Key Takeaways:
Sonex Aviation, formerly Sonex Aircraft, has been relaunched under new ownership (ON Capital Inc. led by Stephen Osborne) after shutting down in March due to a severe drop in sales.
The company is actively "back in business," shipping parts and kits, resuming flight tests, and scaling up production with 12 staff.
Sonex Aviation has improved its supply chain by acquiring a key precision machine parts supplier, and customer reaction to the restart has been largely positive.
Development of the new Sonex Highwing is nearing completion, with wing kits expected to ship in late July and fuselage kits shortly after.
Sonex Aviation will be at EAA AirVenture in July in Oshkosh, Wisconsin.
The company, formerly known as Sonex Aircraft, shut down in March. Then on May 1, it was announced that all assets of Sonex Aircraft, including the Sonex Aerospace and AeroConversions lines, had been acquired by ON Capital Inc., led by Stephen Osborne.
