MIL-HDBK-522B, DEPARTMENT OF DEFENSE HANDBOOK: GUIDELINES FOR INSPECTION OF AIRCRAFT ELECTRICAL WIRING INTERCONNECT SYSTEMS (20-NOV-2018)

MIL-HDBK-522A, DEPARTMENT OF DEFENSE HANDBOOK: GUIDELINES FOR INSPECTION OF AIRCRAFT ELECTRICAL WIRING INTERCONNECT SYSTEMS (20-NOV-2018)., This handbook provides guidance and lessons learned in the inspection of EWIS. This handbook is for guidance only and cannot be cited as a requirement. If it is, the contractor does not have to comply. This handbook is a guide for aircraft Electrical Wiring Interconnect System (EWIS) inspection. In case of conflict between the aircraft/platform-specific maintenance manual and this handbook, the platform specific manual will take precedence. Not all possible wire systems factors have been addressed. This handbook captures in one document, under suitable subject heading, fundamental installation criteria guidelines. The opportunity to focus on a single document results in substantial savings to the Government. All aircraft are filled with miles of wiring and hundreds of wiring devices that connect and transfer power and signals to and from electrical components. Virtually all aircraft systems rely heavily on some type of wiring for safe operation. Much like the structural components of an aircraft, the health and integrity of the EWIS can be significantly compromised due to premature aging, damage, and failure of wiring insulation. It is integral to the overall maintenance and sustainment of all aircraft that the EWIS be treated as a system and as a system be afforded the same level of importance as the aircraft structure and other critical flight control systems
