Pratt & Whitney’s GTF engine achieves key FAA certification milestone for Airbus A321XLR

Pratt & Whitney, an RTX business, has secured FAA certification for the PW1100G-JM engine to power the Airbus A321XLR. This milestone marks another step forward for the GTF (Geared Turbofan) program, which has powered over 2,100 aircraft since 2016. The A321XLR, expected to enter service in 2025, boasts extended range and payload capabilities, making it ideal for transatlantic routes traditionally serviced by wide-body jets and is sometimes categorized as a 757 replacement. Delta, among others, isn’t so sure.

Despite the engine’s impressive fuel efficiency—offering 20 percent savings over prior-generation engines—Pratt & Whitney has faced ongoing challenges with the GTF. In July 2023, RTX disclosed that contaminated powdered metal used in manufacturing certain engine parts could lead to cracks, necessitating inspections and grounding of numerous Airbus A320neo family aircraft. This issue has affected over 40 airlines globally, including US carriers such as Spirit Airlines and JetBlue.

RTX is addressing these concerns through enhancements in the GTF Advantage model, expected to deliver up to 1 percent better fuel efficiency and 4 to 8 percent higher thrust. The A321XLR has already garnered interest from 13 global customers for 217 aircraft. Its integration with the upgraded GTF Advantage could help secure its position as a critical solution for airlines navigating high fuel costs and stringent emissions regulations.
