This document announces termination of the Mode-S Traffic Information Service (TIS) at FAA terminal Mode-S radar sites. The FAA is replacing legacy terminal Mode-S radars via the Mode-S Beacon Replacement System (MSBRS) program, or may remove legacy terminal Mode-S radars as part of other ongoing activities. As each legacy terminal Mode-S Radar is replaced or removed, the FAA will no longer provide Mode-S TIS to capable transponders from that location. This change does not affect existing Traffic Information Service—Broadcast (TIS–B), Automatic Dependent Surveillance—Rebroadcast (ADS–R), or Automatic Dependent Surveillance—Same Link Rebroadcast (ADS–SLR) services currently provided to aircraft with a properly functioning Automatic Dependent Surveillance—Broadcast (ADS–B) system.

This notice provides information related to changes included in thenext phase of the Safety Assurance System (SAS). Deployment of SAS Phase 4 will occur inthree “rolling” waves. The project planning effort “rolls out” detailed plans for the foreseeablefuture and, as the project evolves, periodically reevaluates the completion dates and costs. Thisnotice will focus on information related to SAS Phase 4 Wave 1, which takes place from fiscalyear (FY) 2023 Quarter 3 to FY2025 Quarter 1.

This notice provides guidance to Federal Aviation Administration
(FAA) Flight Standards (FS) Safety Assurance offices concerning the changes to the certification
process of Title 14 of the Code of Federal Regulations (14 CFR) part 137 UAS. The FAA has
determined that part 137 UAS agricultural aircraft operations present a lower risk than other
certificated operations and revising the part 137 certification process would not adversely affect
safety. It is the intent of this notice to outline the changes to the certification process for UAS in
agricultural aircraft operations. This notice will help ensure uniform application of policy
through guidance.
