Description

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.
