Happy Birthday Chris Heintz 


Today is the 78th birthday of the founder of Zenith Aircraft, Chris Heintz. While I have great admiration for the legendary designers of experimental aircraft, and I have had the good fortune to meet Wittman, Rutan, VanGrunsven, and Monett, I can say without the slightest hesitation that Chris Heintz has a greater impact on my work in aviation simply because I learned more about the design of aircraft from him.


I “met” him nearly 30 years ago, through a series of articles he wrote for the EAA publication Light Plane World. The articles demonstrated three things very clearly: He wrote to educate, not impress readers; He had values, refusing to design planes with stall speeds that precluded survivability;  and sharing what he knew was a vital part, maybe even his primary mission in aviation. I read these as a freshman at Embry Riddle, in the periodical section of the library. I appreciated them greatly, but could never have imagined the long term impact of the mans work on my years ahead in aviation. For this, I remain most grateful, and I join thousands of other aviators in celebrating the life’s work of Chris Heintz.

Aircraft design is a field that draws people with strong egos and yet to be explored social skills. In this arena, Chris Heintz stands out completely against the norm. Without question, he is the most approachable and modest of all the major designers I have ever met.

About William Wynne
I have been continuously building, testing and flying Corvair engines since 1989. Information, parts and components that we developed and tested are now flying on several hundred Corvair powered aircraft. I earned a Bachelor of Science in Professional Aeronautics and an A&P license from Embry-Riddle Aeronautical University, and have a proven 20 year track record of effectively teaching homebuilders how to create and fly their own Corvair powered planes. Much of this is chronicled at www.FlyCorvair.com and in more than 50 magazine articles.

    In 2014 we had the opportunity to meet and talk with Chris Heintz during the One Week Wonder build at Oshkosh. He is simply a humble and passionate person. I wish I knew French better as it would have been great to gain insight through language. On a personal level it was also interesting to find that his specialty in the French Air Force was basically what I did in the USAF.
    Happy birthday for Chris!
    Harold and Edi
