SubSonex Update: FAA NKET Checklist Posted, SubSonex Gets New Gear and New Test Flight Video Footage is Available!

The three months since AirVenture Oshkosh 2014 has seen tremendous progress in the development and production of the SubSonex Personal Jet! SubSonex EAB Quick Build and SubSonex Ultra Quick Build kit production is well underway for our inaugural group of customers, and all of those customers have visited us here in Oshkosh since the first flight of JSX-2 to see more of the aircraft. The mutual excitement between Sonex personnel and this special group of customers is contagious as the project continues to develop!

FAA NKET Checklist Published
The FAA National Kit Evaluation Team (NKET) visited Sonex Aircraft once again in late August, this time with the task of auditing the SubSonex EAB Quick Build Kit for compliance with the "major portion" requirement of 14 CFR section 21.191(g) for experimental/amateur-built aircraft, commonly referred to as the "51 Percent Rule." The SubSonex checklist created during that visit was approved on September 15th and posted recently to the FAA's web site listing of audited kits. More information and links to the FAA NKET documents can be found on our Aircraft Certification web page.

SubSonex Gets New Landing Gear
Unsatisfied with the level of reliability and possible failure modes of JSX-2's original electric actuator landing gear system, the SubSonex development team began work immediately after AirVenture to convert the aircraft to a pneumatic landing gear system. The pneumatic actuators are simpler and more reliable with a longer service life, are available at lower cost, feature a simple and more reliable gear position indication system using hall effect sensors, and have a safer failure mode than the original electric gear -- loss of air pressure in the system causes the gear to deploy and lock due to gravity. A demonstration video of JSX-2's new air-driven landing gear system can be found on YouTube!

Another Round of Extensive Flight Tests Completed: New Video Posted!
SubSonex primary test pilot Bob Carlton was in-town again in late September during a perfect week of flying weather, allowing Bob and the SubSonex development team to conduct another round of very extensive flight testing with JSX-2. All aspects of performance were explored, as we continue to expand the SubSonex envelope. We're pleased to report that the aircraft performed flawlessly, and continues to exceed our expectations in it's performance and handling. A new video featuring excerpts from these flights has been posted to YouTube!

If you’ve ever dreamed of owning a personal jet, now is the time! The SubSonex extends the Sonex Aircraft 'Reality Check' philosophy to become the first truly practical and affordable personal jet for recreational flying. The first benchmark on the SubSonex 'reality checklist' is the fact that the aircraft is becoming a reality in the very near-term as an Ultra-Quick Build Kit, complete with engine, that leaves only the most minor items for the customer to source, and the most basic of construction tasks to complete. When you are flying a SubSonex, the $100 hamburger never tasted so good!

Ultra-Quick Build Kit for Experimental Exhibition Category:
The SubSonex Ultra-Quick Build Kit is intended for flight under Experimental Exhibition category rules. Without the "51 percent rule" restrictions associated with Experimental/Amateur-Built airworthiness certification, the SubSonex will ship with a pre-assembled fuselage, wings, tail and control surfaces with canopy and windshield installed. The SubSonex customer will install the easily removable outboard wing panels, engine and fuel system, bolt-in the retractable landing gear, install avionics, electrical systems and controls, install the supplied BRS full-aircraft recovery parachute system, pre-molded fiberglass components and upholstery, and add paint. Under Experimental Exhibition category regulations, SubSonex customers will also have the freedom to take advantage of builder assist centers or aircraft finishing services to do the work for them!

Just like our regular Quick Build Kits for the Sonex, Waiex and Onex, the SubSonex Ultra-Quick Build Kit assemblies will be constructed in Oshkosh, WI, the home base of Sonex Aircraft, and are regularly inspected for quality by Sonex Aircraft, LLC staff.

Experimental airworthiness certification under the Exhibition category is perfectly-suited to the mission of an aircraft like the SubSonex. There is no 'proficiency flight area' required for aircraft in this group of the exhibition rules, and this is an aircraft that you'll certainly want to show-off at organized events. You can either fly the aircraft cross-country to an event, or utilize the SubSonex's easily removable outboard wing panels to transport the aircraft in a compact trailer. Pilots used to flying warbirds, competition aerobatic planes, sailplanes or other specialized aircraft are well-versed when it comes to working within the operational restrictions for exhibition aircraft, and the kit construction freedoms afforded to aircraft in this category is a perfect fit for the desires of the likely SubSonex Personal Jet customer.

EAB Quick Build Kit Also Available:
For those desiring an Experimental Amateur Built kit, an EAB Quick Build Kit is also offered. The EAB Kit will include all featured mentioned above, however, customers will need to construct the aircraft tail and control surfaces to meet EAB eligibility. The major difference between amateur-built and exhibition certification lies in who must construct the major portion of the aircraft. The choice of whether or not the customer wishes to hire a professional builder or shop to complete the aircraft will typically be the deciding factor. For customers outside the US, the certification requirements of amateur-built aircraft as opposed to experimental exhibition aircraft may be a deciding factor. All other differences are relatively minor. A downloadable Experimental Exhibition vs. EAB Summary has been prepared to help SubSonex customers make their decision.

SubSonex Kit Delivery:
Like our regular Quick Build Kits, SubSonex Ultra-Quick Build Kits shipping to most areas of the lower 48 United States will ship via specialized transport, and do not need crating. International orders will be shiped via 20" FCL Container, and a container packing fee applies. Separate transportation expenses apply for all shipping options. See our Shipping/Packaging Page for more information about Quick Build Kit shipping.

