EAA, Dynon Expand STC Program For GA Aircraft


Four more aircraft makes are now approved for the EAA/Dynon avionics Supplemental Type Certificate program. Owners of some Beechcraft, Grumman, Maule and Mooney models can now purchase the STC and install the two Dynon electronic flight information systems, EAA announced this week. The EFIS-D10A and EFIS-D100, which have been made available in the past year for common Cessna and Piper airplanes, can be installed in models on the Approved Model List, which EAA says will continue to expand.

Under the Accessible Safety STC program, EAA members can purchase STCs for $100 and install the units as primary or backup attitude indicators, connecting them to the aircraft’s pitot-static system. This week’s announcement comes after the recent meeting of FAA and EAA officials in Oshkosh to discuss expanding on the FAA’s moves to allow non-certified, safety-enhancing equipment installations for certified aircraft.

The list of eligible aircraft now includes:

– Beechcraft Bonanza, Debonair, Musketeer, Sundowner, Sierra, and Skipper

Cessna 150, 152, 170, 172, 175, 177, 177RG, 180, 182, 185, 205, 206, 207, and 210

Grumman AA-1 and AA-5

Maule M-4, M-5, M-6, and M-7

Mooney M20

Piper PA-24, PA-28, PA-32, and PA-38

The Dynon units include the 4-inch EFIS-D10A primary flight display and 7-inch EFIS-D100, which come with battery backups and include options for additional flight information such as angle of attack, true airspeed and winds aloft.
