Engine Lease Finance (ELFC) has become the first CFM International (CFMI) spare-engine lessor to use the manufacturer’s portable maintenance for lessors (PML) program under a memorandum of understanding that could be formally ratified by year’s end. The scheme allows CFMI to provide engine maintenance, repair and overhaul services for leased fleets under PMLs that will be transferable between lessees, enabling them to more accurately predict maintenance costs, while permitting lessors to control such costs throughout the life of an aircraft, said CFMI.
