AAR (AIR)

The company’s activities span several complementary areas. Its parts supply business sells and leases used serviceable material and distributes new replacement parts sourced from original equipment manufacturers. This gives airlines and maintenance providers access to components that can reduce downtime and support cost-effective fleet operations. AAR also provides repair and engineering services, including airframe maintenance, component repair, and landing gear overhaul, placing it within the broader maintenance, repair, and overhaul market.

AAR’s government and defense work is an important part of its profile. Through integrated solutions, the company manages supply chains, supports customer-owned aircraft, and delivers performance-based logistics programs, including work for the U.S. Department of Defense. Its expeditionary services operations support the movement of equipment and personnel for U.S. and allied governments, as well as non-governmental organizations operating in challenging environments.

The company’s distinctive position comes from combining parts distribution, technical maintenance capability, and outsourced fleet support. Rather than relying on a single aviation cycle, AAR participates across aftermarket demand, defense readiness, and logistics services. Its business is closely tied to aircraft utilization, airline maintenance spending, military procurement priorities, and the need for reliable supply chains in global aviation.
