Federal Aviation Administration (FAA)-certificated pilot schools are regulated in accordance with Title 14 of the Code of Federal Regulations (14 CFR) part 141. Unlike pilot training conducted under 14 CFR part 61, part 141 pilot schools are required to use a structured training program and syllabus. Part 141 pilot schools may be able to provide a greater variety of training aids and require dedicated training facilities, flight instructor oversight, and FAA-approved course curricula. Colleges and universities, which may offer aviation degrees, often provide pilot training under part 141.
This advisory circular (AC) provides guidance for part 141 pilot school applicants and others interested in the certification standards and requirements for certification under part 141. This revision updates information found in AC 141-1A, Pilot School Certification, dated February 18, 1993, including additional information on compliance with part 141, and includes a chapter on Transportation Security Administration (TSA) requirements for part 141 pilot schools.

This order provides guidance and assigns responsibility for the implementation of the Aircraft Certification Service (AIR) certificate management (CM) of production activities of manufacturers and their suppliers producing products and articles in accordance with Title 14 of the Code of Federal Regulations. This order has been organized into three functional components. The first two chapters describe the CM process. Chapter 3 describes ongoing CM practices and includes Quality System Audits (QSA) and related activities. Chapters 4 and 5 describe additional CM activities, continuous improvement, and the Aircraft Certification Audit Information System’s (ACAIS) role in CM.

Purpose. This advisory circular (AC) describes an acceptable method, but not the only method, to support certain comparative assessment compliance findings to Title 14 of the Code of Federal Regulations (14 CFR) part 33, § 33.15, Materials, for turbine engine projects. Comparative assessment of certain data is often necessary to show the required functional and durability equivalencies between engine combustor and turbine section parts from different design or manufacturing processes, e.g., parts manufacturer approvals (PMA) versus type design parts. These equivalencies relate to oxidation, hot corrosion, and thermal fatigue and erosion characteristics in the engine environment. This data is necessary to support overall FAA design approval of turbine engine and auxiliary power unit (APU) parts approved under PMA, type certificate (TC) design change, supplemental type certificate (STC), or repair or alteration authority.
