Airworthiness Directives; Garmin International GMN-00962 GTS Processor Units (GTS 825, GTS 855, GTS 8000)

FAA / Federal Register · 2020-27324

The FAA proposes to adopt a new airworthiness directive (AD) for certain Garmin International (Garmin) GMN-00962 GTS processor units (GTS 825, GTS 855, GTS 8000). This proposed AD was prompted by reports of GTS processor units issuing resolution advisories (RAs) when no risk of collision or loss of separation exists between the airplanes involved. This proposed AD would require updating the software version of the affected GTS Processor units. The FAA is proposing this AD to address the unsafe condition on these products.
