Pratt & Whitney is looking for another 30% bump in PW1100 geared turbofan maintenance output this year as it seeks to return the engine fleet to the air.

Chris Calio, president of Pratt parent RTX, noted improvements in some key areas of the supply chain, such as higher production of structural castings and isothermal forgings, but stressed that more progress would be needed at pinch points to ensure maintenance and production goals were met.

“We saw some very good progress last year,” he said. “PW1100 [maintenance] output was up 30% last year. So very good progress in terms of material flow and in-shop performance. But we need to continue to ramp output to bend the curve here as we work our way through 2025.”

Pratt & Whitney’s commercial aftermarket sales were up 17% in the fourth quarter of 2024, driven by higher volumes in large commercial engines. This included about 800 shop visits for the V2500—a number the OEM expects to repeat this year.

“Retirements are very low and we expect that to continue as well for the next several years at least,” said Chief Financial Officer Neil Mitchill, who also highlighted the potential for sustained, high work scope overhaul demand. “We're getting good content on those shop visits because 20% of those engines haven't seen their first shop visit yet and only 55% have seen one. So, we've got plenty of tailwind in the installed base of both of those businesses looking over the next five years.”

RTX expects its commercial aftermarket sales to rise by low double digits this year. It also expects powder metal compensation impacts to be between $1.1-1.3 billion.
