Lists of Part 25/26 Rules and Their Associated Advisory Circulars and Policy Statements have been replaced by the search features in the FAA Dynamic Regulatory System (DRS). You can use DRS to search for Advisory Circulars (ACs) or Policy documents by the associated 14 CFR Part, or search a specific regulation to list documents applicable to that regulation.

DRS is continuously updated, and use of the system ensures that you are obtaining the most current possible information. It can be used to create a current list of Part 25/26 rules and associated guidance, which you can export to Excel to sort and cross-reference.

For a complete listing of all Part 25 and Part 26 guidance:

Advisory Circulars (ACs):

• Go to the Advisory Circulars category in DRS
• Under CFR Part Reference, select "Part 25" and "Part 26" and click Apply. When the results display, click the Save Results List button at the top of the results list to generate an Excel file with the search results.

 Policy documents:

• Go to the AVS/AIR Policy Statements, Memos and Deviations subcategory under the AVS/AIR Policy category in DRS
