Electrical Wiring Interconnection Systems (EWIS) Target Groups 1 to 8

Compliant to EASA AMC 20-22 (Amdt 23)

For decades aircraft wiring was treated as a secondary installation. Major air transport accidents and ageing fleet data revealed a different truth: wiring is an open, complex system that needs its own safety analysis and its own maintenance philosophy.

Targeted for safety: Target Groups 1 to 8

This e-learning programme is built strictly in accordance with EASA AMC 20-22, so your team masters the skills needed to identify, maintain and protect the electrical pathways that keep modern aircraft in the air. AMC 20-22 sets specific target groups so personnel receive training suited to their operational impact. The course covers Target Groups 1 to 8. The two groups set out below carry the requirements for certifying, technical and inspection staff.
Certifying staff & technicians

Target Group 1

Personnel who perform EWIS maintenance, troubleshooting and alterations. Focused on clean, precise hands-on standards, wire routing and repair techniques.

Inspection staff

Target Group 2

Personnel who perform EWIS visual inspections, detailed inspections and quality audits. Refines the eye to catch subtle degradation, chafing and environmental hazards before they trigger system failures.

The EWIS core principle

A wire that looks perfectly fine on the outside can be failing on the inside through ageing polymer degradation or incorrect bend radius stress. This training moves your team from a reactive repair mindset to a proactive degradation-prevention mindset.

Syllabus

What the course covers

The curriculum maps directly to the training objectives in Appendix A and B of AMC 20-22.
01

Safety practices and environmental hazards

Recognising the dangers of improper wire handling and contamination: fluid ingress, metal shavings and chemical exposure.

02

Cleanliness and zonal inspections

Implementing the protect and clean as you go philosophy, and what constitutes a proper EWIS inspection within specific aircraft zones.

03

Wire routing and clamping standards

The technical rules for bend radii, clamping, clearance to structures and separation from high-heat or fluid lines.

04

Connectors and termination

Identifying damage within electrical connectors, backshells and shielding termination.

05

Human factors in wiring

How complacency, poor lighting or rushed work lead to latent wiring defects.

Delivery

Built for corporate and individual compliance

100% AMC 20-22 compliant

Formulated to meet the expectations of European and national aviation authorities during organisational audits.

High-quality visuals and scenarios

Macro photography of real aircraft wiring discrepancies, so inspectors know exactly what failure looks like in the hangar.

Advanced narration

Interactive voice-over guiding you through the in-depth material.

Instant verification

A secure, downloadable certificate is generated automatically on achieving a passing score in the final assessment.

Buying a single seat takes two minutes and access is immediate. For a team we open a corporate account with bulk pricing, a package built around your approval scope, and consolidated certificate records for your next audit.
