This SAE Aerospace Information Report (AIR) shall be limited to information about a specific corrosion mechanism of silver-plated conductors that produces cuprous/cupric oxide deposits (Red Plague). It examines some possible causes and some recommendations to minimize the possibility of its occurrence. It also provides a number of reference documents that describe the corrosion in detail, methods to determine conductor damage, methods to produce the corrosion, and other investigative reports of this phenomena and their conclusions.
