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.
|120-106A||AFS-300||Scope and Recommended Content for a Contractual Agreement Between an Air Carrier and a Maintenance Provider This revision of the advisory circular (AC) introduces new rulemaking regarding aircarrier contract maintenance programs and air carrier manual content pertaining to contract maintenance requirements and contract maintenance provider (MP) responsibilities required by Title 14 of the Code of Federal Regulations (14 CFR) part 121, §§ 121.368 and 121.369(b)(10), and part 135, §§ 135.426 and 135.427(b)(10). Additionally, this AC outlines the scope and recommended content requirements for contractual agreements between an air carrier and its contract MPs. It explains the background and the necessity to interject specific requirements into a contractual agreement to ensure the air carrier fully supports the requirements imposed by 14 CFR. Because the air carrier has the primary responsibility for the airworthiness of its aircraft, it must ensure the proper controls are in place to assess, qualify, and authorize work performed for it by other persons, regardless of whether a certificated or noncertificated MP performs the work.||01-04-2016|
