1.1 本规程涵盖了对飞机系统和设备进行简化安全评估的方法。该材料是通过国际通用航空专家的公开共识开发的。该信息是通过关注采用传统系统的1级和2级普通类飞机而创建的。内容可能更广泛地适用。申请人有责任证明更广泛的适用性是一种具体的合规手段。如果认为本简化规程中规定的标准与特定应用无关，申请人应使用规程中定义的安全评估过程 F3230 本规程涵盖的主题包括:程序流程图、故障状态识别和分类、安全目标、设计和安装评估、故障状态的定性分析、共模分析、相似性的使用和文件。 1.2 打算将此信息作为设计批准的合规手段的申请人必须就其可接受的使用和应用向其各自的监督机构寻求指导（例如，适用的CAA发布的指导）。有关哪些监督机构已接受本标准（全部或部分）作为其监管要求（以下简称“规则”）的可接受合规手段的信息，请参阅ASTM委员会F44网页（www.ASTM.org/COMMITTE/F44.htm）。 1.3 单位-- 这种做法可能以国际单位制、英制工程单位或两者兼而有之的方式呈现信息；每个系统中所述的值可能不是完全等效的。每个系统应独立使用； 合并两个系统的值可能会导致不符合标准。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 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 practice covers methods for conducting a simplified safety assessment of aircraft systems and equipment. The material was developed through open consensus of international experts in general aviation. This information was created by focusing on Level 1 and Level 2 Normal Category aeroplanes employing conventional systems. The content may be more broadly applicable. It is the responsibility of the Applicant to substantiate broader applicability as a specific means of compliance. If the criteria specified within this simplified practice is deemed not to be relevant to a particular application, the Applicant should use the safety assessment process defined in Practice F3230 . The topics covered within this practice are: Procedural Flowchart, Failure Condition Identification and Classification, Safety Objectives, Design and Installation Appraisal, Qualitative Analysis of Failure Conditions, Common Mode Analysis, Use of Similarity, and Documentation. 1.2 An applicant intended to propose this information as Means of Compliance for a design approval must seek guidance from their respective oversight authority (for example, published guidance from applicable CAA) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this standard (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements (hereinafter “the Rules”), refer to the ASTM Committee F44 web page (www.astm.org/COMMITTEE/F44.htm). 1.3 Units— This practice may present information in SI units, English Engineering units, or both; the values stated in each system may not be exact equivalents. Each system shall be used independently of the other; combining values from the two systems may result in nonconformance with the standard. 1.4 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. 1.5 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.
