Echelon STC for Mooneys certified

By Janice Wood · November 16, 2009 ·

Lycoming Engines recently received FAA Type and Production certification for its IO-390-A3A6 engine, followed by an FAA Supplemental Type Certificate (STC), the second STC earned as part of Lycoming’s Echelon STC program.

The IO-390-A3A6 provides more horsepower as well as improved climb and cruise performance, while maintaining the same footprint as the IO-360 engine, according to Lycoming officials. The STC covers replacing the original IO-360 Lycoming engine in the Mooney M20E, M20F and M20J with a new or remanufactured IO-390-A3A6 engine.

Like the first Echelon STC developed for the Cessna 177 RG Cardinal, this STC improves performance and adds value to the airframe, company officials claim.

The STC includes either a new or rebuilt IO-390-A3A6, Slick Start System and required documentation. In addition, Hartzell has certified both two-blade and three-blade propellers for the STC. It will be offered exclusively through Lycoming Authorized Service Centers.

For more information: 800-258-3279 or Lycoming.com.
