On May 24, 2022, the FAA published an interim final rule that establishes new regulations for part 147. The new regulations can be found here: https://www.govinfo.gov/content/pkg/FR-2022-05-24/pdf/2022-10367.pdf
The final rule also includes some changes to part 65 regulations regarding certification of mechanics.
Specifically, on August 1, 2023, the FAA will begin testing mechanic applicants using the following standards:
One of the new subject areas in the Mechanic ACS is Human Factors. The Human Factors subject area is not currently included in the Mechanic Practical Test Standards or in 14 CFR part 147 appendices B, C, or D.
-
Aviation Maintenance Technician Schools (AMTS) must begin including human factors content that aligns with the Mechanic ACS, into their Aviation Maintenance Technician Schools (AMTS) curriculum by September 21, 2022 (the effective date of the part 147 interim final rule).
-
All mechanic applicants may be tested on the Human Factors subject area beginning on August 1, 2023.
Aviation Maintenance Technician Schools (AMTS) and individuals preparing for mechanic certification should have the knowledge and skills outlined in the mechanic ACS prior to taking any written, oral, or practical test administered by the FAA and its designees (to include knowledge testing centers and Designated Mechanic Examiners (DME’s)). The following resources can provide a variety of information regarding human factors in aviation maintenance.
FAA Resources:
- FAA Handbook, FAA-H-8083-30A, Aviation Maintenance Technician Handbook – General
