Maintenance Tracker
Centralised maintenance oversight, compliance tracking, and job card management for your aircraft fleet.
1 What's on this page
The Maintenance Tracker is the primary tool for managing all aspects of aircraft maintenance. It provides comprehensive visibility into maintenance status, compliance requirements, and work planning across your entire fleet.
Two Main Tabs
- Maintenance & Logbooks: Track maintenance items, defects, directives, and tasks for each aircraft with detailed interval management
- Job Cards: View, manage, and track all maintenance job cards across the fleet in a centralised register
Key Capabilities
- Monitor maintenance status for active and deactivated aircraft
- Track scheduled maintenance actions, technical directives, defects, and ad hoc tasks
- Manage maintenance intervals, due dates, and remaining time calculations
- Create and complete maintenance jobs with digital job cards
- Request and review extensions for MEL defects and ad hoc tasks
- Generate detailed maintenance reports and forecasts
The Maintenance Tracker integrates with the broader Maintenance Hub system, including the maintenance library (scheduled action types), logbooks, inventory, and aircraft configuration. Changes made in the tracker automatically update related systems.
Access requires maintenance hub permissions. Different roles see different capabilities—administrators can edit all content, while maintenance staff may have view-only or limited edit access depending on configured permissions.
2 Maintenance & Logbooks tab
The Maintenance & Logbooks tab is the primary interface for tracking maintenance across your aircraft fleet. It shows all aircraft in a searchable table with quick access to detailed maintenance tracking for each aircraft.
2.1 Aircraft list view
The aircraft table displays all aircraft with their maintenance status and library assignment status. Use this view to get a high-level overview of fleet maintenance and navigate to detailed aircraft views.
Top Controls
- Search (top-left): Filter aircraft by registration, serial number, aircraft model, type designator, or operator name
- Active/Deactivated toggle (centre): Switch between viewing active aircraft and deactivated aircraft
- Action buttons (top-right):
- Aircraft Utilisation Report: Generate PDF showing flight hours and cycles for selected period
- Forecast Report: Generate PDF forecasting upcoming maintenance requirements

2.2.4.3 Directive categories
One-time
Directives requiring single compliance. Once completed, no further action needed unless component replaced.
Recurring
Directives requiring periodic compliance at defined intervals (e.g., every 100 hours or 12 months).
Terminated
Directives with terminating actions. Once specific action performed, no further compliance required.
2.2.4.4 Viewing terminated directives
By default, the table shows only active directives. Terminated directives (those with completed terminating actions) are hidden to reduce clutter.
To view terminated directives:
- Expand the airframe/engine/propeller row
- If terminated directives exist, a special row appears with italicised text: "Terminated directives (X)"
- Click this row to expand and view all terminated directives
2.2.5 Scheduled Maintenance Actions table
The Scheduled Maintenance Actions table displays all routine maintenance tasks from the aircraft's maintenance library. These are ongoing maintenance requirements like inspections, checks, services, and replacements scheduled at regular intervals.
2.2.5.1 Table structure
Like Technical Directives, this table uses a hierarchical structure with more depth:
- Level 1: Airframe, engines, propellers (expandable)
- Level 2: Maintenance folders (groups of related actions, e.g., "Daily Checks", "100-Hour Inspection")
- Level 3: Individual maintenance action types within each folder
- Level 4: Parts fitted to components

| Remaining Interval columns | Flight hours, landings, engine hours, engine cycles, N1/N2, propeller hours, estimated days, and due date |
2.2.5.3 Understanding intervals and due dates
Maintenance intervals can be based on multiple metrics. The system tracks all applicable metrics and uses the most restrictive (nearest due) to determine when work is required.
Interval Types
- Flight hours: Total airframe hours
- Landings: Total aircraft landings/cycles
- Engine hours: Running time per engine
- Engine cycles: Start/stop cycles per engine
- N1/N2: Turbine cycle counts (turbine engines only)
- Propeller hours: Running time per propeller
- Calendar time: Months or days since last compliance
Due Date Calculation
The system calculates estimated due dates based on:
- Current remaining interval values
- Historical utilisation rates (average hours per day, landings per day, etc.)
- Most restrictive metric determines the final due date
2.2.6 Ad Hoc Tasks table
Ad Hoc Maintenance Tasks are unscheduled maintenance items created for specific situations not covered by scheduled actions or technical directives. These might include customer requests, damage repairs, modifications, or one-off inspections.
2.2.6.1 Managing ad hoc tasks

6 Troubleshooting and FAQs
Common questions and solutions for Maintenance Tracker issues.
6.1 Why can't I see some aircraft in the list?
Possible reasons:
- You're viewing Active aircraft, but the aircraft is deactivated (or vice versa). Use the Active/Deactivated toggle to switch views.
- Filters are applied that exclude the aircraft. Check the filter panel and clear filters if needed.
- You don't have permission to view that aircraft (rare—usually applies to multi-operator setups with restricted access).
6.3 Why can't I select a maintenance item for a job card?
Possible reasons:
- The item is already part of an in-progress job card. Complete or edit that job first.
- The item has been terminated (for technical directives and scheduled actions with terminating conditions).
- The item is not yet due or has been completed recently.
6.5 Why are my interval calculations showing unexpected values?
Possible reasons:
- Logbook entries are missing or incorrect. Check logbooks for the aircraft/component to ensure hours and cycles are accurately recorded.
- The maintenance action was completed early or late, affecting the next due calculation.
- Intervals were manually adjusted during job card completion.
- Component was recently installed or replaced—intervals reset to zero or adjusted values.
Resolution: Review logbook entries and maintenance history. If values are incorrect, contact your maintenance manager to make corrections.
6.6 Why can't I delete a job card?
Reason: Job cards can only be deleted if no work has been performed and no actions are completed. This protects audit integrity.
Resolution: If the job card was created in error and work has started, you cannot delete it. Instead, complete the job card normally or leave it marked as in-progress. If significant errors occurred, consult your quality manager about corrective actions.
6.7 What if I complete a job card with the wrong date?
Impact: Incorrect completion dates affect all interval calculations and can throw off the entire maintenance schedule.
Prevention: Always double-check the completion date and time before saving. The system defaults to the current date/time, but you can edit it if work was actually completed earlier or later.
Resolution: Once saved, job cards cannot be easily re-opened. Contact your system administrator or quality manager immediately if you discover an error. They may need to make database adjustments or create compensating logbook entries.
6.8 How do I know which maintenance items are next due?
Answer: When you click Add Maintenance Job, the system automatically pre-selects items calculated to be next due based on current intervals and utilisation forecasts. You can review the selections and adjust as needed.
Additionally, look for:
- Red or yellow interval badges (approaching or overdue)
- The Min. Days column (if enabled) showing small numbers
- Items with the earliest due dates in the Due date column
6.9 What happens if I don't complete maintenance before the due date?
Answer: Depending on the type of maintenance:
- Mandatory items (ADs, critical checks): Aircraft becomes grounded/AOG automatically. Cannot fly until maintenance is completed.
- Scheduled maintenance within tolerance: Caution status appears, but aircraft may still be serviceable. Plan maintenance urgently.
- Non-critical items: May continue operating if within acceptable limits, but should be addressed promptly.
Always consult your maintenance program and operations manual for specific requirements. When in doubt, ground the aircraft until maintenance is current.