About the Aircraft:
Nobody can deny that every pilot’s fantasy is to own and fly a jet! The SubSonex is designed to capitalize on new generation small turbine engines to give pilots of more average means the title of Jet Jock. SubSonex is all about taking a thrilling rocket ride around the neighborhood!

The SubSonex Personal Jet concept was first unveiled at AirVenture in 2009. After successful pairing with the PBS TJ-100 engine, the SubSonex JSX-1 prototype achieved first flight in August 2011 and completed a successful flight test program in 2012.

Read the SubSonex Test Pilot's Report in AOPA Pilot:

The SubSonex is featured in the December, 2012 issues of AOPA Pilot and Turbine Pilot magazines! The article, "Jet in a Box: Some Assembly Required" is written by SubSonex lead test pilot Bob Carlton and covers the SubSonex flight experience, as well as some of the aircraft's history and our plans for the future of the design.

JSX-2 Features:
Second-generation JSX-2 prototypes are currently under construction to serve as “conforming” prototypes representing the final SubSonex Personal Jet product. JSX-2 will incorporate many new features and enhancements, including fully retractable gear with a steerable nose wheel, a full-airplane ballistic parachute system, larger cockpit, increased fuel capacity and more:

  • Larger Cockpit: SubSonex JSX-2 aircraft will feature a larger cockpit using a straight section of parallel longerons which maintain the 24" cockpit width from the pilot's shoulders to the windshield bow.

    More instrument panel space allows
    modern EFIS systems or tablets!

    Using roughly the same overall dimensions, some changes in seating geometry add to the increase in cockpit width to offer more leg, knee and head room (above).

  • Larger Instrument Panel: The larger SubSonex cockpit allows for the installation of a larger instrument panel to fit a wider range of modern avionics, including iPad/tablet installation.

  • Ballistic Parachute Recovery System:
    JSX-2 includes a ballistic parachute full-aircraft recovery system. This eliminates the need for a pilot-wearable parachute, greatly improving seating comfort and further increasing available cockpit space.

  • Improved Lines/Aesthetics: Sculpted lines in the nose area of the aircraft combine with dimensional and geometric changes to the cockpit area to give the JSX-2 a far-more aesthetically pleasing appearance from nose to tail. Fully-Retractable Landing Gear also adds greatly to the aesthetics and performance of the design.

    The side view of SubSonex JSX-2 shows off the new variant's appealing lines: from the redesigned nose and cockpit, to the fully-retractable gear, to the sculpted look added by the tail strake.

  • Fully-Retractable Landing Gear: SubSonex JSX-2 aircraft will feature fully-retractable landing gear with steerable nose wheel. The retractable main gear uses dual-truck wheels for safety and redundancy at higher runway speeds with integrated hydraulic brakes similar in-design to the innovative and highly-successful AeroConversions AeroBrake system, and integrated shocks using urethane rods vs. higher-maintenance oil-filled systems.

    44 gallon rotationally-molded cross-linked polyethylene fuel cell.
  • Larger Fuel Capacity: The SubSonex will see increased fuel capacity of 44 US gallons using a rotationally-molded cross-linked polyethylene fuel cell, making for a very robust and rupture-proof tank design (right).

  • Easily-Removable Outboard Wing Panels:
    Removal of the aircraft's outer wing panels will be a one-person task that will be extremely simple and easy. The fuselage with wing center section will easily fit into an enclosed trailer along with the removed outboard wing panels.
Watch the SubSonex Webinar:

Sonex Aircraft, LLC Founder & President and SubSonex Personal Jet designer John Monnett held an informative EAA-hosted webinar in 2012. Catch this SubSonex webinar in archived video format on EAA's web site!

  • Autopilot Compatible: Although long cross-country flying isn't part of the SubSonex's intended mission, the aircraft's control system is fully-compatible with today's new generation of lightweight and compact autopilot units.

  • Optional Smoke System: The SubSonex JSX-2 design will feature an optional integrated smoke generator, further increasing the jet's fun-factor.

  • Optional Cabin Heat: After all, we can't expect you to be cruising a jet around at 10,000+ feet without it!
    An oxygen system will be optional too!

Same Great Engine: The PBS TJ-100 Turbojet!

The TJ-100 turbojet engine is produced by PBS Velká Bíteš of the Czech Republic, a large manufacturer of rotary machines with roots dating-back to 1814. The TJ-100 is designed for UAV, UCAV, experimental aircraft and motorized gliders with hundreds of units delivered since its introduction in 2008. The engine is a true "plug & play" package featuring integral ECU, starter/generator and oil system, and ships complete in the SubSonex kit with instrumentation, throttle control, pre-wired harnesses and other installation components. The 247 lb thrust engine continues to exceed the expectations of PBS designers and customers alike, with flawless performance and an outstanding service history, all backed by top-notch customer service. The TJ-100 can fit in a small crate to be economically shipped for service, and PBS can turn-around inspection and overhaul service orders in a single week.

Pilot Qualifications: How to Become a SubSonex Pilot!

Because there is no Type Certificate available for the SubSonex, pilots will need a Letter of Authorization (LOA) from the FAA that is specific to the aircraft. Working commercial pilots operating jet or turboprop aircraft can easily qualify for the LOA, and small aircraft currency can be provided, if needed, via Sonex Aircraft’s T-Flight Transition Training Program. Pilots without previous jet experience can also qualify after obtaining the appropriate training, and all prospective SubSonex customers are invited to contact Sonex Aircraft representatives to discuss their flight qualifications.
