DAFMAN 91-223 AMC Sup — Aviation Safety Investigations And Reports

What changed in this edition

This document has been substantially revised and must be completely reviewed. Major changes were made to align guidance with the investigation reporting requirements in the AF Safety Automated System (AFSAS) https://afsas.safety.af.mil. Common core investigation requirements have been moved to DAFI 91-204. All references to the terms “formal report(s), formal safety report(s), and safety investigation report(s)” have been replaced with the term “safety report(s)”. The use of “tab(s)” in safety investigation reporting have been replaced with “exhibit(s)”. (AMC) This supplement transfers AMC policy statements to the most recent publication of DAFMAN 91-223

Publications state their own changes on page 1 — behind a PDF the official host will not serve to a search engine. This is that section, verbatim. It describes the edition above, not every historical change.
