MTU Maintenance reported an 18% increase in revenues in 2025 compared with the previous year, driven by strong demand for maintenance, repair and overhaul (MRO) services across its global network.
The company said MRO generated just over €6 billion in revenues for the MTU group during the year, with growth recorded across all market segments.
In total, the MTU Maintenance network, which includes joint venture EME Aero in Poland, processed around 1,500 engines in 2025, making it the world’s second-largest MRO service provider.
Pratt & Whitney’s GTF engines accounted for the largest share of shop visits, representing one-third of the total volume. This was followed by the IAE V2500 at 25% and CFM International’s CFM56 at 14%, with the remaining work spread across widebody, regional, business and industrial gas turbine engine portfolios.
“The MTU Maintenance network has yet again posted record results and is positioned for growth,” said Ottmar Pfänder, who assumed the Chief Program Officer role at MTU Aero Engines at the start of 2026.
The global MTU Maintenance workforce has expanded to more than 7,000 engine specialists across five continents.
Pfänder added: “From improved turnaround times to additional engine programs and capacity expansions, 2025 was a cornerstone year for the growth that we are expecting in the coming years. One thing I can say with certainty is that we don’t shy away from any challenges and that MTU’s engine experts are all-in when it comes to setting up the network for future success.”
The company also continued to invest in expanding its MRO capabilities and capacity across its global network.
MTU Maintenance Fort Worth is transitioning into a disassembly, assembly and testing (DAT) facility and will add MRO capability for CFM International’s LEAP engines and GE Aerospace’s GEnx engines. The first induction of the LEAP-1B engine variant is scheduled for mid-2026.
In Germany, MTU Maintenance Berlin-Brandenburg expanded its PW800 engine programme from a low-pressure turbine focus to full engine MRO capability. The Ludwigsfelde site is also increasing capacity in its industrial gas turbine segment and constructing a new production facility aimed at supporting a planned 30% increase in shop-visit volume in the coming years.
Elsewhere in the network, EME Aero inducted its 1,000th GTF engine in 2025 and opened a second test cell at its Jasionka facility in Poland. The joint venture expects to reach an operating volume of 500 shop visits per year by 2028.
In Asia-Pacific, MTU Maintenance Zhuhai opened a secondary production facility in nearby Jinwan to support the PW1100G-JM programme. Once fully ramped up, the two sites are expected to have a combined annual capacity of more than 700 shop visits.
MTU also reported growth in its ancillary services operations. The ON-SITEPlus service network attended more than 1,000 events in 2025, while MTU Maintenance Lease Services recorded over 90 transactions and expanded its lease pool to 140 engine and module assets.
Lease Services also grew its operations by 20% during the year and completed the rollout of its global parts supply network with a third warehouse in Zhuhai, complementing facilities in the Americas and Europe.
