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 STC, LLC, a subsidiary of EAA, now owns a supplemental type certificate (STC) that allows installation of the Dynon EFIS-D10A or EFIS-D100 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. Currently, the Approved Model List (AML) includes the following aircraft series (including all variants on each type certificate):
Beechcraft Bonanza/Debonair, Beechcraft Musketeer/Sundowner/Sierra, Beechcraft Skipper
Cessna 150, Cessna 152, Cessna 170 Cessna 172, Cessna 175, Cessna 177, Cessna 177RG, Cessna 180/185, Cessna 182, Cessna 205/206/207, Cessna 210
Piper PA-24, Piper PA-28, Piper PA-32, Piper PA-38

Unique to this STC, EAA worked with the FAA to allow the Dynon EFIS-D10A or EFIS-D100 to be installed without the traditional technical standard order (TSO) or parts manufacturer approval (PMA) requirement. Dynon’s product is also verified against the recently developed ASTM 3153-15, Standard Specification for Verification of Avionics Systems. The Dynon unit was flight tested in Oshkosh earlier this year in EAA’s own Cessna 172M, with FAA observation.
The STC is available through EAA STC for $100 to EAA members.
