Sonex Builders & Pilots Foundation

The Sonex Builders & Pilots Foundation is a national type club for builders and pilots of Sonex Aircraft designs founded to promote safety and education in building and operating Sonex aircraft. The Foundation, in conjunction with Sonex Aircraft LLC, has published a Flight Training Syllabus for Transition Training in Sonex Aircraft.

Read more about the Foundation in our Official Press Release.

The Sonex Builders & Pilots Foundation typically participate in the Great Lakes Sonex Fly-In held in June. Additionally, their Annual Membership Meeting is held each year during EAA AirVenture Oshkosh.

American Sonex Association

The American Sonex Association was founded by Sonex builder John Davis in September of 2004 as a way to provide the Southeast with a place to look at, fly in, and talk about the Sonex Aircraft. The entire purpose of the ASA is to provide help, encouragement, and special tools to Sonex builders where ever they might reside.

The ASA's flagship event is the annual Crossville Fly-In, held in October every year. The Association also hosts the annual North Carolina Spring Fling fly-in.

Florida Sonex Association

The Florida Sonex Association was founded in 2008 by Sonex builder Mike January to provide a safe and fun filled membership within Florida and surrounding states, to encourage their flying members to sponsor FSA fly-in events at their home airports, provide assistance to Sonex Aircraft pilots and builders in need if they become stranded or need assistance in construction within the state of Florida, as well as all member states and Canada (members who reside part-time in Florida, as well as other locations).

The FSA's flagship event is their annual Dunnellon Fly-In, held in November. The Association also hosts the annual Spring Sonex Fest, timed to provide an oustanding Sonex event for Sun 'n Fun attendees. In addition, the FSA members host several smaller "Member Home Airport" events throughout the year.

SonexAus (Australia)

SonexAus supports the owners and builders of the Sonex family of homebuilt aircraft. It aims to promote the building of Sonex aircraft as a recreational and educational pursuit and to advocate for the interests of Sonex owners and builders. SonexAus provides a wide range of practical assistance, information and social activities and flyins for the benefit of members and friends. SonexAus will maintain appropriate and effective working relationships and affiliations with SAAA, RAAus, AOPA and other relevant organisations and, if required, represents the interests of Sonex owners and builders with relevant government regulators.

SonexAus hosts an annual fly-in at Yarrawonga as their flagship event. SonexAus also is an exhibitor, and holds their annual meeting at the Recreational Aviation Australia (RA-Aus) National Convention (Natfly). Additional SonexAus events and fly-ins are organized throughout the year.

SonexEuro (Europe)

SonexEuro was founded in 2012 by UK builder Steve Moody to build the Sonex community across all of Europe.

No SonexEuro events have been scheduled at this time.

May 17, 2014: 1st Annual Sonex Mile-High Fly-In
Colorado Springs East Airport (CO49 Fr. A50) Colorado Springs, CO

Fellow Sonex Builders, Pilots and Friends,

I'm pleased to announce the first-annual "Sonex Mile-High Fly-In"! Please come join builders and pilots from all across Colorado and the Rocky Mountain region for an afternoon of camaraderie and information sharing.

The event will be held May 17, 2014 near Colorado Springs, CO, at Springs East Airport (A50, or more recently CO49). Fly-in's and Drive-in are welcome! Arrivals will start around 8:00 am, and the programs at 10:00am. We'll have drinks and snacks available all day, and we'll fire up the BBQ for lunch with burgers and dogs.

The presentations will be informal and interactive, allowing current builders and pilots the chance to pass along what they've learned to others. Some of the topics may include "Building a Xenos", "Converting Tri-gear to Taildragger", "Jabiru FWF Installation Tips" and a review of the plans and building process. Several of our local pilots plan to give "Sonex Smile Rides" as a way to show off the attraction of a Sonex and to hook future builders!

Springs East Airport is situated south of Denver's airspace at the foot of the Rocky Mountains. It's easy to get in and out, and makes a great destination. If you plan to stay overnight, accommodations are close by and dry camping is available on the field.

Come out and support the Colorado Sonex Mile-High Club and make some new friends in the process! I look forward to a great turnout.

May 31, 2014: 11th Annual Northern California Sonex Fly-In
Rio Linda Airport (L36) Rio Linda, CA

NorCal Fly-In at Rio Linda: See the Report from Last Year's Event!

May 31st 2014 is the date. BBQ Ribs along with dogs and burgers and assorted fixins. Airplanes of all types invited. Hope to see over over a dozen, possibly as many as 20 Sonex examples including at least one Onex. AeroV's, Jab 2200 and Jab 3300 Sonex/Waiex will be there. Flour bombing and spot landing contests. Come early and watch as some of us come from landing on 100x4000 ft runways to this quaint little 35x2300 span. Mistakes will be made, but hopefully all will be small and harmless. Personally, I have landed 2 or 3 times on a single approach there. Great group of folks turn out, usually 100-150+.

June 7, 2014: North Central Sonex Fly-In
Buffalo Municipal Airport (KCFE) Buffalo, MN

We are organizing a regional Sonex fly-in at the Buffalo Airport, Buffalo, Minnesota. This is a convenient and active airport, located west of Minneapolis, outside Class B airspace. EAA Chapter 878 hosts meetings and events at Buffalo, as well as their original home of Maple Lake, Minnesota.
While open to all, the fly-in would primarily be for Sonex pilots and builders located in the upper Midwest (Minnesota, Iowa, North Dakota, South Dakota, western Wisconsin, Manitoba and western Ontario), plus anyone else interested in learning more about the Sonex line of Experimental aircraft.

