Final answer:
Personnel removed from aircraft maintenance responsibilities for 30 days or longer will receive an egress system checkout before performing any aircraft maintenance.
Step-by-step explanation:
When personnel are removed from aircraft maintenance responsibilities for 30 days or longer, they will receive an egress system checkout before performing any aircraft maintenance.
This safety measure is in place to ensure that personnel who have been away from their maintenance duties for an extended period are familiar with the egress system, which includes emergency exits and evacuation procedures. The egress system checkout helps to prevent any potential mishaps and accidents during aircraft maintenance.
