Regional Turboprop Engines Reduce Fuel Use by 25% to 40% on Short Routes
Pratt & Whitney Canada and Emerald Airlines Forge Long-Term MRO Partnership
At the Farnborough International Airshow, Pratt & Whitney Canada announced a nearly five-year agreement with Emerald Airlines to provide comprehensive maintenance, repair, and overhaul (MRO) services for the PW127M engines that power the ATR 72-600 regional turboprop fleet. The contract, extending through 2030, is designed to enhance Emerald Airlines’ regional operations and reflects a broader industry emphasis on improving fuel efficiency for short-haul flights.
Pratt & Whitney, a division of RTX (NYSE: RTX), will primarily deliver tailored MRO support from its Singapore facility, a global centre for turboprop engine services, with additional assistance from its Montreal site. Anthony Rossi, vice president at Pratt & Whitney Canada, highlighted the collaborative nature of the agreement, stating that the company worked closely with Emerald Airlines to develop a customized solution aimed at optimising engine maintenance costs, ensuring reliable performance, and maintaining dispatch availability. He emphasized that the deal underscores Pratt & Whitney’s commitment to expanding its MRO capabilities in tandem with customer growth.
Emerald Airlines, the exclusive operator of the Aer Lingus Regional network, welcomed the long-term certainty provided by the agreement. Richard Spencer, Chief Operating Officer at Emerald Airlines, described the MRO programme as delivering “real peace of mind,” with predictable costs that enable confident operational planning. He also noted that the arrangement aligns with the expectations of aircraft lessors by balancing performance, reliability, and asset value over time.
Fuel Efficiency and Sustainability Benefits of PW127M Engines
The PW100 engine family, which includes the PW127M, is widely recognised for its fuel efficiency on routes of 350 miles or less. Pratt & Whitney reports that these turboprop engines reduce fuel consumption by 25% to 40% compared to similarly sized regional jets, leading to proportional reductions in CO2 emissions. Furthermore, the engines are compatible with biofuels and certified to operate with blends containing up to 50% synthetic aviation fuel, supporting airlines’ sustainability objectives.
Despite these advantages, airlines may face significant upfront costs when retrofitting existing fleets or investing in new turboprop engines to realise these fuel savings. Nevertheless, industry analysts anticipate growing interest from carriers operating short-haul routes, where fuel efficiency is a critical factor in operational economics. This trend is expected to prompt competing engine manufacturers to accelerate improvements in their turboprop offerings, potentially intensifying competition and driving further innovation within the sector.
Industry Context and Company Profiles
Pratt & Whitney, with a heritage dating back to 1925, supports more than 90,000 in-service engines worldwide through its extensive global MRO network. Its parent company, RTX, employs over 180,000 people globally and reported sales exceeding $88 billion in 2025.
Emerald Airlines, founded in 2021, operates routes connecting Ireland, the United Kingdom, and France. The airline has been recognised as Aviation Company of the Year and offers franchise operations, ACMI wet lease, and private charter services. It is positioned as a significant player in the evolving landscape of regional aviation.
