If you see an X on the right column of a status sheet, what does that indicate?

• A. Deferred maintenance
• B. Flexible maintenance
• C. Routine maintenance
• D. Non-routine maintenance

Answer: (B)

An X in the right column of a status sheet signals flexible maintenance. This means the item isn’t required to be done immediately, but it can be scheduled within a defined window or rearranged to fit ongoing operations while still meeting the aircraft’s overall maintenance program. It gives the operator discretion to balance flight schedules with maintenance tasks, as long as the work is completed within the permitted timeframe. Deferred maintenance would imply a formal postponement beyond the allowed window; routine maintenance refers to regularly scheduled tasks; non-routine maintenance covers unscheduled corrective actions.
