Pratt & Whitney Canada and Leonardo have successfully completed the first flight for an AW139 helicopter powered by the PT6C-67C engine using 100% sustainable aviation fuel (SAF).
The 75-minute flight and ground tests that took place on November 21 at Leonardo’s facility in Cascina Costa di Samarate, Italy, evaluated engine performance at multiple power variations.
"Flights such as these are instrumental in our efforts to ensure 100% SAF compatibility for our engines," said Maria Della Posta, president, Pratt & Whitney Canada.
"This is the first time a PT6 engine has been flown using 100% SAF, marking this as a significant milestone for the unrivalled engine series. Proving the engine's capability with drop-in SAF provides the foundation for the future of the PT6 in sustainable aviation and builds on its legacy of success."
Ensuring compatibility with 100% SAF is part of Pratt & Whitney's strategy of enabling more sustainable aviation through the pursuit of smarter technologies, cleaner fuels, and greener business practices, supporting the aviation industry's goal of achieving net-zero CO2 emissions by 2050.
"The results of this first demonstration flight are a further testament to the outstanding design of the AW139, its high performance, and the excellent relationship we have with Pratt & Whitney Canada," said Gian Piero Cutillo, managing director, Leonardo Helicopters. "This flight demonstrates another tangible benefit of the most successful helicopter in its class and provides a positive way forward to the many operators carrying out missions in all weather conditions as they aim for more ambitious sustainability goals."
