AAR Corporation Expands Aviation Maintenance Software with Aerostrat Acquisition

AAR Corporation’s Strategic Acquisition of Aerostrat: Expanding Digital Capabilities in the Aviation Maintenance Software Market

On August 12, 2025, AAR Corporation announced the acquisition of Aerostrat, a Seattle-based aviation maintenance planning software provider, for $15 million plus contingent consideration. This move marks a significant milestone in AAR’s ongoing digital transformation strategy, following its 2023 purchase of Trax, a leading aviation maintenance enterprise resource planning (ERP) software company. The acquisition occurs against the backdrop of a rapidly evolving aviation maintenance, repair, and operations (MRO) software market, which is projected to reach $11.68 billion by 2032. As airlines and MRO providers increasingly adopt advanced digital tools to optimize operations and ensure regulatory compliance, this transaction positions AAR to offer a more comprehensive suite of solutions.

The aviation MRO software sector is experiencing robust growth, driven by technological innovation, increasing fleet sizes, and heightened regulatory demands. By integrating Aerostrat’s long-range maintenance planning expertise with Trax’s operational ERP systems, AAR aims to deliver end-to-end digital solutions for airlines, cargo operators, and MRO providers. This analysis explores the significance of the acquisition, the strategic rationale behind it, and its implications for both AAR and the broader aviation maintenance industry.

The deal not only reflects AAR’s commitment to digital innovation but also highlights ongoing trends in aviation: the need for predictive maintenance, efficient resource allocation, and compliance with complex regulatory requirements. As the industry faces challenges such as labor shortages and supply chain disruptions, comprehensive Software platforms like those now offered by AAR are expected to play an increasingly vital role in supporting operational resilience and growth.

Market Context and Industry Dynamics

The global aviation MRO software market has undergone significant transformation in recent years. Industry analyses estimate the market size at between $7.64 billion and $8.13 billion in 2025, depending on methodology and scope, with projections ranging from $9.36 billion to $11.68 billion by 2030-2032. This reflects compound annual growth rates (CAGR) of 2.2% to 5.3%. The U.S. market alone, which accounts for a substantial share due to its large Commercial-Aircraft fleet, is forecasted to grow from $3.37 billion in 2025 to $4.18 billion by 2030, at a CAGR of 4.39%.

Several factors drive this growth: the expansion of airline fleets, particularly in Asia-Pacific; the post-pandemic rebound in air travel; regulatory pressures; and the adoption of advanced technologies such as artificial intelligence (AI), machine learning, and cloud-based platforms. MRO providers currently hold the largest market share, about 59% in 2024, due to their intensive software needs, while the airline segment is rapidly expanding as operators modernize fleets and streamline operations using digital tools.

Regional trends are noteworthy. Asia-Pacific is expected to lead global growth, propelled by rapid fleet expansion in China and India. This region now operates approximately one-third of the world’s aircraft and is anticipated to increase its share further. North-America, while currently holding a 27.53% share, may see its dominance challenged as emerging markets continue to invest in aviation infrastructure and technology.

“The aviation MRO software market is projected to reach $11.68 billion by 2032, underscoring the industry’s accelerating shift toward digital transformation and predictive maintenance technologies.”
