Key Takeaways:

Sonex Aircraft abruptly ceased operations on March 27, surprising its community of kitplane builders and owners who are now grappling with how to complete unfinished projects and source parts.
The company's owner attributed the immediate shutdown to a "perfect storm" of financial pressures, including a severe drop in sales, increasing costs, and competition from their own used aircraft.
Despite widespread disappointment and practical concerns, the community has shown significant sympathy for the owner, and Sonex leadership is actively seeking investors to support the fleet and potentially resume operations.

Still stinging with disappointment and surprise, builders and owners of Sonex kitplanes are regrouping and hoping that reports of potential saviors are true, following the company’s abrupt announcement on March 27 that it was ceasing operations, effective immediately.

Discussions on sites and forums including SonexPilots.org and the Experimental Aircraft Channel’s Facebook page indicate builders are adapting to the shutdown by seeking to source parts directly from vendors and advising each other on how they might complete unfinished projects without factory support.
