Air Carrier Maintenance Programs
This advisory circular (AC) explains what the term "maintenance program" means. Our explanation describes the scope and content of air carrier aircraft maintenance programs. This is important as there is a significant difference between an air carrier maintenance program and an inspection program used in non-air carrier maintenance operations. We explain the background of these programs as well as the Federal Aviation Administration’s (FAA) regulatory requirements. We also describe and explain each of the 10 elements of air carrier maintenance programs. When we use "must" or "will" in this AC, we are referencing actual regulatory requirements. When we use "we," "us," or "our" in this AC, we mean the FAA. When we use "you," "your," or "yours," we mean you, the air carrier. When we use the term "person," it has the same meaning as that in Title 14 of the Code of Federal Regulations (14 CFR) part 1, § 1.1. |
