Dual Pac

Soloy Dual Pac – Twin Engine reliability with single propeller symmetry. The Dual-Pac was designed, patented and Certified by Soloy to safely combine the output of two independently operating Pratt Whitney PT6D-114A engines for a single propeller output. The system was developed with extreme redundancy so that single engine operation is not only safe, but able to be done intentionally under certain conditions.

The Dual-Pac was tested for thousands of hours under the harshest conditions and was certified under FAA STC # SE00482SE

During certification, the Dual-Pac was flown on a DeHaviland DHC3 test aircraft and on our own design Pathfinder 21 test aircraft.

The Dual Pac is available for designers of  new aircraft and for special projects requiring a fully certified twin-engine power plant.
