What item is also useful in searching for lost hardware?

The item that is useful in searching for lost hardware is a mirror. A mirror allows personnel to see into hard-to-reach areas, helping to identify and locate small items that may have fallen or become misplaced in spaces that are not easily visible. Using a mirror can enhance the search process by providing the ability to look around obstacles, ensuring that no foreign objects are overlooked during inspections. This is particularly important in aviation and maintenance environments where even small pieces of hardware can pose serious safety risks if left unattended.

In contrast, while a camera can provide a visual record, it does not assist in the physical location of items in tight or obscured spaces. A drill and a wrench are tools associated with assembly and repair rather than searching for lost items. They serve specific functional purposes but do not aid in scanning or inspecting areas for misplaced hardware.
