What the ACS says

Requirements for complying with ADs.

A sample oral question on this element

“What does complying with an applicable airworthiness directive require you to do?”

Study source: 14 CFR Part 39 and FAA-H-8083-30B, chapter 14 CFR Part 39; FAA-H-8083-30B Chapter 2, pages 14 CFR 39.11, 14 CFR 39.7, 2-8

If this code is on your test report

Your Airman Knowledge Test Report (AKTR) lists an ACS code for every knowledge area you missed on the written test. On the A&P oral, each of those codes adds one question to that section, on top of a minimum of four random questions (FAA Mechanic Test Generator FAQ). So if AM.II.D.K3 is on your AKTR, expect the examiner to ask about it. More on how codes turn into oral questions: A&P ACS codes: know your codes before the oral.
