Who Should Take This Course?

EASA categorizes EWIS training into Target Groups (TG) based on job responsibilities:

  • TG1: Qualified staff performing EWIS maintenance, including avionics technicians, skilled workers, and B2 engineers. Training tailored to wiring systems maintenance tasks
  • TG2: Qualified staff performing EWIS inspections, including inspectors and B2 engineers performing inspections. Training is focused on wiring system inspection procedures.

Important Note on Module G (Connective Device Repair):
This online course does NOT cover Module G, which involves hands-on training for connector repairs. To complete Module G, learners must download the Practical Task Sheet upon login. Full certification is granted only upon submission of a signed and stamped task sheet from a Part-145 organization confirming competence.

For larger groups, an instructor-led Module G session can be arranged at client premises.
