United Airlines has selected MTU Aero Engines to maintain General Electric GE90-115B engines powering a fleet of Boeing 777-300ERs.
MTU says that the 12-year, hour-based agreement covers MRO services – including proprietary repairs by the German company – and engine trend monitoring for 49 powerplants.
Shop visits will be completed at MTU's Hannover facility, the only site in the company's network capable of overhauling GE90s.
Cirium's Fleets Analyzer shows that United has 18 777-300ERs in service and orders for another four of the type.
United's fleet also includes 55 777-200ERs and 19 777-200s. Some 20 777-200ERs are powered by GE90s, while the remainder of United's 777-200 series fleet are equipped with Pratt & Whitney PW4000s.
MTU chief programme officer Michael Schreyogg describes the deal as a "clear signal that we are expanding and deepening our support of United Airlines' fleet".
