Wolfgang Dillbaum-Alexius, born in 1961 in Krefeld, Germany, is the visionary founder of aps. With a career spanning several decades in the aviation industry, Wolfgang’s journey is marked by significant milestones and an unwavering commitment to excellent customer service.

His aviation career began at Rheinland Air Service (RAS). From 1986 to 2002, Wolfgang was instrumental in establishing and expanding the spare parts business and logistics at RAS. His leadership skills led him to become the Managing Director of the company in Mönchengladbach from 1996 to 2002. During this period, he honed his expertise in the procurement and distribution of aviation parts, laying the groundwork for his future ventures.
In 2002, driven by an entrepreneurial spirit and a keen understanding of the market’s needs, Wolfgang founded aps. His goal was clear: to provide high-quality aviation spare parts at affordable prices. His vision quickly took flight, and aps grew to become a trusted name in the industry. Between 2002 and 2003, while serving as the Director of Material Management for Jet Aviation in Düsseldorf, Wolfgang focused on building aps from the ground up.

From 2004 to 2009, Wolfgang’s passion for aviation led him to manage multiple ventures, including Piper AG, RAS-Parts GmbH, and Piper Parts UK. However, in 2009, he decided to dedicate himself entirely to aps, steering the company towards rapid growth and success. As the sole shareholder, Wolfgang’s leadership has been pivotal in positioning aps as a European leader in aviation spare parts procurement and logistics.

Wolfgang’s engagement extends beyond his company. He is an active member of several prestigious organizations, including the German Association of General Aviation Companies (BBAL), the Aircraft Parts Distributors and Manufacturers Association (ADMA), and the Federal Association of Small and Medium-Sized Enterprises (BVMW). His contributions to the industry were further recognized when he served as the president of ADMA between 2019 and 2021.

Wolfgang Dillbaum-Alexius’s journey is a testament to his dedication, expertise, and vision. His leadership continues to inspire the aps team, driving the company towards new heights in the aviation industry.
