AAR Corp. AIR

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.