Great Response: Thanks to all pilots, builders and others interested in the Sonex line of aircraft who responded to my initial posting/inquiry about hosting a Sonex Fly-In at the Buffalo Municipal Airport on June 7, 2014. The response far exceeded my expectations!

Fly-In Agenda: I’m trying to develop an agenda that will appeal to those who are already flying their Sonex, as well as something that will provide interest and instruction to those who are in the build process, or now considering a building project. For the current builder/pilot, it may be sufficient just to have a destination to fly to, the chance to "show off" their airplane and do some hangar flying. But others may expect more hands-on or technical experiences. Let me know if you have thoughts on this or would be interested in making a presentation. Fly-in hours to be determined.

One thing is for sure – LUNCH!! We will have lunch available to registered guests, and I’m striving for something more enticing than burgers/brats!

Parts and Tools Swap/Sale: If you have tools, parts, raw materials, instruments, etc. (Sonex appropriate only, please), let me know. We may set up a table at the fly-in for this, or perhaps establish an "on-line" swap meet. You would be responsible for pricing and your sales table.

Buffalo Fly-In: The Sonex Fly-In on Saturday will precede the Buffalo Fly-In, Air Show and Car Show on Sunday, June 8. This is one of the kick-off events for the weeklong Buffalo Days community celebration and it always draws a crowd. Plan to make it a weekend!

Airspace Around Buffalo: The Buffalo Airport lies outside of Class B airspace, so anyone uncomfortable with getting close to MSP can plan their approach accordingly.
If you are interested in attending this fly-in and would like to be added to an email information and invitation list, please respond to Wayne Flury at, or call 763-670-6021.  Let me know what fly-in activities would entice you to attend. For persons who are willing and able, I also solicit your possible participation in the fly-in as a speaker, demonstrator, vendor, etc.
Please help to spread the word!

July 28, 2014, 11am:
2014 Sonex Builders and Pilots Foundation Annual Membership Meeting
EAA AirVenture Oshkosh, at Sonex Booth

See the Report from Last Year's Meeting on SBPF Web Site.

Greetings Fellow Sonex Enthusiasts,

Now that we've reached July, your board members at the Sonex Builders and Pilots Foundation are hard at work preparing the Oshkosh AirVenture 2014 airshow. We're pleased to announce that this year's annual Membership Meeting will once again be held at Oshkosh on Monday, July 28th, the opening day of the show.  

Here are the details:

  • 2014 SBPF Annual Membership Meeting
  • Located at the Oshkosh flight line adjacent to the Sonex Aircraft, LLC display
  • Monday, July 28th, 2014.
  • 11:00 a.m. Local time

We hope that anyone who is a member of the SBPF, has an interest in joining, or has an interest in Sonex aircraft is able to attend.  We plan on offering updates to our current status, offer insights on future events, and if you're a voting member, this year will be an election of Michael Farley to a three-year term as a director of SBPF. Please plan on attending this important event!

One important item on the agenda we'd like to bring to your attention is the possibility of the SBPF establishing affiliations with other dedicated Sonex clubs.  In recent months, the Sonex Builders and Pilots Foundation board members have received several requests from various regional and local Sonex associations with regards to the possibility of forming an affiliation between the SBPF and these independent groups.

In response to these requests, the board members reviewed the original bylaws and realized they do not address the proposed affiliation of independent groups, so we are asking for member input.

The question we'd like to ask our members is, do we want to expand our official affiliations to share resources, membership, and information with regional organizations that have Sonex-related events?  Overall, the board members are generally in favor of the prospect of clubs joining together because of the increase in participation of the community, as well as the ability for owners and pilots to more easily share stories and information.  The ability for the Sonex community to expand even further is a very exciting idea!

As we considered our possible options, we took a few moments to review our mission goals when the Foundation was first created.  As we already stated, one very important goal, decided on upon the establishment of the Foundation, was that we did not want to take over, compete with, or in any way direct any established group, regional organization, or association such as the American Sonex Association (ASA), Florida Sonex Association, etc.  As such, one aspect of consideration is that the board of directors has already decided that we do not want to get involved in exchanging money or administering the activities of these organizations.

Ultimately, we are requesting our members determine whether or not the Sonex Builders and Pilots Foundation expand our official affiliations to address these requests.

We welcome comments as well as any points of discussion our members wish to address during this year's membership meeting.  If you’re unable to attend Oshkosh but have input about the affiliation discussion, please comment on the thread posted to or by contacting one of the SBPF officers.

Thank you for your consideration, and we look forward to visiting with you at Oshkosh 2014!
Robbie Culver, President
Michael Farley, Vice President
Eric Seber, Secretary
Carl Orton, Treasurer

September 6, 2014: 6th Annual Northeast Sonex Fly-In
Dillant-Hopkins Airport (KEEN) Keene, NH

If you have an interest in the Sonex aircraft; if you just like airplanes and enjoy hanging around airports; if you live in the New England/Northeast area, then this event is for you!

This event was conceived because there are now a doznen or more flying Sonex/Waiex/Xenos aircraft in the area, and even more active builders, as well as those considering building. That would include the latest ONEX aircraft!
