What regulatory part incorporates the ACS?

• A. 14 CFR Part 61
• B. 14 CFR Part 43
• C. 14 CFR Part 65
• D. 14 CFR Part 91

Answer: (A)

The Airman Certification Standards are integrated into the part of the regulations that governs how pilots and other airmen are certified and tested. That is 14 CFR Part 61. This part lays out who can be certified, what tests are required, and how those practical tests are conducted. The ACS defines the knowledge, risk-management, and skill criteria that examiners use to judge a pilot’s competence during those tests, so it sits inside the Part 61 certification framework. The other parts cover areas like maintenance or general operating rules, but they do not govern how airman certification standards are applied, which is why Part 61 is the correct reference.
