SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to Garmin GMN-00962 GTS processor units (GTS 825, GTS 855, GTS 8000) with part number 011-02571-0( ) and software version 3.13 or earlier (except version 3.12.1). The NPRM published in the Federal Register on December 14, 2020 (85 FR 80696). The NPRM was prompted by seven reports of false RAs involving aircraft equipped with Garmin GMN-00962 GTS processor configured for traffic collision avoidance system II (TCAS II) ( printed page 18888) (configuration marketed as GTS-8000 units). The Garmin GMN-00962 GTS processor units are marketed by Garmin as the GTS 825, GTS 855 or GTS 8000, with the marketing name representing the traffic system configuration. A false RA occurs when there is no risk of collision or loss of separation of the airplanes. These false RAs result from the GTS Processor software potentially calculating incorrect range rates. This results in traffic advisories or RAs being generated when targets are greater than 10 nautical mile…
