About

The EWIS initial course is designed for:

Target Group 1 – Personnel Performing Electrical Wiring Interconnection Systems Maintenance. These individuals are directly involved in maintaining or modifying EWIS. Examples include:

  • FAA – A & P technicians.
  • EASA – Part 66 Cat B1 and Cat B2 personnel.

Target Group 2 – Personnel Performing Maintenance Inspections on EWIS. These individuals conduct inspections but do not directly maintain or modify EWIS. Examples include:

  • FAA – A & P technicians.
  • EASA – Part 66 Cat B1 and Cat B2 personnel.

As engineers, we aimed to make the mandatory EWIS training more engaging and relevant compared to traditional courses. By incorporating current incidents and accidents related to aircraft engineering, we strive to create a more enjoyable and informative learning experience. Our EWIS course includes up-to-date information on wiring, electrical manuals, and practical knowledge that engineers can apply directly in their work.
