Chromalloy Receives FAA Approval for CFM56 High-Pressure Turbine Blade

Chromalloy Secures FAA Approval for CFM56 High-Pressure Turbine Blade
Chromalloy has obtained Federal Aviation Administration (FAA) Parts Manufacturer Approval (PMA) for its high-pressure turbine (HPT) blade designed for the widely used CFM56-5B and CFM56-7B engines. These engines power major commercial aircraft, including the Airbus A320 series and Boeing 737NG, respectively, representing a significant segment of the global commercial aviation fleet. This approval marks a pivotal achievement for Chromalloy, a leading aerospace aftermarket specialist.
Expanding Market Options with FAA-Approved Components
With this certification, Chromalloy’s HPT blade becomes the sole FAA-approved aftermarket alternative to the original equipment manufacturer’s (OEM) component. This development offers airlines, leasing companies, and maintenance, repair, and overhaul (MRO) providers a cost-effective and high-quality option for engine maintenance and repair. The new blade complements Chromalloy’s existing portfolio of PMA components for the CFM56 platform, which includes the HPT Nozzle Guide Vane, LPT Stage 1 Nozzle Guide Vane, and HPT Shroud. Additionally, the company provides over 50 designated engineering representative (DER) repairs for the CFM56 family, with 25 classified as advanced repairs that deliver enhanced value.
Demand for the newly approved turbine blade has been strong, with all planned production slots booked through the end of 2025. Customers are already securing manufacturing capacity into 2026, underscoring robust market confidence in Chromalloy’s technical capabilities and product reliability.
Challenges and Market Implications
As Chromalloy scales up production to meet growing demand, it faces challenges related to potential supply chain disruptions and the need to maintain regulatory compliance across multiple international jurisdictions. Ensuring consistent production quality will be essential as manufacturing volumes increase.
The FAA approval has been met with a positive market response, boosting investor confidence and opening the possibility for price adjustments as Chromalloy’s aftermarket products gain wider acceptance. Competitors are anticipated to respond by accelerating their own technological developments or pursuing strategic partnerships to strengthen their turbine blade offerings.
This latest FAA certification reinforces Chromalloy’s position as a key player in the engine aftermarket, providing airlines with reliable alternatives to OEM parts while maintaining rigorous standards of safety and performance.
