Business Fields & Segments

Business Segments

MTU Aero Engines' business activities are based on three pillars: the commercial business with the commercial OEM and spare parts businesses, the military engine business, and commercial maintenance, repair and overhaul (MRO) business. For the purposes of accounting, MTU's business activities are broken down into two segments: The first segment – the OEM (Original Equipment Manufacturing) business – comprises the commercial and military engine businesses, since they share the production, development, and miscellaneous other capacities. The second segment – the MRO (Maintenance, Repair and Overhaul) business – comprises MTU's commercial maintenance activities. The revenues are accounted for separately for each of the three main business units. All other financial key figures are shown for the two OEM and MRO business segments.

MRO Business


  • World's largest independent engine MRO provider (Maintenance, Repair and Overhaul) 
  • Exposure to highest growth engines (V2500, CFM56, CF34, GE90)
  • Strong presence in Asia

MTU Aero Engines' commercial maintenance, repair and overhaul activities are pooled under the roof of MTU Maintenance. The company operates locations in all major markets and is the world's largest independent provider of commercial MRO services. This market is also served by the OEMs and the airlines, alongside independent specialists the likes of MTU.

MTU Maintenance repairs engines manufactured under programs in which the company is a risk- and revenue-sharing partner. In addition, the Group also supports engines manufactured by other engine makers. MTU Maintenance thus offers a comprehensive range of services and full-package solutions for all major types of engines in virtually all thrust categories; in addition to aero engines, it also has industrial gas turbines in its portfolio.

In its MRO activities, MTU is committed to its motto that "Repair beats Replacement", restoring damaged parts wherever possible rather than replacing them with costly new parts. With the repair technologies it has developed in-house, the company achieves levels of restoration that are unique worldwide. Thus, for instance, MTU is capable of repairing even extremely heavily worn parts.

MTU Maintenance is well positioned for future growth. The repair portfolio comprises a large number of engine programs promising strong growth, such as the V2500 for the A320 family of aircraft, the CFM56, the GE90G and the CF34. MTU has established a strong foothold also in regional markets, having built a strong presence especially in Asia. Its excellent operational capabilities reflect in short turn-around times, high flexibility, and a sharp customer focus. The list of the company's MRO customers includes airlines around the globe.

OEM Business


  • Risk and revenue sharing partner with all major OEMs 
  • Focus on Low-Pressure Turbines and High-Pressure Compressors
  • Approximately 30 % of active aircraft with MTU participation

As part of its commercial activities, MTU Aero Engines designs, develops and manufactures engine modules and components. Its technological expertise in the field of low-pressure turbines and high-pressure compressors have made MTU a leading manufacturer of subsystems and components in the global engine business. Other players in this market, which is characterized by high market-entry barriers, are the Original Equipment Manufacturers (OEMs) and the component suppliers.

With its products, MTU has content on engines in all thrust and power categories, from powerplants for small business jets to the world's most powerful jetliners. The engine programs that currently yield the highest sales are the V2500, which powers the Airbus A320 family of aircraft, the GP7000 (A380),  the GENX (B787 / 747-8), as well as the PW2000 and CF6-80 for medium- and long-haul airlines. 

The company is a risk-and-revenue-sharing partner in the major commercial engine programs. Under the partnership arrangements, MTU assumes full development and production responsibility for the components and modules forming part of its work share. Typically, the program work share amounts to 10 to 20%, depending on the valuation of the module. MTU shares pro-rata in the revenues, in accordance with its work share. Its cooperation partners are the world's big-league players in the engine industry - Pratt & Whitney, GE, and Rolls-Royce.

To gird for the future, MTU has taken stakes in a number of significant engine programs and is well positioned in the marketplace. Among these future programs are the GP7000 for the Airbus A380 mega-liner and the GEnx engine to power the Boeing 787 Dreamliner and Boeing 747-8 long-range wide-body airliner. The advanced geared turbofan™ technology is applied in Pratt & Whitney's PurePower® engine family. To date, four major aircraft manufacturers have selected the GTFTM Engines to power their latest aircraft. Airbus is offering the GTF Engines for the A320neo and the A220. Mitsubishi has chosen the propulsion system as the sole engine choice for its MRJ regional jet. Irkut will equip its MC-21 with the engine. Last, but not least, Embraer has opted for the GTF Engines as the exclusive powerplant for its second-generation E-Jets.


  • Capability to develop and manufacture entire engines 
  • R&D is typically customer financed
  • MTU has high shares in key European military programs
