|135-7B||AFS-300||Part 135: Additional Maintenance Requirements for Aircraft Type Certificated for Nine or Less Passenger Seats This advisory circular (AC) provides information for establishing methods acceptable to the Administrator for compliance with the additional maintenance requirements of Title 14 of the Code of Federal Regulations (14 CFR) part 135, § 135.421 for certain air carriers and commercial operators. In addition, this AC provides information related to other regulatory maintenance requirements applicable to part 135 aircraft type certificated (TC) for nine or less passenger seats. This AC gives part 135 certificate holders an acceptable means to comply with the regulations; however, it is not the only means. This AC is not mandatory and does not constitute a regulation. When this AC uses mandatory language (e.g., “must” or “may not”) it is paraphrasing a regulatory requirement or prohibition. When this AC uses permissive language (e.g., “should” or “may”) it describes an acceptable means, but not the only means, for complying with regulations. If you use the methods described in this AC to comply with a regulatory requirement, you must follow them in all respects.||08-11-2016|
Standardized Procedures for Obtaining Approval of Data Used in the Performance of Major Repairs and Major Alterations
This advisory circular (AC) describes a standardized procedure for requesting approval of technical data associated with major repairs/major alterations.

This AC is not mandatory and does not constitute a regulation. This AC describes an acceptable means, but not the only means, to obtain approved data for a major repair or major alteration. However, if you—whether you’re an aircraft owner, operator, or Aviation Maintenance Technician (AMT), collectively termed an applicant—use the means described in the AC, you must follow it in all important respects.

|00-6B||AFS-400||Aviation Weather This advisory circular (AC) was published by the Federal Aviation Administration (FAA) Flight Standards Service (AFS), with contributions from the National Weather Service (NWS). The publication began in 1943 as CAA Bulletin No. 25, Meteorology for Pilots, which at the time contained weather knowledge considered essential for most pilots. As aircraft flew farther, faster, and higher, and as meteorological knowledge grew, the bulletin became obsolete. It was revised in 1954 under a new title, The Pilots’ Weather Handbook, and updated again in 1965. In 1975 it was revised under its current title.||08-23-2016|
