Final answer:
The cognizant authority, such as the engineering or maintenance department, needs to be coordinated with for engine removals and teardown inspections requested by PMA. Coordination with the cognizant authority ensures an organized and safe process.
Step-by-step explanation:
When PMA (Programmed Maintenance Actions) request engine removals and accessory and component teardown inspections, the coordination must be done with the cognizant authority. The cognizant authority could be the engineering department or the maintenance department of the organization. They have the knowledge and expertise to ensure that the removals and inspections are carried out effectively and safely.
For example, if an aircraft engine needs to be removed for maintenance, the engineering department will coordinate with the maintenance department to plan the removal procedure, assign skilled technicians, and ensure compliance with safety regulations.
It is important to have coordination with the cognizant authority to ensure an organized and well-executed process, minimizing the risk of errors and ensuring the smooth operation of the maintenance activities.
