Leadership Team

Jon Jeffery
President & CEO

Jon leads Hummingbird Aero following a successful career of 35 years focused on aircraft hydraulic systems and flight control actuation. Prior to Hummingbird, Jon spent 27 years with Parker where he initiated and led Parker’s entry into developing full aircraft hydraulic systems. During this time, Jon was instrumental in the award and development of over 22 aircraft hydraulic systems.  

Jon began his career in 1981 with McDonnell Aircraft Company, St. Louis, Missouri,  as a hydraulic system design engineer during the early phase of the F/A-18 aircraft. Jon worked on a number of emerging technologies including 8000 PSI hydraulic systems, enhanced dynamic stiffness for flight control actuators and variable pressure pumps. At McAir, Jon quickly moved up through positions of hydraulic team leader for the A-12 and then as Unit Chief, Flight Controls & Hydraulic Systems for the F/A-18 programs. 

Jon joined Parker in 1992 as Director of rotating product development, and quickly saw the potential to supply entire aircraft hydraulic systems. Over the next years, Jon spent significant time in France, Russia, Brazil and Asia developing strong relationships with nearly every global OEM aircraft supplier. Jon is a recognized authority on aircraft hydraulic systems development, and brings this expertise through to the Hummingbird client base.  

Jon served for 8 years as President of the SAE A6 International Committee for Aerospace Actuation, Control and Fluid Power Systems. He holds a patent for a novel energy recovery system for electrohydraulic flight controls.  ​
