Aar Corp
A global aviation aftermarket provider, AAR keeps aircraft flying by supplying new and used parts, repairing and overhauling airframes and components, and selling maintenance software to airlines and MRO shops worldwide. It also builds AI tools like its Airvoyant procurement platform. The company started in 1951 when founder Ira Allen Eichner began selling surplus radios from his fiancée's borrowed capital in Chicago; renamed Allen Aircraft Radio in 1962, it eventually adopted the initials as its name. That university student's tiny parts business grew into one of the largest aviation-services firms in the world.
