Definition
An itemized document, prepared by an aircraft or component manufacturer, that lists every part used in an aircraft, engine, or accessory. Each part is identified by its part number, name, and quantity, and is referenced to the assembly or section of the equipment in which it is installed. The parts list is used by mechanics to order replacement parts and to verify that the correct part is being installed.
