£40.00
EWIS TG 1&2 INITIAL COURSE
This EWIS course complies with EASA AMC 20-21 &AMC 20-22 and FAR 25, Subpart H—Electrical Wiring Interconnection Systems (EWIS)
ABOUT
This EWIS initial course is for;
TARGET GROUP 1 – Personnel Performing Electrical Wiring Interconnection Systems Maintenance. These personnel work directly at maintaining or modifying EWIS. Examples of these personnel are:
FAA – A & P technicians.
EASA – Part 66 Cat B1 and Cat B2 personnel.
TARGET GROUP 2 – Personnel Performing Maintenance Inspections on EWIS. These personnel perform EWIS inspections but do not directly maintain or modify EWIS. Examples of these personnel are:
FAA – A & P technicians.
EASA – Part 66 Cat B1 and Cat B2 personnel.
As engineers ourselves, we wanted to make the mandatory EWIS more interesting and relevant than older EWIS courses. If a course is interesting and informative then study becomes more enjoyable and less of an effort. Our EWIS course incorporate up to date incidents and accidents which have occurred this year which are relevant to aircraft engineers as opposed to the more traditional courses that focus on events from 30+ years ago. Our EWIS course also includes up to date relevant incident and accident information and practical knowledge on wiring and electrical manuals that will be of real use to engineers.
