EAA STC: A Breakthrough in Low-Cost Avionics

In April 2016, EAA, along with the FAA and Dynon Avionics, announced a breakthrough that will improve flight safety and reduce avionics upgrade costs for owners of certain type-certificated aircraft.
EAA now owns a supplemental type certificate (STC) that allows installation of the Dynon EFIS-D10A as a replacement for the airplane’s primary attitude indicator. This opens the door for innovations developed in the amateur-built and light-sport aircraft market to make their way into specific Cessna and Piper models.
