The ACRP Legal Research Digest 21: Compilation of DOT and FAA Airport Legal Determinations and Opinion Letters Through December 2012 is a compilation of FAA Part 16 decisions, DOT Part 302 decisions, and FAA legal opinion letters as of December 2012. FAA publishes Part 16 and Part 302 decisions online, but indexes them only by party name and docket number. ACRP LRD 21, which can be found online at https://crp.trb.org/acrplrd21/, indexes decisions by subject matter and is an extremely valuable research aid for airport operators, law firms, and consultants. It has been four years since the last compilation and the FAA has since issued significant compliance decisions over the last four years.

The objective of this research is to update ACRP LRD 21 update annually for four years.
