More Aircraft Types Approved for Dynon STC

January 12, 2017 - A long-anticipated expansion of the approved model list (AML) for EAA’s Accessible Safety STC to install the Dynon EFIS-D10A and EFIS-D100 flight displays has been granted by the FAA. The AML now includes the following type series:

Beechcraft Bonanza/Debonair Cessna 175 Maule M-4/5/6/7
Beechcraft Musketeer/Sundowner/Sierra Cessna 177/177RG Mooney M20
Beechcraft Skipper Cessna 182 Piper PA-24
Cessna 150 Cessna 180/185 Piper PA-28
Cessna 152 Cessna 205/206/207 Piper PA-32
Cessna 170 Cessna 210 Piper PA-38
Cessna 172 Grumman AA-1/AA-5

EAA STC, LLC., EAA’s subsidiary for STC development, will immediately begin taking orders for all listed types. The STCs sell for $100 to EAA members and allow for the installation of the Dynon unit as either a primary or backup attitude indicator in eligible aircraft. The display is connected to the aircraft’s pitot-static system and it will back up all primary flight instrumentation. A magnetometer, outside air temperature probe, and angle of attack probe are optional peripherals that expand the system’s functionality.

The STC’s instructions for continued airworthiness have also been updated to clarify that the Dynon unit may be used either as primary instrumentation or as a backup.

“We would like to thank our FAA oversight at the Chicago Aircraft Certification Office for working with us on our request to add more types to the approved model list,” said Sean Elliott, EAA vice president of advocacy and safety. “We have already begun developing the list for the next round of expansion.”

EAA is currently working on autopilot approvals and is actively pursuing approvals for TruTrak’s and Dynon’s autopilot systems. EAA is also advising an independent group working to certify the Trio Pro Pilot autopilot system in type-certificated aircraft.

“EAA will continue to push for an appropriate framework that manufacturers may use to certify all manner of low-cost, modern equipment that will enhance the safety and utility of the legacy fleet,” Elliott said. “We’re not done yet.”
