Next-gen engine TATs exceed 180 days with 21%+ shop visit cost overruns

Engine overhaul turnaround times have stretched to 180–200+ days, with over half of operators expecting no improvement for at least three years. Two-thirds of MRO operators report that shop visit costs for next-generation narrowbody engines exceed initial budgets by more than 21%, while a quarter experience overruns topping 50%. This is driven by persistent durability issues on next-gen engines and a high concentration of MRO spend on powerplants.
