As a minimum, units shall print a new MDL how often for each aircraft assigned to the unit?

• A. Daily
• B. Weekly
• C. Once a month
• D. Quarterly

Answer: (C)

The main idea is keeping maintenance data current and actionable. The MDL is the authoritative record used to plan and execute maintenance for each aircraft, so it has to reflect the latest status, modifications, and due items. Printing a new MDL at least once a month ensures changes—such as new maintenance due dates, component status, or recent modifications—are captured and distributed in time for proper planning. If updates were only quarterly, or even less frequent, crews could be acting on outdated information, risking overdue tasks or mismatches between what’s planned and what’s actually on the aircraft. Daily or weekly updates would be unnecessarily burdensome, while monthly provides a practical, sustainable cadence that keeps the data fresh without overloading the process.
