Levan Tabidze

Vice President of Engineering

Great ag planes start with great engineering and Levan Tabidze is, by any measure, in that category. Levan oversees our engineering department here in Albany and is responsible for certification as well as new product design, development and production support. He brings more that 30 years of experience in aircraft engineering, design, and certification programs to bear on behalf of every Thrush we build, and his experience in product support greatly enhances our capabilities there as well.
