介绍INTRODUCTION
The instructions in this manual tell how to do standard shop procedures during maintenance functions from simple checks and replacement to complete shop-type repair.
手册中的说明告诉我们如何在维修过程中进行标准的车间程序，从简单的检查和更换到完成车间式的维修。
If the component overhaul instructions are different from the data in this subject, use the component overhaul instructions.
如果部件大修说明与本手册的数据不同，请使用部件大修说明。
1. GENERAL 概述
A.The Boeing Standard Overhaul Practices Manual (SOPM), Document D6-51702, contains a Title Page, a Revision Record Page, a List of Effective Pages, a Table of Contents, and the individual standard overhaul practices manuals. These manuals are prepared by Boeing Commercial Airplanes Group.
波音SOPM，文件D6-51702，包含一页标题页、一个修订记录页、一份有效页清单、一个目录和相应的标准大修施工手册。这些手册由Boeing编写。
B.Each individual manual contains a Title Page, List of Effective Pages, Table of Contents, and the technical data for standard practices used during the overhaul of Boeing proprietary components. The technical data supplements data contained in the component-specific Boeing Commercial Jet Overhaul and Component Maintenance Manuals.
每本手册都包含一页标题页、一份有效页清单、目录和Boeing专有部件大修使用的标准施工的技术数据。技术数据的补充数据可以在有关部件的波音商业喷气式飞机大修和部件维护手册中查找到。
C.The technical data is collected from Boeing Process Specifications. Details are added or changed with service experience. The data is general. It is not about all situations or specific installations. Use it to help you write minimum standards.
技术数据是收集波音工艺规范形成的，并根据施工经验，增加或修改细节。数据是通用的，不能适用于所有情况或特定的安装，用它来帮助你编写最低标准。
D.Throughout the overhaul instructions, in the SOPM as well as in the component-related overhaul instructions, appears the phrase “standard industry practices.” This can be defined as follows:
在整个SOPM的大修说明和在相关部件大修说明中，都出现了“标准工业施工”这个词，它的定义如下：
(1)Those practices which are within the limits of “good engineering practice.”
施工在“良好工程施工”限制之内；
(2)Those practices which are typical of mechanics who have the necessary license(s) to do work on the airplane and its parts and related equipment.
施工是由持有必要的执照的机械员实施的，这个执照使其有资格在飞机及其部件和相关设备上进行工作；
(3)Those practices locally used by each operator, such as an airline or a repair facility, which are their usual procedures.
施工是每一家运营商，比如航空公司或修理厂做为其通用程序本地使用的；
(4)Those practices which are not new, special, or specified by the manufacturer.
这不指那些新的、特定的或厂家规定的施工。
2. MANUAL IDENTIFICATION 手册识别
A.We put the manuals into different groups because of the different types of data. Each manual has a special manual number.
由于不同的数据类型，我们将手册分成不同的组。每本手册都有一个特别指定的手册号。
B.Each manual number has six digits, in three two-digit parts.
每个手册号有6位数,由3个两位数组成。
(1)The first part is 20 as specified by Air Transport Association Specification 100 for standard practices.
按ATA 100规范规定，标准施工的手册号前两位是20。
(2)The second part is the section number, and puts the manuals into groups. Each group is about a different type of data, as follows:
第二部分是节号，并据此将手册分进不同的组。每组光宇一种不同的数据类型。如下：
(a)00 thru 09 is for introductory data
00到09是介绍性数据
(b)10 thru 19 is for repair and replacement procedures
10到19是修理和更换程序
(c)20 thru 29 is for inspection procedures
20到29是检查程序
(d)30 thru 39 is for cleaning procedures
30到39是清洁程序
(e)40 thru 49 is for finishing procedures
40到49是表面处理程序
(f)50 thru 59 is for installation procedures
50到59是安装程序
(g)60 thru 69 is for lists of specifications and materials
60到69是规范和材料清单
(h)70 thru 79 is for protection, packaging and storage procedures
70到79是保护，包装和储存程序
(3)The third part is assigned in numerical sequence. It identifies one individual manual; that is, all pages about a specified subject.
第三部分是按照数字顺序分配的。它识别一个单独的手册，也就是关于一个特定主题的所有页面。
3. LISTS OF EFFECTIVE PAGES 有效页清单
A.Each individual manual has a list of effective pages (LEP). The LEP is a list of all pages in that manual with the date of the latest revision to each page. This list will show if your copy of that manual contains the latest pages.
每本手册都有一个有效页清单（简称LEP）。LEP是手册中有最新改版的所有页的清单。这个清单表明你的手册是否包含了最新改版。
B.The SOPM Front Matter Introduction has a numerical index of the manuals in the SOPM, equivalent to a traditional Table of Contents, which gives the date of the latest revision for each individual manual, which will show if your copy of the LEP for a manual is up to date.
SOPM的前言介绍有一个SOPM手册的数字索引，等同于传统的目录，它给出了每本手册的最新改版数据，此处显示出手册的LEP是否是最新的。
C.The SOPM Front Matter Introduction LEP shows the latest date of the index pages, which will tell you if your copy of the Table of Contents is up to date.
SOPM前言介绍LEP指明索引页的最新数据，它告诉你你的手册的目录是否是最新的。
4. SOURCE DOCUMENT CROSS-REFERENCE 源文件交叉参考
A.Some of the manuals include procedures from Boeing Process Specifications and other source documents. Here is a list of these source documents and their equivalent SOPM subjects. This list does not include source documents which are only referenced in the manuals.
一些手册包括来自波音工艺规范和其他资源文件的程序。下面是这些源文件及其等效的SOPM主题的列表。此列表不包括仅在手册中引用的原始文件。
