The Precision Quality Difference

Our radial engine overhaul process incorporate the most stringent standards in the industry. With an In-House Quality Assurance Program exceeding industry standards, superior technical personnel, state of the art test cell and excellent long-term operational history, Precision Engines LLC is committed to the highest quality of workmanship, service and reliability standards.

Our world-class and advanced quality systems carry these repair certifications: FAA, EASA, and ISO 9001:2008.

We build our engines to a Precision Specification. This “internal” specification complies with the Pratt & Whitney and Curtiss-Wright overhaul specification with one very important additional fact.

When we measure a part to put into an engine, we use the “tighter” clearance allowed by the manual. Other companies may use parts that are at the end of their life or at “maximum” allowed clearance. This means that the engine they build is built with parts that may exceed P&W and CW wear limits during the life of the engine. By using our Precision specification we assure reliability.

To backup our claims, we have the best warranty in the industry.
