What does direct Maintenance Cost (DMC) primarily consist of?

Direct Maintenance Cost (DMC) primarily consists of costs related to regular maintenance activities. This includes expenditures necessary to keep an aircraft safe, operational, and compliant with regulatory standards. Regular maintenance provides the essential framework for ensuring the reliability and performance of an aircraft, involving tasks such as inspections, repairs, replacements of worn parts, and routine servicing.

Understanding DMC is crucial for aviation finance and management as it directly impacts the operational budget and overall efficiency of an airline or maintenance service provider. The nature of these costs typically encompasses labor, parts, and materials directly associated with maintenance, thus forming a core aspect of an organization's expenditure in maintaining its fleet.
