Buying Previously Owned Sonex Plans and Complete Kits:
Sonex Plans that have not been used to build an Airframe may
be resold. In order for Sonex, LLC to recognize the transfer of ownership,
three actions must be taken. One by the Seller and two by the Buyer:
Seller: The Sonex Articles of Agreement and
Waiver of Liability requires the seller to notify Sonex, LLC of the
ownership transfer in writing. This is most easily accomplished by
messaging and submitting documents to the Orders/Customer
Service department via the Sonex Contact Form.
Buyer: The buyer (new owner) must sign and
return their own completed copy of the Articles of Agreement and Waiver of
Liability (http://www.sonexaircraft.com/documents/liability.pdf) along
with a $100 ownership transfer fee. Copies, faxes and email attachments are
accepted, as long as they are legible. Please see the Payments Methods section of our Terms & Conditions for payment instructions. Please leave all seller
signature lines blank. Sonex is always considered the seller and will
sign the documentation when it is received. Note: If the buyer is
purchasing a complete kit or flying aircraft, then a copy of the signed FAA
Bill of Sale (Form 8050-2) must also be included with the Planholder Buyer
Agreement. The FAA values the chain of ownership with all kit aircraft and
aircraft registration can become very difficult if this chain is not
documented by all owners. We encourage all individuals involved the
ownership transfer process to visit (http://www.faa.gov) for more information on
If you did not receive the
original document form the seller, or do not have access to it, Sonex will
re-initiate the chain of ownership by issuing a new copy to the original
owner. From there, it is the responsibility of the new owner to ensure all
previous owners are documented and signed.
Once the signed Articles of Agreement and Waiver of Liability
and ownership transfer fee are received from the new owner and written
notice of the transfer of ownership is received from the seller, the new
owner assumes all of the rights and privileges of the original purchaser
with two exceptions:
- No parts exchanges are accepted from
second-hand kit/parts owners.
- Part warranties are not
transferrable to new owners.
Other Notes on Plan Transfers:
- Ownership transfers typically take 5-10 business days to
process, beginning from the first day that all requirements are received by
- Once a transfer is complete, you will be notified via email
with a PAID invoice for your ownership transfer fee. Upon receiving this
email notification, you will be able to create
a Sonex Web Store account and be granted Sonex aircraft
Plans Owner membership status, allowing you to access all restricted Web
Store product categories.
- Access to technical support, or
placing of orders will not be allowed until the ownership transfer process
- Complete Sonex Kits share the serial number of the set of
plans they are purchased under. Therefore, whenever a Sonex kit is re-sold
or transferred, the set of plans they are purchased under is part of that
transaction and must remain with the kit.
- Any amount due to Sonex under the Serial Number must be paid
before an ownership transfer is allowed.
- Any Sonex aircraft that is known to have been heavily
damaged in an incident or accident is not eligible for ownership transfer.
Component parts may be salvaged from the aircraft and used on a new serial
number purchased from Sonex.
- The last registered owner of the plans will be held
accountable for any use of the plans or parts that violate intellectual
property laws and/or Articles of Agreement and Waiver of Liability terms.

Buying Flying Sonex Aircraft:
Any Flying Sonex Aircraft carries the Serial number of the Sonex Plans used to build it. In order for the flying aircraft ownership transfer to be recognized by Sonex, LLC the procedure for Buying Sonex Plans (above) must be followed by Buyer and Seller. The Sonex Plans (print set) must travel with the aircraft being sold. It is the responsibility of the buyer to make sure the plans are with the flying aircraft at all times. Part warranties are not transferable to new owners, and parts exchanges are not accepted.
Note: we recommend that all Sonex Aircraft owners utilize their own buyer agreement when selling Experimental Amateur-Built aircraft, such as the template provided by EAA on their Members Only web site (log-in required): http://members.eaa.org/home/homebuilders/selling/waiver.html
