Scope 1.1 Applicability: 1.1.1 This specification identifies the industry standards that have been determined by consensus to demonstrate compliance to the requirements (“the Rules”) for Normal Category Aeroplanes. 1.1.2 Only standards that are considered mature enough for general application to certification projects and have been found acceptable by committee consensus to propose to the CAAs for acceptance as a Means of Compliance to their Rules are included. 1.1.3 In the event that a particular CAA’s requirements are not harmonized with the other CAA’s requirements, the standards will be written to include the non-harmonized requirements as well as the harmonized requirements with the applicability defined in the standard. 1.1.4 In addition to identifying the standards that have been approved by the F44 Committee, the structure of this specification follows the structure of the existing performance/objective-based rules for Normal Category aeroplanes as closely as practical. However, due to differences employed by the authorities in structuring the rules, some sections of this specification may parallel the structure of a particular authority’s rules, but not all. The intent was to structure this specification in such a way that the users could identify what standards would be applicable to specific rules with the specifications at the highest level and practices and test methods being at the next level down. Guides that support a specification or practice will be at the next level down from what they support. 1.2 Civil Aviation Authorities: 1.2.1 CAAs may accept a specific revision of this specification as an acceptable Means of Compliance (MoC) to their requirements. Acceptance and applicability as a MoC to the CAA’s airworthiness rules remains the decision of the respective CAAs. CAAs may accept this specification, with or without limitations as defined in their specification acceptance document. For information on which CAAs have accepted these standards (in whole or in part) as an acceptable MoC to their Rules, refer to the ASTM F44 webpage (www.astm.org/COMMITTEE/F44.htm) which includes CAA website links. 1.3 Applicant Responsibility: 1.3.1 The applicant must seek individual guidance from their respective CAA concerning the use of this specification and any referenced Specifications, Practices, Test Methods, or Guides to show compliance to the CAA rules. Alternatively, an applicant may propose a MoC other than those included in this specification but it is their responsibility to obtain acceptance of their proposed MoC from their CAA. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
