A Major Leap for Regional Commercial-Aircraft: Pratt & Whitney Canada Delivers First Engines for D328eco

In a significant move for the future of regional air travel, RTX’s Pratt & Whitney Canada has delivered the first set of PW127XT-S development engines to Deutsche Aircraft. This delivery, announced on November 17, 2025, marks a critical milestone in the development of the D328eco, a next-generation regional turboprop designed to set new standards in efficiency and Sustainability. The engines were received at Deutsche Aircraft’s headquarters in Oberpfaffenhofen, Germany, and are slated to power the first D328eco test aircraft, signaling a tangible shift from the drawing board to the testing phase.

The partnership between Pratt & Whitney Canada, a global leader in aircraft propulsion, and Deutsche Aircraft, a German Manufacturers reviving the legacy of the Dornier 328, is built on a foundation of four decades of collaboration. This latest venture aims to address the growing demand for more sustainable and economically viable regional air transport. The D328eco program is not merely an update to an existing airframe; it represents a forward-looking approach to aviation, combining a proven aircraft design with cutting-edge engine technology to meet the challenges of the modern era.

As the aviation industry charts a course toward a greener future, the D328eco stands out. The choice of a turboprop platform is deliberate, as these aircraft are already significantly more fuel-efficient on shorter routes compared to regional jets. The integration of the highly advanced PW127XT-S engine, coupled with a joint commitment to enabling 100% Sustainable Aviation Fuel (SAF) capability, positions the D328eco as a compelling solution for operators looking to modernize their fleets while reducing their environmental footprint.

The Power Behind the Progress: The PW127XT-S Engine

A Legacy of Reliability and Innovation

The PW127XT-S is the latest evolution in Pratt & Whitney’s legendary PW100 engine family, a series that has been a workhorse in regional aviation for four decades. With over 208 million flying hours accumulated across the entire family, the PW100 series has a well-earned reputation for dependability. The PW127XT-S builds upon this legacy by incorporating the latest materials and technology to deliver measurable improvements in performance and operational efficiency.

For airline operators, the numbers speak for themselves. The engine provides a 3% improvement in specific fuel consumption, a crucial factor in managing operational costs and reducing emissions. Beyond fuel savings, the PW127XT-S is engineered for longevity and reduced maintenance. It offers a remarkable 40% increase in time on wing, meaning the aircraft spends more time generating revenue and less time in the hangar. Furthermore, maintenance costs are projected to be 20% lower, with only two scheduled engine events required over a ten-year period. These advancements directly translate to a more robust and predictable operation for regional carriers.

The collaboration is focused on integrating this advanced propulsion system seamlessly with the D328eco airframe. The goal is to create a synergistic platform where both the engine and the aircraft design work in concert to maximize performance. This holistic approach ensures that the final product is not just a collection of advanced parts, but a highly optimized and competitive aircraft for the regional market.

“The PW127XT-S builds on our decades of experience in turboprop propulsion and incorporates the latest innovations to enable industry-leading fuel efficiency and time on wing. Our ongoing collaboration with Deutsche Aircraft to combine our dependable propulsion technology with the innovative design of the D328eco will deliver a highly compelling aircraft for future operators.” – Scott McElvaine, Vice President, Sales and Marketing, Pratt & Whitney Canada

Charting a Course to 100% SAF

A cornerstone of the Partnerships between Pratt & Whitney Canada and Deutsche Aircraft is a shared commitment to sustainability. A key objective of the D328eco program is to ensure the PW127XT-S engine is capable of running on 100% Sustainable Aviation Fuel (SAF). This includes advanced biofuels and hydrogen-based Power-to-Liquid (PtL) fuels, which are seen as critical components in the industry’s long-term decarbonization strategy.

This focus on SAF compatibility is not just an aspiration; it’s an active area of collaboration. Both companies are working to test and validate the engine’s performance with various synthetic fuels to ensure the D328eco is ready for the future fuel landscape. By designing for 100% SAF from the outset, the aircraft will offer operators a “drop-in” solution that aligns with evolving environmental regulations and corporate responsibility goals, providing a clear path to reducing net carbon emissions.

The selection of a turboprop engine is itself a significant step toward sustainability. On regional routes of up to 400 nautical miles, modern turboprops already consume around 40% less fuel and produce 40% fewer CO2 emissions than many regional jets performing the same mission. By further enhancing this inherent efficiency with the PW127XT-S and preparing it for SAF, the D328eco is poised to become one of the most eco-friendly aircraft in its class.

The D328eco: Redefining Regional Air Transport

Building on a Proven Platform

The D328eco is engineered to be a versatile and modern solution for regional Airlines. While it builds upon the robust and reliable heritage of the Dornier 328, it incorporates substantial upgrades that enhance its capabilities and appeal. The aircraft is designed to meet the evolving needs of regional markets, which demand greater capacity, lower operating costs, and improved passenger comfort.

One of the most significant enhancements is a 25% increase in passenger capacity compared to the original Dornier 328. This allows airlines to improve route economics and serve a wider range of markets. When combined with the efficiency of the PW127XT-S engines, the D328eco is expected to achieve up to 14% lower fuel consumption per seat than its predecessor. This dual benefit of higher capacity and lower fuel burn makes for a powerful economic argument for fleet renewal.

Deutsche Aircraft’s vision is to deliver a platform that offers long-term value. By focusing on a modern, fuel-efficient design, the company is providing a tool for airlines to operate profitably while navigating the transition to more sustainable operations. The aircraft’s versatility will enable it to serve a variety of regional routes, from short commuter hops to longer connections between secondary cities.

“With the improved performance of Pratt & Whitney Canada’s PW127XT-S engines, the D328eco will deliver a modern, versatile, and fuel-efficient solution for regional air transport. Collaborating with Pratt & Whitney Canada allows us to deliver the best propulsion technology for our aircraft, providing greater capacity, lowering operating costs, and driving long-term value for our customers.” – Nico Neumann, Chief Executive Officer, Deutsche Aircraft

From Concept to Reality

The delivery of the first PW127XT-S engines is a pivotal moment for the D328eco program. It marks the transition from years of design, planning, and collaboration into the crucial phase of ground and flight testing. These engines will be installed on the first test aircraft, known as TAC1, bringing the D328eco one step closer to its planned entry into service in 2027.

The journey to this point began with the formal selection of the PW127XT-S engine back in June 2022. That decision was followed by a collaboration agreement to pursue 100% SAF capability, underscoring the program’s sustainable ambitions from early on. The steady progress since then, culminating in the on-time delivery of the first development engines, demonstrates the strong alignment and commitment between the two partner companies.

This milestone is not just a technical achievement but also a signal of confidence in the regional aviation market. As the world continues to reconnect, efficient and sustainable regional aircraft will play a vital role in linking communities and economies. The D328eco program is on a clear trajectory to meet that demand with a product that is both technologically advanced and environmentally conscious.
