WIRING SYSTEMS LESSON PLANMODULE B: WIRING PRACTICES DOCUMENTATIONOverviewThrough Module B, the instructor lays the groundwork for safe effective maintenance and repair ofairplane wiring systems. The intent of this module is to teach the person how to locate desired information in theChapter 20 Wiring Systems overhaul manual, Wiring Diagram Manual and other applicable documentation. TheInstructor may vary the depth and scope of the topics to be covered, depending on the type of airplane to bemaintained and skills of the persons.ObjectivesAfter this module is complete the person is able to demonstrate the following skills:1. Know the applicable Sub-Chapters and Section to follow during normal and non -normal electricalmaintenance procedures.2. Demonstrate the use of the Cross-Reference Index, Chapter Table of Contents, and Subject Tablesof Contents so as to find specific material within each sub-chapter and section.3. Demonstrate the use of the associated tables for replacement of wire, connective devices andcontacts, and associated components, including approved replacements.4. Demonstrate the use of the Wiring Diagram Manual.5. Demonstrate the use of other Documentation (as applicable).StrategiesNormal classroom lecture is used for the majority of the training. The Chapter 20 Wiring PracticesManual, Wiring Diagram Manual, and other applicable documentation will be made available to the class so thathands-on exploration of the material can be achieved.MODULE B - WIRING PRACTICES DOCUMENTATION:1.
