By the end of this guide, you will have monitored maintenance due items, reviewed status across your fleet and crew, updated item status after maintenance, and used due item tracking to prevent grounding events.
The Operations module must be enabled for your workspace. You also need the appropriate operations permissions. Contact your workspace administrator if you cannot access these features.
You need the maintenance_ops.read permission.

​
Prerequisites

  • Aircraft must be registered in the fleet with accurate total time and total cycles.
  • Crew members should have certifications entered with expiry dates.
  • Due items should be configured in Settings > Maintenance > Due Items with appropriate tracking parameters.
Open the Operations sidebar and click Due Items under the Fleet group. The sidebar badge on Due Items displays the count of overdue items in red when any exist. The page loads with a summary bar and a tabbed table of all tracked items. Breadcrumb path: Ops > Due Items

​
Understand the summary bar

The top of the page shows four color-coded status badges that summarize the health of your entire operation:
BadgeColorMeaning
Current (>60 days)GreenItems that are not within any alert window.
Due Soon (30—60 days)YellowItems approaching their due threshold.
Due Soon (<30 days)Light redItems due within the next 30 days — higher urgency.
OverdueRedItems where the due parameter has been exceeded.
Click any badge to filter the table to that status group. These counts give you an at-a-glance health check across your entire operation.

​
Filter by category

The Due Items table has four tabs:
TabContents
AllEvery tracked item across all categories.
PilotCrew certifications, medicals, training due dates.
AircraftInspections, ADs, overhauls, service bulletins.
CompanyInsurance, registration renewals, company-level compliance.
Click a tab to filter the table to that category.

​
Review due items

Each row in the table shows:
ColumnDescription
ItemName or description of the due item.
EntityThe aircraft tail number or crew member name.
Due DateCalendar date when the item is due.
Days/Hours RemainingPositive number = days or hours until due; negative = days overdue.
StatusColor-coded label: current (green), due soon 30—60 days (yellow), due soon under 30 days (light red), or overdue (red).
Items are sorted by urgency — overdue items appear first, followed by items due soonest. The Fleet Health dashboard also includes a Due Items Matrix heatmap that displays aircraft (rows) against maintenance categories (columns) such as Annual, 100-hr, Phase, AD, SB, and Overhaul. Cell colors shift from green (more than 60 days) through yellow (30—60 days) to red (under 30 days) and dark red (overdue). Click any cell in the heatmap to navigate directly to that due item.
Click any row to open the item detail page where you can view the full tracking history, add notes, and update the status.

​
Update a due item status

When maintenance or training is completed:
  1. Open the due item detail page.
  2. Enter the completion date and any relevant data (hours at completion, next due value).
  3. Change the status to reflect the new state.
  4. Click Save.
The system recalculates the next due date based on the interval and the completion data.

​
Use TaxxAll Aviator for advanced tracking

For operators using the TaxxAll Aviator integration, navigate to Dispatch > Aircraft > TaxxAll Aviator for an enhanced view that organizes due items into three tabs:
  • Due by Date — calendar-based items.
  • Due by Hours — time-based items.
  • Due by Landings — cycle-based items.
Each item card shows the aircraft registration, item description, due value, current value, remaining margin, and urgency status.
Do not let items go overdue without documented justification. Overdue items may ground the aircraft and can result in FAA compliance findings during inspections.
