AD 2024-14-03 GFC 500 Autopilot System

The FAA is adopting a new airworthiness directive (AD) for various airplanes modified with a certain configuration of the Garmin GFC 500 Autopilot System installed per Supplemental Type Certificate(STC) No. SA01866WI. This AD was prompted by a report of an un-commanded automatic pitch trim runaway when the autopilot was first engaged. This AD requires updating the applicable Garmin GFC500 Autopilot System software for your airplane and prohibits installing earlier versions of that software. The FAA is issuing this AD to address the unsafe conditions on these products.

This AD applies to all airplane models specified in Table 1 to paragraph (c) of this AD, having a Garmin GFC 500 Autopilot System that includes an optional GSA 28 pitch trim servo installed per Supplemental Type Certificate No. SA01866WI
