AAR, a provider of aviation services to commercial and government operators, completed the acquisition of Trax, an independent provider of aircraft MRO and fleet management software. Financial terms were not disclosed. “We believe we can support Trax’s continued growth by investing in its platforms and by leveraging our global relationships to help Trax reach additional customers. We also believe that over time this combination will allow more customers to better access AAR’s parts and services offerings as Trax is the materials management system used by thousands of buyers and planners at airlines around the world,” John M. Holmes, AAR Chairman, President, and CEO.
