Sonex Aircraft has revived the Sonerai, John Monnett’s original plans-built sport aircraft.
According to Sonex officials, plans and parts are now available for the Sonerai I, Sonerai II, and Sonerai IIS aircraft.

The Sonerai is the aircraft that started it all for John Monnett. Sonerai I was designed by John for competition in the Formula Vee air racing class and made its first flights in 1971, company officials noted on the Sonex website.
“After people began requesting plans for the aircraft, John was in business,” the statement continues. “The Sonerai was eventually offered in several configurations, including 2-seat variants, mid-wings, low-wings, and a stretched fuselage variant.”
Thousands of Sonerai aircraft have been built over the past 40 years, officials added.
The new efforts are supported by Fred Keip, Sonerai newsletter editor for many years.
