Piper and DeltaHawk Explore Diesel Power for PA-44 Seminole

Piper Aircraft and DeltaHawk Engines have recently announced that they have entered into a Memorandum of Understanding (MOU). This marks the start of a collaborative effort to explore the possibility of integrating DeltaHawk's diesel engine into Piper's well-known PA-44 Seminole aircraft.

“We are thrilled to collaborate with Piper Aircraft on this exciting project,” said Christopher Ruud, CEO of DeltaHawk. “Our advanced Diesel engine technology has been developed to meet the evolving needs of the aviation industry, and we see tremendous potential in integrating it into Piper’s PA-44 Seminole. This partnership underscores our commitment to driving innovation and sustainability in aviation.”

The Memorandum of Understanding (MOU) details the plans for developing a Supplemental Type Certificate (STC) to install DeltaHawk's Diesel engine in both new and retrofitted Seminole aircraft. This partnership shows a commitment to exploring alternative propulsion solutions that provide improved efficiency, performance, and sustainability in general aviation.

“We are excited for this collaboration to install the DHK engine into the Seminole for many reasons, especially knowing the reliability of DeltaHawk’s engines,” said Marc Ouellet, VP of Engineering and Manufacturing at Piper Aircraft. “We are constantly seeking opportunities to innovate and advance our aircraft offerings. Working with DeltaHawk on this project aligns with our mission to explore cutting-edge technologies that can deliver significant benefits to our customers and the industry as a whole.”
