Active in aviation already since the early eighties, Koolhaas Alphen has spent over 30 years providing aviation support on specific aircraft types to a global customer base.

As our expertise and reputation have grown, we have become known for our ability to comply with government and military tenders, which has resulted in us being awarded a number of high-value contracts.

Today, we provide mostly civil aircraft operators with one of the most reliable aviation-maintenance management and parts-supply services offered anywhere within the industry.
