Definition
The section of the Code of Federal Regulations that sets the FAA's certification and operating rules for Aviation Maintenance Technician Schools (AMTS), including required curriculum subjects, minimum hours of instruction, instructor qualifications, facilities, equipment, and student testing standards.
Plain English
The federal rulebook that says what an aircraft mechanic school must teach, who can teach it, and what facilities and equipment the school must have to be approved by the FAA.
Context Anchor
Seen when reading about formal aviation maintenance training programs, school approval, and required courses of training.
Derivation
CFR stands for Code of Federal Regulations, the published collection of US government rules. Title 14 of the CFR covers Aeronautics and Space, and within Title 14 each numbered 'part' addresses a specific topic. Part 147 is the part dealing with aviation maintenance technician schools.
Why Pilots Care
Pilots themselves don't operate under part 147, but they rely on mechanics trained under it. Knowing the rule exists helps pilots understand why a certificated A&P mechanic has a defined, standardized training background.
Intuition Check
Do not read “part” as an aircraft part here. In 14 CFR part 147, “part” means a numbered section of federal rules.
Example Sentence 1
The school's airframe and powerplant curriculum was built to meet the subject and hour requirements of 14 CFR part 147.
Example Sentence 2
Instructors check that course content aligns with 14 CFR part 147 before starting a new class.
