What is the main action required if ground support equipment is found to be malfunctioning?

The main action required if ground support equipment is found to be malfunctioning is to tag it out for servicing. This practice is crucial because it ensures that the equipment is clearly marked as out of service, preventing its use until it has been properly repaired. Tagging out malfunctioning equipment promotes safety for all personnel on the ground and helps avoid potential accidents or further damage to the equipment itself.

This procedure also facilitates a systematic approach to repairs, allowing maintenance personnel to be aware of which equipment needs attention and enables them to prioritize their work effectively. By following proper protocols for tagging out, the organization maintains operational integrity and adherence to safety regulations, ensuring a secure working environment.
