Scratch Building

Some aircraft builders are interested in building from plans without purchasing an aircraft kit.

The Legacy (A-Model) Sonex is available for plans or “scratch” building.* Scratch builders can purchase Sonex plans and build the entire aircraft from raw materials,** or they can purchase any of the components or Scratch Building Materials Kits below at any point in their project:

Plans Laser-Cut Metals Kit Rib and Bulkhead Kit Formed Aluminum Kit Matched-Hole Formed Parts Kit Machined Spar Caps Optional Pre-Assembled Main Wing Spars Machined Tail Spars (Sonex only) Welded Component Kit Machined Angle Components Aluminum Angle Bundle Canopy and Windshield Canopy and Windshield Bows

Those interested in scratch-building the Legacy (A-Model) Sonex may order any of the above materials kits after purchasing plans. Note: Scratch Building is only available for Legacy (A-Model) Sonex.

*Scratch Building Availability:
Sonex Plans are available for individual purchase only to customers in the United States, Canada, Australia and New Zealand. Customers in all other countries may only build using a Sonex Aircraft Complete Airframe Kit, Sonex Aircraft Sub-Kits, or Quick Build Kits.

**Sonex spar caps are made from a proprietary extrusion and must be purchased from Sonex to build the aircraft.
