Ryanair and CFM signed a Memorandum of Understanding (MoU) for a multi-year, multi-billion-dollar engine material services agreement under which CFM will support Ryanair's engine maintenance programme, which is expected to include the opening of 2 engine MRO Shops, which Ryanair will open from 2029 to support its fleet of almost 2,000 B737 engines. This multi-year agreement means that Ryanair has committed to purchase all its engine spare parts directly from CFM in a contract to support Ryanair's fleet as it grows to 800 Boeing 737 family aircraft, and over 2,000 CFM engines. The contract will support Ryanair's existing & future CFM56-7B and LEAP-1B engines, which are fitted to the airlines Boeing 737 NG and MAX aircraft, and Ryanair expects to take over the maintenance of these engines directly from CFM when it opens 2 engine MRO Shops in Europe towards the end of this decade.

Across the term, Ryanair expects to commit to purchasing spare parts in excess of $1 billion p.a. directly from CFM.
