When having a missing tool investigation, who is notified first?

In a missing tool investigation, the first notification goes to maintenance control. This is because maintenance control is responsible for overseeing all maintenance operations and ensuring that safety protocols are followed. They need to be informed immediately to take appropriate actions, such as accounting for all tools on the aircraft and preventing any potential incidents caused by a missing tool.

Once maintenance control is notified, they can then coordinate with other parties, such as the maintenance officer, quality assurance officer, and the aircraft pilot, as needed to manage the situation effectively. This structured approach helps ensure a thorough investigation and minimizes risks associated with tool accountability in an operational environment.
