What are Electrical Wiring Interconnection Systems?

EWIS stands for Electrical Wiring Interconnection System, and in the context of aviation, it refers to a set of regulations and guidelines that govern the design, installation, inspection, and maintenance of electrical wiring systems in aircraft. The purpose of EWIS is to ensure the continued safe operation of an aircraft by addressing the potential risks associated with aging wiring systems. These regulations encompass various aspects, including wire selection, routing, separation, protection, bonding, and maintenance practices. Compliance with EWIS requirements helps prevent electrical failures, arcing, and wire degradation, which can pose serious safety hazards. By implementing proper maintenance and inspection procedures outlined in EWIS, aviation stakeholders can effectively manage and mitigate the risks associated with aircraft electrical wiring systems, ensuring the ongoing airworthiness and safety of the aircraft.

Course Overview

This course provides delegates with an overview of the development of enhanced aeroplane EWIS maintenance and the Enhanced Zonal Analysis Procedure.

Delegates will also learn about the technical aspects of typical EWIS installations, supporting inspection techniques and an introduction to AMC 20-22 Aeroplane EWIS training programmes.

This course is suitable for individuals involved in EWIS, either in a regulatory oversight capacity, or within industry managing training on EWIS.

This training course will include the following topics:

  • Safe handling of Aeroplane Electrical Systems
  • Line replaceable units (LRU)
  • Tooling
  • Troubleshooting procedures and electrical measurement
  • Construction and navigation of typical aeroplane wiring system overhaul or wiring practices manuals
  • Types of inspection
  • Human factors in inspections
  • Zonal areas and typical damage
  • Contamination sources, materials, cleaning and protection procedures
  • Correct identification of different wire types
  • Inspection criteria and damage tolerance
  • Repair and preventative maintenance procedures
  • Procedures to identify, inspect and find the correct repair for common types of connective devices found on typical aeroplanes
  • Procedures for replacement of all parts of common types of connective devices found on typical aeroplanes

At the end of this course, the participants will be able to:

  • Understand the basis of enhanced aeroplane EWIS maintenance
  • Understand the philosophies behind the Enhanced Zonal Analysis Procedure
  • Understand the broad technical aspects of enhanced EWIS inspection techniques
  • Demonstrate an overall knowledge of the elements needed in an effective EWIS training programme
  • Understand the regulatory expectations for effective delivery of initial and recurrent EWIS training in an approved organisation under their regulatory oversight

Delegates would benefit from having had exposure to, or experience of approved maintenance programmes, aircraft maintenance manuals, aircraft wiring diagrams, and other such instructions for continuing airworthiness.
