The Instructor may varythe depth and scope of the topics to be covered, depending on the type of airplane to be maintained and skills ofthe persons.ObjectivesAfter this module is complete the person is able to demonstrate the following skills:1. Demonstrate the procedure used to identify specific wire types using the airplane manuals.2. Know from approved data different insulation types and their relative qualities.3. Know the inspection criteria for wire and wire bundles.4. Know the standard installation practices for wire and wire bundles (airplane specific).5. Know typical damage that can be found (airplane specific).6. Demonstrate the repair procedures for typical damage found on the student’s type of airplane.7. Demonstrate the procedures to fitting differing types of sleeving (airplane specific).8. Know the procedures for termination and storage of unused wires.9. Demonstrate the correct installation practices for electrical bonds and grounds (airplane specific).StrategiesNormal classroom lecture is used for the majority of the training with hands-on practice for Section 6.Chapter 20 Wiring Practices, Wiring Diagram Manual and WDM Lists will be made available to the class so thathands-on use of the manual can be utilized so that wire identification, inspection, installation and repairprocedures can be fully explored. Examples of wire discrepancies will be made available to the student. TheATSRAC Task Group 1, Intrusive Inspection Final Report could be used to identify typical wire issues.MODULE E – WIRE1. Identification, type and constructiona. Wire type codes – alphanumericb. Wire type codes – specification and standard part numberc. Wire type codes – specified wire and alternated.
