New Part 121 regulations require significant electrical wiring interconnect systems (EWIS) training for technicians and inspectors. Global Jet Services has developed the Practical Aircraft Wiring course for Group 1 (Maintenance Personnel-Repairs), Group 2 (Inspection Personnel) and Group 4 (Maintainers-removal & installation of equipment).
“Technicians have told us they haven’t had adequate training,” J.D. McHenry, president of Global Jet Services, told AIN. “The reality is maintenance technicians don’t get a lot of experience, yet everyone recognizes faulty wiring can be a substantial risk.”
McHenry said the five-day course covers cutting, stripping, crimping, soldering, splicing and fabrication for different types of electrical wire and cable, as well as installation issues such as segregation, tying, tie wrapping and chafing problems. Discussions will also include recent electrical incidents and their causes and prevention, with particular attention to inspection of existing wiring. The course is hands on and all tools necessary to take the class are provided.
The seminars are presented an average of once a month and they tend to fill early. Currently still open are: Teterboro, N.J. (April 16 to 20); and Lee’s Summit, Mo. (June 25 to 29). McHenry anticipates adding classes during the year.
