Appendix 1 to AMC 20-29– Applicable CSs and Relevant Guidance

ED Decision 2010/003/R

1.         Applicable CSs. A list of applicable CS paragraphs is provided for subjects covered in this AMC (see notes). In most cases, these CS paragraphs apply regardless of the type of materials used in aircraft structures.

Notes:

(1)        This list may not be all inclusive and there may be differences between certification agencies (e.g. FAA and the Agency).

(2)        Special conditions may be issued in accordance with Part-21 21.A.16B for novel and unusual design features (e.g., new composite materials systems).

2.         Guidance

FAA issues guidance providing supportive information of showing compliance with regulatory requirements. Guidance may include the advisory circulars (AC) and policy statements (PS). In general, an AC presents information concerning acceptable means, but not the only means, of complying with regulations. The guidance listed below is deemed supportive to the purposes of this AMC. These FAA documents can be located via website:http://www.faa.gov/regulations_policies/. In addition, EUROCAE have developed industry standards that are recognised by the Agency.

Note: Many of the FAA documents are harmonised with EASA. Applicants should confirm with the Agency if in doubt regarding the status and acceptance of any such documents by the Agency.
