Controlled exchange involves the removal of serviceable components from which type of item?

Controlled exchange refers to a process where serviceable components are removed from items that are deemed unserviceable but are cost-effective to repair. This is particularly relevant for economical repairable end items, as these items have a value that justifies repair efforts when components can be salvaged and reused.

In the context of aircraft maintenance, controlled exchange allows for the efficient management of resources by enabling maintenance teams to salvage parts from unserviceable units to ensure operational readiness of other aircraft. This practice is vital for maintaining a fleet's efficiency and minimizing downtime, as it allows serviceable components to be reallocated to aircraft that require them without having to wait for repairs on the larger, unserviceable units.

This process promotes resourcefulness in maintenance and allows for better utilization of available assets, aligning with the principles of cost-effectiveness within military logistics and operations.
