1.1 本规范规定了小型飞机设计载荷和条件的适航性要求。 1.2 本规范适用于F44术语标准中定义的小型飞机。本规范中使用了术语“飞机”，意思是“小型飞机” 1.3 设计批准申请人必须就本标准的使用向各自的CAA机构寻求个人指导，作为认证计划的一部分。有关CAA监管机构已接受本标准（全部或部分）作为遵守其小型飞机适航规则（以下简称“规则”）的手段的信息，请参阅ASTM F44网页（www。 ASTM.org/COMMITTEE/F44.htm），其中包括CAA网站链接。 1.4 单位-- 目前，国际单位制和英制混合使用。在许多地方，国际单位制已经包括在内，否则单位如14 CFR第23部分修正案62中所示。在未来的修订中，数值将始终以国际单位制表示，然后以方括号中的英制单位表示。每个系统中规定的值可能不是完全相等的；因此，每个系统应独立使用。将两个系统的值合并可能导致不符合标准。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 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 This specification addresses the airworthiness requirements for the design loads and conditions of small airplanes. 1.2 This specification is applicable to small airplanes as defined in the F44 terminology standard. Use of the term airplane is used throughout this specification and will mean “small airplane.” 1.3 The applicant for a design approval must seek individual guidance from their respective CAA body concerning the use of this standard as part of a certification plan. For information on which CAA regulatory bodies have accepted this standard (in whole or in part) as a means of compliance to their Small Airplane Airworthiness Rules (hereinafter referred to as “the Rules”), refer to ASTM F44 webpage (www.ASTM.org/COMMITTEE/F44.htm) which includes CAA website links. 1.4 Units— Currently there is a mix of SI and Imperial units. In many locations, SI units have been included otherwise units are as they appear in Amendment 62 of 14 CFR Part 23. In a future revision values will be consistently stated in SI units followed by Imperial units in square brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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.
