"Be true —

work wisely and look to the outcome.“

My former naval air squadron's emblem

Loyalty, Courage, Readiness, Reliability, Endurance

both perfectly complemented by:


"UPON MY HONOR I swear that the rights and privileges conferred to me as a licensed aviation engineer will be held in the highest regard. I would never put others in risk that I wouldn't take on for myself or for those dearest to us, since I'm perfectly aware that their safety and wellbeing depend on my skill and judgment."

Rachel's Aviation Journey:

From Playing with Balsa Wood Planes to Aircraft Expert and a Seasoned Team of Innovators in Aviation

My personal story begins around 1970 with a child's fascination, gazing out of a roof window at pilots adorned in red helmets, soaring at tree-top level. That image ignited a passion in me, leading to the creation of my first aircraft — a balsa wood plane propelled by nothing more than a rubber band. This childhood wonder laid the foundation for a lifelong journey in aviation.

After completing my apprenticeship as an aircraft and powerplant (A&P) mechanic and earning my Pilot License, my dedication to aviation only grew. Today, after nearly fifty years in this thrilling industry, I am honored to serve as a publicly appointed aircraft expert witness and chair the appraiser association for the German-speaking countries in Europe. Each day, whether in the hangar or the sky, performing check flights or inspecting aircraft for my clients, reaffirms my love for aviation and for the people who make it possible — the pilots, engineers, accountants, and enthusiasts who share this dream.
