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 requires a complete 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 FAA requirements.

• The Articles of Agreement and Waiver of Liability can be downloaded here: http://www.sonexaircraft.com/documents/liability.pdf
• FAA Form 8050-2 can be downloaded here (pdf format) -or- the 8050-2 Form supplied to the original kit purchaser may be used: https://www.faa.gov/documentLibrary/media/form/ac8050-2.pdf

If you did not receive the original document from 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 Sonex staff.
• 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 order parts for your airframe via the Sonex Web Store.
• Access to technical support, or placing of orders will not be allowed until the ownership transfer process is complete.
• Complete Sonex Kits and Flying Aircraft share the serial number of the set of plans they are purchased under. Therefore, whenever a Sonex kit or flying Sonex aircraft 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, as the aircraft's serial number has been permanently retired in our system. 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.

International Ownership Transfer and Plans Building Availability: Sonex A-Model Plans-Only (scratch building) Ownership Transfers are only available to customers in the United States, Canada, Australia and New Zealand. Complete Airframe Kit and Sub-Kit projects along with flying aircraft are eligible for transfer in all countries worldwide.

Buyer beware: Only one set of Spar Caps are sold per plan serial number. It is the buyer's responsibility to check with Sonex, LLC to ensure Spars have not been previously sold under the prospective buyer's serial number.

Make Sure You're Getting a Good Deal: Read Sonex guidance and important safety advisories on Buying New vs. Used kits and aircraft.

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.

This, and all other transactions subject to Sonex, LLC's full Terms & Conditions.
