1.1 适用性: 1.1.1 本规范确定了经协商一致确定的行业标准，以证明符合普通类飞机的要求（“规则”）。 1.1.2 只有那些被认为足够成熟，可以普遍应用于认证项目，并且委员会一致同意向CAA提议接受的标准，作为遵守其规则的一种手段，才会被包括在内。 1.1.3 如果某一特定CAA的要求与其他CAA的规定不一致，则标准将包括不一致的要求以及标准中规定的适用性的一致要求。 1.1.4 除了确定F44委员会批准的标准外，本规范的结构遵循现有绩效/目标的结构- 尽可能接近普通类飞机的基本规则。然而，由于当局在构建规则时采用的差异，本规范的某些部分可能与特定当局的规则结构平行，但并非全部。其目的是以这样的方式构建本规范，即用户可以确定哪些标准适用于特定规则，规范处于最高级别，实践和测试方法处于下一级别。支持规范或实践的指南将处于其支持的下一个级别。 1.2 民航局: 1.2.1 CAA可以接受本规范的特定修订，作为其要求的可接受的合规手段（MoC）。作为民航局适航规则的MoC的接受和适用性仍然是各民航局的决定。CAA可以接受本规范，有或没有其规范验收文件中规定的限制。 有关哪些CAA已接受这些标准（全部或部分）作为其规则的可接受MoC的信息，请参阅ASTM F44网页（www.ASTM.org/COMMITTE/F44.htm），其中包括CAA网站链接。 1.3 申请人责任: 1.3.1 申请人必须就本规范和任何参考规范、实践、测试方法或指南的使用向各自的CAA寻求个人指导，以证明符合CAA规则。或者，申请人可以提出本规范中未包含的MoC，但他们有责任获得CAA对其提出的MoC的认可。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

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.
