What is the last action in the exit door disarming procedure?

The final step in the exit door disarming procedure involves pulling the strap. This action is crucial as it helps to deactivate the door's automatic opening mechanism, ensuring that the door does not inadvertently engage while passengers are boarding or deplaning. By pulling the strap, any tension on the door's operating system is relieved, allowing the door to be safely managed.

Each step in this procedure is essential for maintaining safety and operational integrity, with pulling the strap serving as the concluding action that fully confirms the door's disarmed state. This ensures that all crew members can confidently manage the exit without the risk of accidental deployment.

In this context, the other steps have distinct purposes that lead up to this final action, but pulling the strap is specifically designated as the last step to confirm the disarming process is complete.
