Pratt & Whitney has today announced the introduction of GTF Hot Section Plus (HS+), an upgrade option for the PW1100G-JM engine that powers the Airbus A320neo Family, which will nearly double time on wing.

On Monday (June 16, 2025), from the Paris Air Show, Pratt & Whitney announced the introduction of Hot Section Plus (HS+), an upgrade option for the PW1100G-JM engine the powers the Airbus A320neo Family of aircraft. The Hot Section Plus upgrade has been derived from the GTF Advantage™ engine, which will offer twice the time on wing as today’s GTF™ engine, and will provide 90 to 95 percent of the GTF Advantage’s durability benefits. HS+ includes only around 35 part numbers and will be incorporated during PW1100G-JM engine maintenance. The option will be available for all customers to purchase, with installations starting ion 2026. GTF engines with the HS+ upgrade will be fully intermixable and interchangeable with both current GTF and GTF Advantage engine models.
In Monday’s announcement, Pratt & Whitney’s VP – Sales & Marketing, Nick Tomassetti, said,
“HS+ brings the durability improvements of the GTF Advantage hot section to today’s GTF engine. Customers operating the current GTF engine model will have the opportunity to nearly double time on wing.”
Pratt & Whitney’s GTF Advantage features the most advanced hot section in the single-aisle market. In the high-pressure turbine (HPT), the enhancements include a state-of-the-art airfoil design with improved coatings. The HPT and combustor also feature optimized cooling hole size, shape and location, with improved hole drilling techniques to reduce oxidation. The GTF engine is the most efficient engine available for single-aisle aircraft, delivering a fuel burn reduction of up to 20 percent compared to the prior generation of engines.
