Durability Kit Clears Way For Engine Upgrades And Retrofits
GE Aerospace has announced that its CFM Leap 1B durability kit has received approval from the FAA, paving the way for installations during shop visits and on new-production engines in the coming months. The kit, which includes new turbine blades and nozzles, aims to address wear issues seen in hot, harsh operating environments. According to GE Aerospace CEO Larry Culp, the full rollout of the kit is expected in 2027, with fleet retrofits being a multi-year effort. This development was first reported by Aviation Week.
