Chromalloy has received Federal Aviation Administration (FAA) Parts Manufacturer Approval (PMA) for its CFM56-5B/7B high pressure turbine (HPT) blade.
The Chromalloy HPT blade PMA is the only aftermarket alternative to the OEM-manufactured new part. The CFM56-5B engine powers the Airbus A320 family, while the Boeing 737NG uses the CFM56-7B engine.
Chromalloy now offers four PMA parts for the CFM56-5B/7B platform, including the HPT nozzle guide vane, the low-pressure turbine (LPT) stage 1 nozzle guide vane, and the HPT shroud.
The company's available repair solutions for the CFM56-5B/7B platform include over 50 designated engineering representative (DER) repairs, including 25 advanced repairs.
Chromalloy said it has been engaged with airline, leasing, and engine MRO shop customers with respect to its entire suite of CFM56 PMA solutions.
“Customers have been eagerly anticipating this FAA approval,” the company said. “Market demand has been strong, with the current backlog of orders expected to consume all of the production for the remainder of 2025.
“Many customers are seeking to reserve production slots into 2026.”
