This is tool control as per the 4790.2B. The primary objective of the tool control program is to eliminate accidents due to missing tools, and also to minimize the cost of replacing a tool. Due to the fact of human error there will be times when a tool does come up missing or broke it is inevitable. In case you ever do lose a tool or break it there are some steps that should be followed and if done properly will provide for the smoothest way to find a missing tool. Take care though because if a tool is broken and you cannot find all the pieces it will be considered a missing tool.
The first few steps are simple. First take a few moments to thoroughly search the area just in case that the tool was mistakenly placed in a pocket or someone near picked it up. Than you notify Maintenance Control (or if you are I-Level) Production Control will be notified of the missing or broken tool. Maintenance Control will than stop any job on that aircraft and recall any aircraft that are flying to come back if the tool was on the aircraft. Then the Desk Sergeant will be notified, once they have been notified you need to start a missing / broken / worn tool report. If you are the one that notices the tool missing or broken you will be the one filling out the report. Now that you have filled out the report, it needs to go over to Maintenance control.
