The SyberJet SJ30 is an American business jet built by SyberJet Aircraft. The SJ30 has been under development since the late 1980s and has been the subject of investment and partnership with a number of companies.

Development

An SJ30 prototype

Ed Swearingen announced a new design for a light twin business jet in October 1986, the SA-30 Fanjet.[1] The SA-30 was to be a 6 to 8 person aircraft powered by two Williams FJ44 turbofans and with a highly swept wing of relatively small area. It was planned to be more efficient than contemporary business jets, and to sell for $2 million.[2] In October 1988 an agreement was signed with Gulfstream Aerospace with the SA-30 to be manufactured and sold by Gulfstream as the Gulfstream Gulfjet. Gulfstream withdrew from the project in September 1989, causing Swearingen to get backing from the Jaffe Group of San Antonio, with the aircraft to be built in a factory next to Dover Air Force Base, Delaware. This resulted in the aircraft again being redesignated as the SJ-30 (later "SJ30-1"). The first SJ-30 flew on 13 February 1991, and was demonstrated at the 1991 Paris Air Show, but development ground to a halt when withdrawal of financial support from the state of Delaware.[3]

The SJ30 is in the "light" jet class, and has the fastest cruise speeds and longest range of any aircraft in that class.[4] The aircraft can seat up to six passengers plus one pilot. A unique feature of this aircraft is that it maintains a 'sea level cabin' (zero cabin altitude) up to 41,000 ft[5] (due to its 12 psi differential pressure) thereby reducing fatigue due to high cabin altitude on long journeys.

The program was rescued by Lockheed, who arranged a joint venture between Swearingen and Taiwanese investors as part of the offset agreement for Taiwan's purchase of the F-16 fighters. The Sino Swearingen Aircraft Corporation was set up, with the aircraft now to be built at Martinsburg, West Virginia.[3]

It was subsequently decided to modify the original design as the SJ30-2, with a 4 ft 4in (1.32 m) longer fuselage and wingspan increased by six foot (1.83 m).[6][7] This promised a significant increase in range.[8] The prototype was modified and flew in the new configuration on 8 November 1996, and with the intended FJ44-2a engines on 4 September 1997.[8] Amidst construction delays caused by funding issues, two "as-designed" pre-production aircraft (serial numbers 002, performing the aerodynamics/stability & control testing; and 003, performing systems testing) were built and the design entered certification testing. However, in April 2003, S/N 002 crashed during flight testing, causing further delays in the certification program. After a series of additional design changes, S/N 004, originally slated as the functionality & maintainability (F & M) test article, took over the testing role of S/N 002 (with S/N 005 taking on the F & M role), and after years of flight testing, the SJ30-2 was finally certified by the FAA in October 2005. The first customer delivery took place in early 2007.

Throughout the years the SJ30 program has been the first in many respects, and while small in size it has led the industry in firsts. Below are just several of the key industry and SJ30 program milestones:

The SJ30 program was the first aircraft program to successfully petition for and gain approval to certify as a Part 23 Commuter Category jet. In 1996 Sino Swearingen petitioned to certify as a Commuter Category aircraft arguing that it was as safe, or safer than the current Part 23 Commuter Category aircraft. At the time only the Fairchild Metro 23 and the Beechcraft 1900D had been certified under these rules. Approval of this request allowed the SJ30 program to exceed the 12,500 lbs takeoff weight limit of Part 23 and paved the way for other companies to follow the SJ30 lead.

The SJ30 program was the first to fly both the William’s FJ44-1 and FJ44-2A engine and was instrumental in developing the engines with Williams International. Subsequent incorporation of the engines at Cessna and Raytheon led to their CitationJet and Premier aircraft, respectively.

In keeping with Ed Swearingen’s vision of a better light jet, the SJ30 was the first aircraft designed around a 12 psi cabin for more comfort in the cabin. The 12 psi cabin results in a sea level cabin through 41,000 ft and less than a 1,800 ft cabin at its ceiling of 49,000 ft. The 12 psi cabin was first demonstrated in flight by company pilots on August 23, 2004.

As proof of its speed and range capability the SJ30 holds the following world’s records through the FAI/NAA:

In 2006, Fédération Aéronautique Internationale (FAI), the international umbrella organization of the National Aeronautic Association (NAA) awarded Sino Swearingen Aircraft Corporation’s SJ30 the FAI Honorary Group Diploma.

Sino Swearingen was acquired by investors from Dubai in 2008. The Dubai-based company will become the majority shareholder in Sino Swearingen, with the Taiwanese government and private investors taking minority stakes. The company name was changed to the Emivest Aerospace Corporation.

The order book for the $7.5 million aircraft was reported to be largely unaffected by the funding setbacks, with the tally reportedly exceeding 300 units including 159 from Action Aviation.

On October 26, 2010, Emivest filed for bankruptcy after being unable to find further funds to continue operations.[9]

The original SJ30-1 prototype was on display at the Lone Star Flight Museum in Galveston, Texas when it was flooded by Hurricane Ike.[10]

On April 7, 2011, a judge approved sale of Emivest assets to MT LLC of Utah, an ownership group affiliated with Metalcraft Technologies, Inc. of Cedar City, Utah, a parts supplier for the SJ30. According to a news article, Emivest vice president Mark Fairchild stated that according to his understanding, MT planned to maintain Emivest as a jet manufacturer, though he didn't know any details.[11]

As of June 15, 2011, Metalcraft Technologies, the Cedar City, Utah-based company that purchased Emivest out of bankruptcy, MT LC, announced that the new company name would be SyberJet Aircraft.[12] Metalcraft also owns the SJ30 type certificate.[13][14]

During and in support of the NBAA show SyberJet signs contract with Honeywell International for the development and purchase of its APEX (now Epic 2.0) avionics platform to be branded as SyberVision for the SJ30. In addition, SyberJet's factory Part 145 service center is appointed as a Williams International service station.

Honeywell was chosen for several reasons, but the ability to get to market the quickest as well as their more attractive financial model pushed the decision in their favor.

In June 2013 SyberJet announces a family of companies under the MSC Aerospace brand. MSC Aerospace is a family of integrated and synergistic companies with aerospace related operations. SyberJet Aircraft is the manufacturer of the world’s fastest light jet, the SJ30. SyberJet assemblies major assemblies, installs components, and systems, complete final assembly and production ground and flight tests in Cedar City, Utah as well as offices that include executive, finance, procurement, completions, and sales/marketing offices. The Texas location provides engineering, flight test operations, and flight training, as well as the location for the central repair station for support of the SJ30 customer fleet. Cedar City also has a satellite repair station location to support the West Coast customer fleet. Metalcraft Technologies, Inc (MTI) is another one of the MSC Aerospace companies which supports the fabrication and assembly of detail aircraft parts and aero-structures for leading aircraft manufacturers. In fact, MTI produced approximately 70% of the sheet metal parts and assembled the aft fuselage on the SJ30 since 1997. Other customers include Lockheed-Martin, Boeing, Gulfstream, Middle River, Piper Aircraft, and Cessna Aircraft.CBI Associates is the third member of the MSC Aerospace family and is real estate development and management arm of MSC.

SyberJet announces final assembly location during press ceremonies in Cedar City, Utah. The Utah Governor’s Office of Economic Development Board of Directors and elected officials from Iron County and Cedar City have approved financial incentives for MSC Aerospace (MSC) and its subsidiaries SyberJet Aircraft (SJA) and Metalcraft Technologies (MTI) totaling almost $45 million. MTI and SJA will use these incentives to expand their manufacturing facilities in Cedar City, Utah in support of the production of the SJ30 business jet.
