# How to Manage Due Items
> Track maintenance items, inspections, ADs, and service bulletins by aircraft with time-based, cycle-based, and calendar-based tracking.
By following this guide, you will create and manage maintenance due items across your fleet,
track time-based and cycle-based intervals, configure warning thresholds, complete items to
reset recurrence, and monitor your fleet's upcoming maintenance obligations.
**Who should read this:** Directors of maintenance, maintenance controllers, and maintenance
planners responsible for tracking inspection intervals, AD compliance, and scheduled
maintenance tasks.
**Required permission:** `maintenance_ops` -- read to view, update to create and modify due
items. Complete permission is required to record task completions.
**Regulatory basis:** 14 CFR 91.409 requires inspections at specified intervals. 14 CFR 91.417
requires operators to maintain records of current status of applicable ADs and inspections.
14 CFR 135 Subpart J establishes continuing airworthiness maintenance program (CAMP)
requirements for Part 135 operators.
## The Due Items List
Navigate to **Maintenance > Due Items** to see all tracked maintenance items across your fleet.
The page groups items into three categories via tabs:
| Tab | What it tracks |
| -------- | ---------------------------------------------------------------- |
| Pilot | Pilot certificates, medicals, currency, and training due dates |
| Aircraft | Aircraft inspections, ADs, overhauls, and component replacements |
| Company | Insurance, registrations, and company-level compliance items |
Each tab displays items with color-coded status badges:
| Status | Color | Meaning |
| -------- | ----- | -------------------------------------------- |
| Current | Green | Not yet within warning threshold |
| Due Soon | Amber | Within warning threshold but not yet overdue |
| Overdue | Red | Past the due date, hours, or cycles |
## Create a Due Item
### Open the new due item form
From the Due Items page, click **New Due Item**. The form opens with all tracking fields.
### Select the aircraft
Choose the aircraft registration. Due items are always scoped to a specific aircraft tail number.
### Enter item details
Fill in:
* **Name** -- Descriptive label (e.g., "100-Hour Inspection", "AD 2024-12-06 Compliance")
* **Description** -- Detailed description of the maintenance requirement
* **Task Type** -- Inspection, Service, Overhaul, Replacement, AD, SB, or CMR
* **ATA Chapter** -- The applicable ATA 100 chapter code (e.g., "32" for Landing Gear)
* **Reference** -- AMM, EMM, AD, or SB document reference number
* **Category** -- Inspection, AD, SB, Component, Engine, Airframe, Avionics, or Other
* **Priority** -- Low, Normal, High, or Critical
### Configure due tracking
Select the **Due Type** that governs when this item comes due:
| Due Type | Tracks by |
| ------------------ | --------------------------------------- |
| Hours | Flight hours (e.g., due at 3,500 hours) |
| Cycles | Engine or landing gear cycles |
| Calendar | Calendar date (e.g., every 12 months) |
| Hours and Calendar | Whichever limit is reached first |
| Landings | Number of landings |
Enter the applicable due values:
* **Due Hours** / **Due Cycles** / **Due Landings** -- The limit at which action is required
* **Due Date** -- Calendar due date for time-based items
### Set warning thresholds
Warning thresholds determine when an item transitions from "current" to "due soon":
* **Warning Hours** -- Hours before due to trigger the warning (e.g., 50 hours)
* **Warning Cycles** -- Cycles before due
* **Warning Landings** -- Landings before due
* **Warning Days** -- Calendar days before due date
Set warning thresholds that give your maintenance team enough lead time to plan and schedule the
work. For heavy inspections, 60--90 days is common. For simple tasks, 30 days may suffice.
### Set tolerances (optional)
Tolerances define the allowable overrun beyond the due point before the aircraft must be
grounded:
* **Tolerance Hours** / **Tolerance Cycles** / **Tolerance Landings** / **Tolerance Days**
Tolerances are operational allowances, not regulatory extensions. Exceeding tolerance limits may
render the aircraft unairworthy. Always confirm tolerance applicability with the manufacturer's
maintenance program and applicable FAA approvals.
### Configure recurrence
For recurring items, toggle **Is Recurring** on and enter the repeat interval:
* **Interval Hours** -- Repeat every N flight hours
* **Interval Cycles** -- Repeat every N cycles
* **Interval Landings** -- Repeat every N landings
* **Interval Months** -- Repeat every N calendar months
When a recurring item is completed, PlaneConnection automatically calculates the next due
values based on the interval and the completion point.
### Set component tracking (optional)
For items tied to a specific component (life-limited parts per 14 CFR 43.10):
* **Component Name** -- Name of the tracked component
* **Part Number** -- Manufacturer part number
* **Serial Number** -- Component serial number
* **Position** -- Installed position (Engine 1, Engine 2, LH, RH)
* **Engine Number** -- For multi-engine aircraft, which engine (1, 2, or 3)
### Create the due item
Click **Create** to save. The system calculates the initial status based on current aircraft
times and opens the item in the list.
## Complete a Due Item
### Open the completion form
From the due items list, click the actions menu on the target item and select **Complete**.
### Record completion data
Enter:
* **Completed At** -- Date of completion
* **Completed Hours** -- Aircraft hours at completion
* **Completed Cycles** -- Aircraft cycles at completion
* **Completed Landings** -- Landings at completion (if applicable)
* **Completed By** -- Name of the person who performed or supervised the work
* **Work Order** -- Link to the associated work order (if applicable)
### Submit completion
Click **Complete**. For recurring items, the system automatically resets the item and
calculates the next due values based on the configured interval. The status returns to
**Upcoming** and the next due fields are populated.
## Snooze a Due Item
For items that need a temporary extension, use the **Snooze** action from the item's actions
menu. Enter the new due date and a reason for the adjustment. Snooze events are audit-logged
with the adjuster's identity, timestamp, and stated reason.
## Filter and Search
Use the toolbar to narrow results:
* **Search** -- Matches against item name, description, or reference
* **Aircraft** -- Filter to a single aircraft
* **Category** -- Filter by maintenance category
* **Status** -- Filter by current, due soon, or overdue
## Calendar Integration
Items with **Add to Calendar** enabled appear on the Maintenance Forecast calendar view,
providing a visual timeline of upcoming maintenance obligations across the fleet.
