Electrical Wiring Interconnection System is the term for wiring as a collective incorporating all fittings and associated hardware as a system that transmits electrical signals between components or points on the aircraft.
The significance of the wiring to be considered as a system is an important aspect of awareness and has a history of being previously involved with aircraft incidents. Now with this increased knowledge and understanding we can address the risks and reduce the likelihood of wiring events occurring and causing such incidents.
Your role will define the target group you need to achieve:
Group 1 & 2 is for B1 & B2 licensed personnel and avionic skilled workers (note that Group 1 & 2 participants must complete the mandatory practical module (subpart G) and this is accomplished by completing the provided workbook which will for an appendix for your certificate.
- Target Group 1: Qualified staff performing EWIS maintenance.
- Target Group 2: Qualified staff performing maintenance inspections on EWIS.
Group 3 is for Electrical/avionic engineers.
- Target Group 3: Qualified staff performing electrical/avionic engineering on in-service aeroplane.
Group 4 & 5 is for Cat A licensed personnel or personnel performing other engineering and planning work.
- Target Group 4: Qualified staff performing general maintenance/inspections not involving wire maintenance (LRU change is not considered wire maintenance)
- Target Group 5: Qualified staff performing other engineering or planning work on in-service aeroplane.
Group 6 is for other service with duties in proximity to EWIS, for example refuellers, and de-icers.
- Target Group 6: Other service staff with duties in proximity to electrical wiring interconnection systems
Group 7 & 8 is for Flight Deck and Cabin crew.
- Target Group 7: Flight Deck Crew
- Target Group 8: Cabin Crew
A look at EWIS starting with the origins of what EWIS is and how the legislation requiring increased knowledge in this area came to be; we then look closely at what you need to know regarding the different aspects of awareness:
- General electrical wiring interconnection system practices (Levels 1,2,4,6,7 & 8)
- Wiring practices documentation (Levels 1,2 & 3)
- Inspection (Levels 1,2,4,5,6,7 & 8)
- Housekeeping (Levels 1,2,3,4,5,6,7 & 8)
- Wire (Levels 1,2,3,4,5,6,7 & 8)
- Connecting devices (Levels 1,2 & 3)
- Connective devices repair (Level 1 only)
The content of each is custom to the target group and covers different content for each accordingly.
Specifications course taught to:
Course is taught to achieve regulations as specified in EASA AMC 20-22 & FAA AC 120-94
Level 1 & 2 EWIS require that Subpart G (practical elements) be completed and as such a practical workbook is supplied and must be competed in order for your certificate to be valid.
All other Level’s 3 through to 8 do not have this requirement and are completed entirely online to satisfy the regulation requirements.
Suggested duration for completion is 6 hours for Level 1 & 2, 4 Hours for level 3 & 4, 3 Hours for remaining levels.
Interval for continuation
There is a requirement to have interval continuation training for this course every 24 months.
