What is the first step in the 5-step process for missing tools?

Notifying Maintenance Control (MC) is the first step in the process for missing tools because it ensures that the appropriate personnel are made aware of the situation immediately. This notification allows Maintenance Control to assess the implications of the missing tool on aircraft operations, prioritize corrective actions, ensure safety procedures are followed, and activate any necessary measures to prevent further complications.

Initiating a lost tool report is an important part of the process, but it typically occurs after informing Maintenance Control, which can provide guidance and support. Conducting a search for the missing tool is also critical; however, it should be done under the direction of Maintenance Control in order to follow established protocols. Placing the aircraft in "down" status may be necessary for safety reasons but usually follows after notifying MC and determining the extent of the issue. Thus, notifying Maintenance Control is crucial for coordinating the appropriate response to the missing tool.
