Airport Compliance Application Suite (ACAS)

The Federal Aviation Administration’s (FAA) Airport Compliance Activity Suite (ACAS) consists of three sub-system enterprise-level applications used by Federal employees, contractors, and external airport entities to gather airport financial data using the Certification Activity Tracking System (CATS), and address compliance issues in the United States (U.S.) Airports using the Airport Compliance Division Compliance Database (ACODB) and provides a publicly accessible archive of the outcome of complaints filed against airports using the Part 16 Decision Database (Part 16). The ACAS system is authorized under 44 United States Code (U.S.C.) Sections 106(t), 3101, 40101, 42121, and 44701 Section 341, 510, 1210, Federal Aviation Reauthorization Act of 1996; Section 180, FAA Reauthorization Act of 2018. The FAA published this updated Privacy Impact Assessment (PIA) for ACAS in accordance with Section 208 of the E-Government Act of 2002 because a new application, Part 16 Case Management System (CMS), was added and to inform the public that the system is no longer a Privacy Act system of records and to update the System of Records Notices (SORN) section of the PIA. ACAS processes Personally Identifiable Information (PII) from members of the public, including public and private airports owners/airport employees, authorized airport representatives, sponsors, legal counsel, and complainants.
