Lycoming Authorized Service Centers have been appointed the sole installers for Lycoming’s newest Echelon Supplemental Type Certificate (STC), which covers the Mooney M20E, M20F and M20J.

Mooney owners will be able to able to choose from among nearly 50 Authorized Service Centers to upgrade their engines to the more powerful, more efficient IO-390-A3A6, company officials said.

Lycoming began authorizing service centers in July, in part to provide a higher level of aftermarket support to legacy engines and aircraft, company officials said. To apply for Authorized Service Center (ASC) designation, facilities must meet specified equipment and facility requirements, maintain required staff training levels, meet or exceed required levels of quality and professionalism, and be capable of handling fly-in customers.

The STC includes 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.
