AAR Corp. AIR

Company Overview

AAR Corp. is a U.S.-based aerospace and aviation services company that provides aftermarket products and services to commercial aviation operators, cargo carriers, government and defense customers, and original equipment manufacturers (OEMs). The company operates primarily in the aviation maintenance, repair, and overhaul (MRO) industry and generates revenue through aircraft maintenance services, parts supply, inventory management, and aviation logistics support. AAR serves airlines, defense agencies, and aviation operators globally, with a strong emphasis on operational readiness and supply chain efficiency.

The company traces its origins to 1955 and evolved from an aircraft parts operation into a diversified aviation services provider. Over time, AAR expanded through acquisitions, organic growth, and long-term service contracts with airlines and government agencies. Its positioning in the independent aftermarket aviation services sector provides flexibility across multiple aircraft platforms and customer types, distinguishing it from OEM-affiliated competitors. The company’s business model benefits from recurring maintenance demand, fleet aging trends, and ongoing global air traffic growth.

Business Operations

AAR organizes operations primarily across aviation services businesses including Parts Supply, Repair & Engineering, and integrated aviation support solutions. Revenue is generated through aircraft component distribution, MRO services, aircraft modifications, inventory management programs, and logistics support contracts. The company operates maintenance facilities and supply chain hubs supporting both commercial and government aviation customers. Its capabilities include airframe maintenance, component repair, landing gear services, engineering solutions, and aircraft lifecycle support.

The company maintains operations across the United States and internationally, supporting customers in commercial aviation, cargo transport, and defense sectors. AAR controls specialized aviation inventory, repair infrastructure, and logistics systems that support fleet availability and mission readiness. Key subsidiaries and operational platforms include Trax, an aviation maintenance software business acquired to strengthen digital maintenance capabilities, and multiple FAA-certified repair stations. AAR also maintains strategic relationships with airlines, OEMs, and government agencies, including support programs tied to the U.S. Department of Defense and allied international defense organizations.
