What system is designed to ensure each tool going on board an aircraft is accounted for?

The Tool Control system is specifically designed to ensure that each tool used for aircraft maintenance and operations is accounted for before and after maintenance tasks. This system includes processes for logging tools in and out, tracking their usage, and verifying that no tools are left behind in the aircraft after maintenance is completed.

Tool Control helps maintain safety in aviation by minimizing the risk of foreign object damage (FOD), which can occur if tools are inadvertently left in or around critical aircraft components. By effectively managing the tools and ensuring proper tracking and accountability, the Tool Control system plays a crucial role in maintenance practices and helps uphold the integrity and safety standards required in the aviation sector.

Other systems may have related functions but do not focus as specifically on the accountability and tracking process that Tool Control provides. For example, while a Tool Inventory might keep a list of available tools, it does not inherently include procedures for ensuring tools are matched with specific maintenance tasks or checked back in properly.
