certified requirements by employing a cuffed wing with multiple proprietary airfoils which change along the wing's span.[7][8][9] Lotus Engineering USA replaced BMW DesignworksUSA the same year to develop an "automotive style" aircraft interior and assist with development of lightweight component manufacturing.[10]

In July 2012, the company applied for a Federal Aviation Administration LSA rule exemption to raise the weight of the A5 above the maximum weight for amphibian LSAs, citing that the required structure to make the aircraft spin resistant necessitated a gross weight of 1,680 lb (762 kg). In May 2013 the FAA requested more details on the procedures used by Icon to test the spin resistance of the aircraft at the higher weight. The FAA also requested a signed statement from the company indicating that the aircraft meets the spin resistance criteria specified for light aircraft type certification in FAR 23.221 (a)(2). In July 2013 the FAA granted the weight increase.[11][12][13][14]

Production delivery dates have been adjusted from initial estimates. In June 2011, the company announced that it had procured an additional US$25 million investment, which was "needed to allow the company to complete engineering development work and enter production - possibly as early as next year [2012]."[15] By August 2011, the company stated that it had sold positions for 694 A5s, up from 400 initially sold at AirVenture 2009.[16] A promotion in conjunction with EAA Young Eagles raised more than US$28,000 for the youth flight program.[17][18]

On August 6, 2012, Icon announced that Cirrus Aircraft would produce composite airframe components for the A5 at its Grand Forks, North Dakota facility. The airframe parts will be shipped to Icon's Tehachapi, California plant for final assembly. In August 2012 the first production aircraft was anticipated for delivery in mid-2013 against 850 customer orders that the company says it was holding at that point.[19]

In December 2012, production of the tooling master molds began, with horizontal tail fin masters being delivered to Cirrus Aircraft that month. Wing skin masters were delivered in February 2013.[20]

On June 20, 2013, the company announced that it had organized production funding of over US$60 million, with final funds being provided by a Chinese investor.[13]

By July 30, 2013, the estimated production price had risen to US$189,000, from the company's initial estimated price established in 2008 of US$139,000.[3][14][21]

On October 2, 2013, the construction of production tooling was announced, which "will lead up to the assembly of the first pre-production aircraft to be completed in mid-2014."[22]

On July 27, 2014, the first production A5 was unveiled at EAA AirVenture Oshkosh. This aircraft was constructed between January and June 2014 at company headquarters in Tehachapi, California, and first flew on July 7. Icon stated that two additional aircraft would be constructed to "verify performance and complete FAA approval". The company plans to begin customer delivery in May 2015.[23][24]

Awards

In the 2009 IDEA/BusinessWeek Design Awards, ICON was awarded Gold in the Transportation Design category. The competition included all cars, motorcycles, watercraft, and every other motor vehicle designed in 2008.[25] ICON was also awarded a 2009 Gold Spark Design Award and a Design Distinction in ID Magazine's Annual Design Review.[26][27][28]
