How should cabin crews report unserviceable service equipment?

The appropriate procedure for reporting unserviceable service equipment is to call for its removal and tag it with an unserviceable seal. This method ensures that the equipment is officially designated as unserviceable, preventing its use and maintaining safety standards on the aircraft. By tagging the equipment, other crew members are made aware of the issue, and it can be addressed properly during maintenance checks. This creates a clear line of communication within the cabin crew and ensures that appropriate actions are taken to resolve the issue.

Notifying passengers does not address the operational safety concerns and may lead to confusion regarding the unserviceable item. Reporting only through the captain could delay necessary actions and does not provide an immediate solution. Logging the issue in the safety book, while important for records, does not offer a real-time solution for crew members or address immediate safety concerns during the flight. Thus, calling for removal and tagging with an unserviceable seal is the most effective and responsible approach.
