Aircraft Wiring

FAA-accepted 40 hours of instruction with a heavily focused hands-on course, fundamental for all A&P and Avionics technicians. This course was designed with this concept: repairing wiring can be much harder than installing it in a new aircraft - therefore, the technician needs to be better prepared to perform a job in this area.

The course examines different types of electrical wires and cables, various preparation and fabrication techniques (cutting, stripping, crimping, soldering, and tying) and installation issues (segregation, tie-wrapping, and chafing). The class also includes:

  • Nomenclature breakdown, deciphering, and labeling
  • Wiring and connector type identification
  • Aviation harness fabrication and installation requirements

14 CFR Part 121 regulations require significant Electrical Wiring Interconnect Systems (EWIS) training for all Technicians and Inspectors. The guidance used to identify and meet these training needs is contained in FAA Advisory Circular (AC) 120-94. This course addresses EWIS compliance concerns for Group 1 (Maintenance Personnel-Repairs), Group 2 (Inspection Personnel), and Group 4 (Maintainers-Removal & Installation of Equipment). We also discuss contemporary incidents, their causes, and the appropriate prevention.

Students will complete specific lab exercises as directed by the instructor, and each classroom is fully equipped and stocked with practice materials and standard tools used in the wiring installation and repair environment. Any relevant in-house tooling and supplies may be brought into the training session for evaluation and classroom use.
