Aerospace Boosts CFM56 Turbine Blade Manufacturing

Aerospace is investing $33 million in its turbine blade manufacturing facility in Greenville, South Carolina, with about half of the funding focused on introducing newer manufacturing technologies for CFM56 high-pressure turbine (HPT) blades. The upgrades will support blades used in the CFM56 Performance Improvement Program (PIP) variants and include advanced grinding, laser drilling, and improved machining processes. These technologies are similar to those already used for LEAP engine blade production at the same facility and are intended to help meet strong demand for CFM56 maintenance. The demand is driven by high passenger traffic and delays in new aircraft deliveries, which increase the need for shop engine visits. Turbine blade availability has become a key factor affecting maintenance turnaround times. The Greenville site is the only facility producing CFM56 HPT blades, making the investment important for maintaining supply. The project is part of GE Aerospace’s broader $1 billion investment across U.S. facilities, which also includes about $200 million to expand manufacturing for LEAP engine durability kits and reverse bleed systems. These upgrades aim to improve engine reliability and are already in production for some Airbus A320neo engines, with similar solutions expected for Boeing 737 MAX LEAP-1B engines later this year.
