We offer 3 EWIS courses. Each one combines the requirements for the Groups named, where there is very little difference in the requirements for those Groups:

  1. EWIS for Groups 1 & 2 - B2, full B1*, avionic technicians performing wiring work. B2 Inspectors.
  1. EWIS for Groups 4 & 5 - All other maintenance staff and inspectors working on aircraft and  This means all, including painters, seat technicians etc.
  1. EWIS for Groups 6, 7 & 8 - Handling staff, fuellers, loaders, cleaners, pilots, cabin staff.

Although AMC 20-22 includes B1 in the examples of Group 4 staff, it is generally agreed that full B1s are in Group 1.  B1s with electrical limitations are in Group 4.

Each course covers the EASA syllabus (AMC 20-22) for its Target Group comprehensively. The course for Groups 1 and 2 is in 2 Parts to cover the large volume of material needed.

Group 1 (only) students must complete a Practical Module G. We provide a task sheet which a student can get signed up in any Part 145 organisation, to satisfy Module G requirements for demonstrating competence on typical connectors.
