When should the flight attendant notify the PIC regarding lavatory tampering?

Flight attendants should always notify the Pilot in Command (PIC) regarding lavatory tampering because it poses a potential safety and security risk onboard the aircraft. Proper communication about any signs of tampering—such as broken locks, suspicious items, or anything that seems unusual—is critical to ensure the safety of all passengers and crew.

Immediate reporting allows the PIC to assess the situation appropriately, which may involve monitoring the lavatory closely, alerting ground security upon landing, or taking further steps to ensure that passengers remain safe. This protocol is vital not just in response to complaints or specific incidents but as a standard practice to maintain the overall security of the flight at all times. Addressing these issues proactively rather than reactively can prevent larger problems from arising.
