Who approves the work order that assigns a Job Control Number (JCN)?

The approval of the work order that assigns a Job Control Number (JCN) is typically the responsibility of Maintenance Control (MC). This is because Maintenance Control is primarily concerned with the planning, coordination, and scheduling of maintenance work on aircraft. When a maintenance task is identified, Maintenance Control assigns a JCN to ensure that the work is tracked properly within the maintenance management system. This allows for effective oversight of maintenance activities and ensures that resources are allocated appropriately.

While Quality Control, Logistics Support, and the Aircraft Custodian play important roles in the maintenance process, they do not directly approve the work order that includes the JCN. Quality Control focuses on maintaining standards and ensuring that maintenance work meets specified requirements. Logistics Support provides the necessary materials and support for maintenance activities. The Aircraft Custodian typically oversees the configuration and status of individual aircraft within the fleet but does not handle the administrative processes of work order approval. Therefore, Maintenance Control is the correct entity responsible for this specific approval process.
