CFM International has signed up four aircraft leasing companies to exclusively use its parts and repairs for their engine fleets.
International Lease Finance (ILFC), CIT, AerSale and the leasing arm of its parent General Electric, GE Capital Aviation Services (GECAS), have inked agreements to include their CFM56 powerplants in the manufacturer's TRUEngine programme.
Participants in the scheme commit to employing only spare parts by the original equipment manufacturer (OEM) and repair processes, which have been developed by CFM or its partners.
This is to avoid the use of alternative equipment made by competitors under a parts manufacturing approval (PMA) agreement, or repairs from maintenance providers which developed the processes under a designated engineering representative (DER) approval.
Since the use of alternative material typically has an adverse effect on the asset value and marketability of the engine, leasing companies tend to be particularly interested in using OEM equipment.
CFM established the TRUEngine programme in 2008 and currently has around 6,990 engines enrolled.
Around 22,000 CFM56 engines have so far been delivered in total.
