For those that have Garmin GSA-28 servos and may not be aware, a large percentage of the servos are eligible for replacement.

Here's a link to Garmin's service bulletin: https://support.garmin.com/en-US/aviati ... 7YNV5WnjA/

From the bulletin:

"Garmin has implemented several design and manufacturing process improvements to improve GSA 28 reliability. The latest update has been added to a consolidation of all past improvements into a single effort we are calling a GSA 28 Service-Life Extension Program. The Service-Life Extension Program allows up to five years to exchange, under warranty, all affected GSA 28 servos for servos marked with Mod 1.

All -00/-11 and all -20/-21 servos not marked with Mod 1 are eligible for exchange under this program.

-21 GSA 28 servos not marked with Mod 1 are eligible for exchange under this program."
