The first production Catalyst turboprop engines are currently under construction at GE Aerospace’s production facility in the Czech Republic, the company told AIN this week at NBAA-BACE 2025. GE’s first in this class—a 1,300-shp engine—obtained FAA certification in February. Meanwhile, Textron Aviation expects to receive FAA certification of its Denali, which will serve as the Catalyst’s launch platform, next year.

“Now we’re transitioning into production readiness, getting the supply chain in place, getting the service infrastructure in place so we can support our customer, Beechcraft Denali,” said Paul Corkery, the Catalyst general manager at GE Aerospace subsidiary Avio Aero.
