EWIS regulations were created by the U.S. Federal Aviation Administration (FAA) after a couple major airline incidents in the late 1990s. Failures attributed to electrical wiring aboard these aircraft were thought to be a major contributor to these accidents. In response, the FAA published updated EWIS regulations and guidance for original equipment manufacturers (OEMs) and suppliers. For any new platform today, adhering to EWIS regulations is a mandatory procedure for commercial aircraft certification.
