U.S. airports that receive assistance from the federal government are required to comply with a number of obligations imposed by federal law.
The TRB Airport Cooperative Research Program's ACRP Web-Only Document 65: DOT and FAA Airport Legal Determination and Opinion Letter Abstracts of 2023 covers case-specific guidance from U.S. DOT or FAA on various federal airport compliance matters released since the previous update to ACRP Legal Research Digest 21.
This document is supplemental to ACRP Legal Research Digest 21: Compilation of DOT and FAA Airport Legal Determinations and Opinion Letters as of December 31, 2023, which contains agency determinations covering administrative cases brought against large and small airports throughout the United States, as well as DOT and FAA opinion letters, memoranda, and related documents. These documents cover legal matters that include reasonableness of contractual terms, leasing practices, airport rules and regulations, airport charges imposed on aeronautical users, including airlines, and the standards for determining airport sponsor compliance with other federal obligations.
