MTU Hannover MRO expansion targets late 2028 with 20%+ capacity

By Grace Kim

MTU Maintenance has begun construction on a more than €100 million expansion of its engine maintenance, repair and overhaul (MRO) site in Hannover, Germany, targeting a late-2028 opening and more than 20% additional capacity. The extension will add more than 10,000 square metres, equivalent to more than 107,600 square feet.

The project puts 7,700 square metres into production space and 2,200 square metres into office space. Those allocations represent 77% and 22% of the stated components, or 99% of the 10,000-square-metre minimum. MTU gives no baseline throughput, annual shop-visit volume or cost per visit, so the percentage cannot yet be translated into engines or aircraft supported annually.

MTU Aero Engines CEO Dr Johannes Bussmann said: “At MTU Aero Engines, we are prepared for growth in a strong and positive industry environment.” He also said MTU is investing at all its facilities in Germany and around the world to meet international demand for cutting-edge aero-engine technology and customers’ and partners’ MRO requirements for decades.

Those remain management expectations: the announcement offers no backlog, booked shop visits, delivery records or hiring timetable against which to test them. Until MTU supplies those figures, the growth statement remains intent rather than delivered capacity.

What will the new space do?

The extension will mainly host widebody engine shop visits and module repair, including work on next-generation GEnx and GE9X engines. MTU also plans to optimise some existing space for key engine repairs, which would spread work across upgraded and new areas.

No engine-type schedule, daily output target or staffing ramp accompanies the plan. The percentage therefore describes planned capacity, not opening-day availability.

MTU names five programmes serviced at the Hannover facility, spanning narrowbody and widebody engines:

• CF6-80C2
• GE90-110/-115B
• GEnx TCF
• PW1100G-JM
• V2500

It also operates as MTU’s centre for high-tech repairs, engine teardowns and on-site events. That gives the expansion an established operating base rather than a greenfield site, although the announcement offers no turnaround-time, module-repair or aircraft-on-ground improvement targets. More capacity may support more shop visits, yet neither pricing nor productivity appears in the release.

What is operating, and what remains promised?

MTU Maintenance Hannover is a fully owned subsidiary of MTU Aero Engines. Wirtschaftsförderungs-Gesellschaft Langenhagen Flughafen mbH partly supports the project, although MTU does not quantify that support. The announcement names no airline, lessor, regulator or external customer for the added capacity, and it provides no certificate numbers, approval dates or authority decisions.

MTU says Hannover already services the five listed engine programmes. Expanded GEnx and GE9X work inside the new extension depends on a facility that MTU targets to open in late 2028. No certification milestone, booked work or customer allocation is disclosed for that future scope.

The percentage is large; its precise meaning is not yet defined. For operators, current shop-visit services and future extension capacity are not interchangeable planning inputs.

The company anticipates around 200 new jobs to add to its skilled aviation maintenance technician workforce. That is a substantial staffing plan, but not evidence that the technicians or approved work packages will be ready for the targeted opening.

The more than €100 million commitment has moved beyond planning because construction has started. Its expected return, cost per shop visit and payback remain undisclosed.

Why does the network matter?

Jaap Beijer, Executive Vice President MRO Operations at MTU and managing director of the Hannover site, described Hannover as the birthplace of MTU’s MRO and said it had grown and developed over several decades. The site already supports five engine programmes and serves as MTU’s high-tech repair centre, so that description has an operating basis. He added:

“This new expansion is not just a building, it complements our existing expertise and ensures our key role within MTU’s maintenance network now and in the future. We are committed to the region, our workforce and our customers.”

The network case has a credible outline: more than 10,000 square metres, five listed engine programmes and an established repair centre could widen support for customer fleets. The test comes by late 2028, when the building, roughly 200 hires and widebody repair capability must be ready together. Until MTU publishes throughput, approvals and customer schedules, the added capacity remains a forecast, not a fleet-planning input.
