AerFin Reports Supply Crunch Extending Maintenance Cycles
A shortage of high-pressure turbine (HPT) blades has become the biggest constraint on CFM International CFM56 engine overhauls, according to AerFin. The supply crunch is extending maintenance cycles, increasing demand for spare engines, and reshaping how airlines manage shop visits. While production is gradually improving, the imbalance between demand and available material remains significant, with used serviceable material supplies also tightening.
