Operations Control Center (OCC) for Helicopter Air Ambulance (HAA) Operations
This advisory circular (AC) provides information and recommendations to assist helicopter air ambulance (HAA) operators with the development, implementation, and integration of an Operations Control Center (OCC). By requiring larger HAA operators (per Title 14 of the Code of Federal Regulations (14 CFR) part 135, § 135.619) and encouraging smaller HAA operators to implement OCCs and operational control procedures, the Federal Aviation Administration (FAA) intends to further increase HAA safety through the implementation of OCCs.
Best Practices for Engine Time In Service Interval Extensions
This advisory circular (AC) provides information on engine time in service interval extensions. The AC explains the background of engine time in service intervals as well as the Federal Aviation Administration’s (FAA) regulatory requirements for time limitations and time in service intervals for engine overhauls. The AC also provides aircraft operators with information on the best practices for an engine time in service interval extension program and how to obtain an engine time in service interval extension.
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|
