Piper Aircraft is exploring the US-built DeltaHawk diesel engine as a possible option for PA-44 Seminole new and legacy aircraft.
Piper announced overnight at Sun 'n' Fun in Lakeland, Florida, that they had signed an memorandum of understanding (MOU) with the Wisconsin-based engine manufacturer.
The MOU outlines the development of a Supplemental Type Certificate (STC) for installing DeltaHawk diesel engine into both new and retrofit Seminole aircraft.
According to Piper, the MOU is part of a program to explore alternative power sources for the twin trainer, which currently is fitted with avgas-burning Lycoming IO-360 engines.
"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."
Marc Ouellet, Piper VP of Engineering and Manufacturing, said that the project could provide a technological step-change for the PA-44 airframe.
"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," he said.
"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."
