If your aircraft wasn’t among the first wave of Cessna and Piper models approved for installation under EAA’s Dynon STC, we have great news: EAA just received an expanded Approved Model List (AML) from the FAA.
The aircraft models that may now have a Dynon EFIS installed are:
Beechcraft Bonanza / Debonair
Beechcraft Musketeer / Sundowner / Sierra
Cessna 150/152 - Commuter / Commuter II / Aerobat
Cessna 172 - Skyhawk
Cessna 175 - Skylark
Cessna 177 - Cardinal
Cessna 182 - Skylane
Cessna 205 / 206 / 207
Grumman AA-1/AA-5 - Yankee / Tiger
Piper PA-24 - Comanche
Piper PA-32 - Cherokee Six / Lance / Saratoga
Piper PA-28 - Cherokee / Warrior / Archer / Dakota
Piper PA-38 - Tomahawk
To confirm that your particular aircraft model and type certificate is eligible, check the EAA STC Approved Model List.
EFIS-D10A / EFIS-D100 Allowed as Backup Attitude IndicatorIn addition to the updated AML, the STC’s instructions for continued airworthiness have been updated to clarify that the Dynon EFIS-D10A or EFIS-D100 may be used either as primary instrumentation or as a backup. This can allow pilots of aircraft where a specific primary attitude indicator is needed for other systems - such as autopilot - to still install a Dynon EFIS as a backup.
For more information on this and other installation scenarios, see the full list of Frequently Asked Questions on the Dynon website.
