Josef Horvath, M.Sc. Aerospace Engineering
Founder & Director – International Aerospace GmbH
Josef brings over 38 years of distinguished experience in international civil aviation certification, compliance, and aviation law. Bridging the gap between high-level regulatory strategy and rigorous physical engineering, he is a rare industry expert who combines an advanced M.Sc. in Aerospace Engineering with full certification as an FAA Airframe and Powerplant (A&P) Mechanic.
As an EASA-accredited Head of Design Organisation (HoDO), Head of Airworthiness (HoA), and Compliance Verification Engineer (CVE), Josef has built trusted, decades-long relationships with civil aviation authorities around the world. His structural leadership goes far beyond managing internal departments; he specializes in creating entirely new Design Organisation Approvals (DOAs), writing comprehensive DOA handbooks, and establishing operational frameworks for entire companies from the ground up.
Throughout his career, Josef has directed complex modification and certification programs from initial concept to final authority approval. He offers comprehensive, end-to-end testing and validation lifecycle expertise, with deep hands-on experience developing test plans, securing authority sign-offs, executing physical testing (including Stress, Thermal, Life Cycle, and Fire tests), authoring validation declarations, and closing final FAA/EASA certification loops.
Under his leadership, International Aerospace GmbH consistently delivers measurable results, drastically reducing program cost, timeline, and risk while maintaining unyielding technical precision and regulatory integrity.
Meet the Team
At International Aerospace, we are more than a group of engineers; we’re a team of colleagues and long-time friends who have worked side by side across many projects and challenges over the years.
Our shared history in aviation design, testing, and certification has built a deep sense of trust, respect, and understanding that defines how we work today.
Each of us brings specialized expertise, from avionics, electrical systems, and structural testing to certification, software, and project management, but it’s the way we combine our experience and support one another that truly makes us strong.
Together, we turn complex engineering goals into clear, practical solutions, and we do it with the same passion that first brought us into aviation.
