CF6

Maintenance, Repair & Overhaul

CF6 (MRO)

MTU has been a risk-and-revenue sharing partner in this GE Aviation engine program since 1971, when the company produced the first parts for the CF6-50. In the meantime, MTU manufactures parts for the entire CF6 family (CF6-6, CF6-80A, -80C, -80E). The CF6 is a two-shaft turbofan which powers medium- to long-haul Airbus and Boeing wide-body aircraft.

For the CF6 MTU Aero Engines produces turbine and compressor parts. Having been manufactured for over 40 years, this engine now figures more and more importantly in MTU’s repair and spare parts business.
