ATR and Pratt & Whitney Canada have concluded an agreement to ensure the PW127-series engines powering the airframer’s twin-turboprop range are able to use 100% sustainable aviation fuel (SAF) by 2025.

Toulouse-headquartered ATR says it aims to achieve certification for 100% SAF use on its ATR 42 and 72 aircraft by that year.

The agreement includes the PW127XT family, which entered service in November last year on an ATR 72-600 for Air Corsica.

ATR and P&WC have already laid some of the groundwork required for the approval, in June 2022 conducting a test flight in collaboration with Swedish carrier Braathens Regional Airlines of an ATR 72-600 with both its PW127M engines powered by 100% SAF.

“While all Pratt & Whitney Canada engines have already been certified for 50% SAF blends for more than a decade, ensuring readiness to operate with 100% SAF in future will allow us to maximise their potential for decarbonisation,” says Anthony Rossi, the engine manufacturer’s vice-president of sales and marketing.
