Growth in MRO Services in the Baltics and Eastern Europe
The Maintenance, Repair, and Overhaul (MRO) sector in the Baltics and Eastern Europe is undergoing significant expansion, driven by increasing air traffic and the strategic development goals of regional airports. Although MRO is inherently a globalized industry, this region is emerging as a notable player due to its above-average aviation growth and competitive labor costs for highly skilled maintenance personnel.
Sofia Airport: A Regional MRO Leader
A key illustration of this growth is Bulgaria’s Sofia Airport. In late 2024, SOF Connect, the airport’s operator, hosted Aviation-Event 2024 SOF, marking Bulgaria’s first large-scale international aviation conference. The event served as a platform to unveil plans for a new Terminal 3, with a particular emphasis on expanding MRO facilities as a central investment focus.
Jesus Caballero, CEO of SOF Connect, highlighted the strategic advantage of airports offering on-site MRO services amid supply chain challenges affecting the airline industry. He noted, “It is difficult to develop such services at airports, but in Sofia we are one of Europe’s MRO leaders.” Currently, Sofia Airport services approximately 500 aircraft annually and employs around 2,000 technicians and engineers through major companies such as Lufthansa Technik and Aero Technic BG.
Having secured its MRO credentials through stringent regulatory and certification processes, Sofia is leveraging this expertise to position itself as a regional hub. Caballero emphasized the sector’s economic significance, stating that MRO activities generate about €130 million in annual turnover from five to six companies based at the airport. He expressed confidence that Sofia could become Europe’s largest MRO hub.
To realize this ambition, Sofia Airport plans to expand its MRO infrastructure substantially. Airlines increasingly prioritize airports where maintenance can be conducted efficiently to reduce costs and enhance operational reliability. The airport intends to add at least 10 new MRO hangars to the existing 19, while continuing to attract long-haul carriers seeking dependable on-site maintenance services.
Lufthansa Technik Sofia, operational since 2008, has grown to become the largest MRO base outside Germany for its parent company. Preslav Milchev, CEO of Lufthansa Technik Sofia, underscored the importance of the region’s well-educated workforce and the ongoing collaboration with Sofia Airport as key drivers of continued growth.
Challenges and Competitive Dynamics
Despite the promising outlook, the sector faces notable challenges. The surge in engine deliveries and the drive for modernization necessitate substantial investments in upgrading MRO networks and infrastructure. Additionally, the market is responding to increased demands for aviation safety and regulatory compliance, which require advanced communication systems and enhanced pre-flight inspection services.
Competitors in the region are adopting strategic measures to strengthen their positions. FL Technics is pursuing the acquisition of a Czech MRO provider, while Lufthansa has invested in AirBaltic to bolster its regional footprint. These developments reflect a broader trend of consolidation through acquisitions and partnerships aimed at expanding market share and improving service capabilities.
As Sofia Airport advances with the construction of a new 20-million-passenger terminal—the largest in the Balkans—and adapts its infrastructure to accommodate future growth, the MRO sector in the Baltics and Eastern Europe is set to play a crucial role in shaping the future landscape of European aviation.
