This course will discuss the FAA Code of Federal Regulations (CFRs) and design concepts required to ensure all aspects of aircraft electrical wiring and installation are safe. It will examine aircraft wiring as a system and review all Part 25 CFRs related to EWIS FAA Certification. A review of FAA Advisory Circulars and practical applications of the information will be conducted as teams will be selected to simulate the EWIS certification process. EWIS requirements for aircraft maintenance and inspection will also be discussed.

Includes instruction, course materials, refreshments and lunches. The course notes are for participants only and are not for sale.
