1.1 本规程涵盖了飞机电气布线系统的电气布线互连系统的基本检查程序。 1.2 本规程无意取代飞机或附件制造商或型式设计持有人发布的任何持续适航说明。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 本规程中使用的术语“电气系统”是指飞机上产生、分配和使用电能的部件，包括其支架和附件。 4.2 飞机的良好性能取决于电气系统的持续可靠性。 4.3 飞机上的电线或设备损坏，无论看起来有多轻微，都是不能容忍的。因此，重要的是使用最佳技术和实践来完成维护，以最大限度地减少故障的可能性。 4.4 在检查和评估EWI时，无论错误来源如何，都应纠正不正确的接线、布线或维修。 4.5 本规程无意取代或取代任何有关电气系统检查和维修的政府规范或特定制造商说明

1.1 This practice covers basic inspection procedures for electrical wiring interconnect systems for aircraft electrical wiring systems. 1.2 This practice is not intended to replace any instructions for continued airworthiness published by the aircraft or accessory manufacturer or type design holder. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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. ====== Significance And Use ====== 4.1 The term “electrical system” as used in this practice means those parts of the aircraft that generate, distribute, and use electrical energy, including their support and attachments. 4.2 The satisfactory performance of an aircraft is dependent upon the continued reliability of the electrical system. 4.3 Damaged wiring or equipment in an aircraft, regardless of how minor it may appear to be, cannot be tolerated. It is, therefore, important that maintenance be accomplished using the best techniques and practices to minimize the possibility of failure. 4.4 When inspecting and evaluating EWIS, improper wiring, routing, or repairs shall be corrected regardless of the origin of the error. 4.5 This practice is not intended to supersede or replace any government specification or specific manufacturer’s instruction regarding electrical system inspection and repair
