The FAA has issued a Supplemental Type Certificate for installation of the Trio Pro Pilot autopilot in all models of Cessna 172, 175, 177, 180, 182, 185, Piper PA-28, and Grumman AA-5.

All sales are subject to The STC Group LLC’s Limited Warranty. (See Warranty Tab.). If a deposit is made on a model with STC pending, deposit will be refundable until date of STC issuance

When ordering please provide your aircraft year, make, model, voltage, serial number, and N number.

It will help us expedite your order if you can verify that your aircraft was provisioned for a factory Navomatic autopilot when manufactured. Some aircraft came from the factory provisioned for a Navomatic autopilot, but no autopilot was installed.

If your Cessna 172 or 182 is equipped with a Cessna factory installed Navomatic autopilot or it was provisioned for a factory Navomatic autopilot, it will have an access panel installed in the right wing, at Wing Station 100.5.
