The AMC highlights that visual inspection of wiring has inherent limitations, as small defects like breached or cracked insulation, especially in small gauge wire, may not always be apparent. Therefore, effective wiring maintenance should combine visual inspection techniques with improved wiring maintenance practices and training to ensure comprehensive oversight.

Training personnel who are not directly involved in EWIS maintenance is important because they can inadvertently impact EWIS safety through actions such as cleaning or performing unrelated maintenance. By enhancing their awareness of EWIS safety, the AMC aims to prevent adverse impacts on EWIS integrity, ensuring that proper attention is paid to EWIS issues during their work.

The objectives of the AMC are to provide approved organisations with acceptable means of compliance with their training obligations as specified in various regulatory paragraphs related to EWIS. It encourages operators, holders of type certificates, maintenance organisations, and others involved in modifications or repairs to rethink their approach to maintaining and modifying aeroplane wiring and systems, ensuring that EWIS is maintained with the same intensity as other aeroplane systems.
