Maintenance
Maintenance tracks what each airframe is due for and when it was last done. Find it under Maintenance in the nav for the whole fleet at once, or on a single aircraft’s Maintenance tab.
Maintenance is part of the always-on compliance floor — it isn’t behind a module switch.
Maintenance items
Section titled “Maintenance items”An aircraft carries maintenance items: propeller replacement, motor inspection, battery cycle check, whatever the airframe actually needs. Each item has an interval:
- Flight hours — “Every 50 flight hrs”, counted from the aircraft’s logged hours.
- Calendar days — “Every 180 days”, counted from the last service date.
An item can carry a second interval too — hours or days, whichever comes first. The status reflects the worse of the two.
Status
Section titled “Status”| Status | Meaning |
|---|---|
| OK | Under 90% of the interval. |
| Due Soon | 90% or more of the interval used. |
| Overdue | The interval has been reached or passed. |
Status recalculates when you record a service — and also whenever a flight log changes the aircraft’s hours, so an hours-based item goes due on its own, without anyone remembering to check.
An item going overdue raises an alert.
Applying a template
Section titled “Applying a template”Rather than typing every item by hand, open an aircraft and use Apply maintenance template. Templates come from a catalogue: some are specific to an aircraft model, others are universal. Applying one creates its items on that airframe in one action.
Each template carries a confidence label, and the label is the point:
| Label | What it means |
|---|---|
| Manufacturer-confirmed | Published by the manufacturer, with a source citation. |
| Community estimate | Not manufacturer official. |
| Sample | Not manufacturer official — verify before relying on it. |
| Pending review | Not yet reviewed — verify before relying on it. |
Nothing that isn’t manufacturer-published is ever presented as though it were. Treat a community or inferred interval as a starting point to adjust against your own manufacturer documentation.
Applying a template again is safe: it refreshes thresholds without wiping the name, baseline or status you’ve adjusted on an item.
Custom items
Section titled “Custom items”+ Add custom item creates an item that no template covers — a name, a primary interval, and optionally a second one. Requires at least a Member role.
Recording service
Section titled “Recording service”Log Service on an item records what was done and resets its clock:
- Date performed
- Flight hours at service — required for a flight-hours item, since that’s what the reset is measured from
- Performed by
- Notes
- Attach receipt / sign-off — a PDF or image, filed into your document library against that service entry
Saving it resets the item’s last-service point and recomputes its status in one step.
Log Service is restricted to the workspace’s Account owner (the account holder). Every other maintenance write — adding a custom item, applying a template — only needs Member. This is a tighter floor than the rest of the module.
Each item keeps its service history, newest first, with the hours at service and whatever notes were recorded. An aircraft-scope compliance report prints each item’s last-serviced date and status.
A service record can show Awaiting return-to-service approval; the Account owner approves it from the record. The Maintenance page filters by Overdue / Due Soon / OK, and Admins and above can use Export history.
Some catalogue templates include a cycles interval (for example “every 200 cycles or 365 days”). Cycles are not counted yet, so only the calendar or hours part of such an item can make it due. New custom items cannot use cycles.
Airworthiness
Section titled “Airworthiness”The fleet view rolls maintenance status into a single status-at-a-glance badge per airframe: Grounded, Maintenance overdue, Maintenance due soon, Not tracked (no maintenance items), or Airworthy. A manual grounding always wins over maintenance state — if you’ve grounded an airframe, that’s what you see, regardless of what its items say. See Fleet.
“Airworthy” here means the aircraft has at least one maintenance item, none is overdue or due soon, and nobody has grounded it. Tobren Operations tracks your maintenance record; it does not certify airworthiness, and a compliance report doesn’t either. That determination stays yours.
