Turbofan Staple Of 737 Classic Fleets

Pratt & Whitney recently received the remaining three Federal Aviation Administration Supplemental Type Certificates (STC) approvals, certifying Global Material Solutions life-limited parts for the CFM56-3 engine high-pressure compressor, high- pressure turbine, and low-pressure turbine.

GMS has certified a total of 19 CFM56-3 engine life limited parts. Each part is certified with FAA Chapter 5 life limits equal to the original type certificate holder.

The FAA's STC process requires an applicant to meet all regulations required of a type certificate holder. The three Supplemental Type Certificates (STCs) come less than two months after the program's initial STC approval for the engine fan and booster. The initial Global Material Solutions STC approval was the first FAA certification granted for alternative life limited engine parts.

"Pratt & Whitney now has four STC approvals certifying all 19 life limited parts for the CFM56-3 engine. These STC approvals are a significant achievement," said Matthew Bromberg, vice president and general manager, Global Material Solutions. "We will now focus on leveraging Pratt & Whitney's OEM capability and quality to meet customer demand."

Global Material Solutions, which was publicly launched in February 2006, is an initiative delivering Pratt & Whitney OEM-quality life-limited and gas-path parts for the CFM56-3 engine at a competitive price. All Global Materials Solutions parts are expected to enter service later this year.
