Airframe MRO

AAR Airframe MRO delivers heavy maintenance, structural repair, modifications, and engineering services for commercial passenger and cargo operators. The network spans eight facilities in the United States and Canada — Greensboro NC, Indianapolis IN, Lake City FL, Miami FL, Oklahoma City OK, Rockford IL, Trois-Rivières QC, and Windsor ON — supported by engineering capabilities in Indianapolis, Greensboro, and Singapore. AAR holds FAA Repair Station approval and EASA Part-145 certification, making work performed at its facilities acceptable to both US and European regulators.

Capability covers the full range of scheduled heavy maintenance: C-checks, D-checks, and phased programmes on narrow-body Boeing 737 variants and Airbus A320-family aircraft (including A321neo), as well as wide-body A330 maintenance at Trois-Rivières. Structural and composite repairs, aging aircraft inspections, corrosion prevention and control programmes, and on-wing component inspections extend the scope beyond standard interval-driven checks. An in-house engineering team handles modification design, airworthiness certification, and integration work for interiors, structures, and electrical systems — enabling a single-provider path from maintenance concept to STC'd modification.

The network carries a multi-year backlog and has two active facility expansions underway at Miami and Oklahoma City. For GCC and international operators, AAR's scale as an independent (not airline-captive) provider means competitive slot access, transparent pricing, and a commercial relationship unconstrained by flag-carrier scheduling priorities. The Singapore engineering office provides a regional presence relevant to Asian-Pacific and Middle East operators routing aircraft for maintenance.
