The advantage is
what you recover.
Expect approximately 35% savings on total CFM56 engine overhaul costs through broader in-house repair and greater recovery of your existing parts.
Savings depend on engine condition, repair eligibility and the agreed work scope, compared with a replacement-led approach.
When more of the material in your engine has an approved repair route, fewer parts need to be purchased as replacements. GTS connects those component decisions with the complete engine work scope.
