Missing MX Records

What does Missing MX Records mean?

MX means maintenance. An aircraft can appear in your fleet while its maintenance tracking record is missing. This can prevent its maintenance counters from displaying correctly. The registration tool creates missing records using the configured maintenance defaults for each aircraft class.

Use this guide when an aircraft reports missing MX records or its maintenance information is absent. A counter reaching zero, an overdue check or an aircraft already in maintenance needs the normal maintenance workflow instead.

1. Open your airline's Fleet page

Sign in and go to Airline → Airline Operations → Fleet, or open Fleet directly. Check the airline name at the top so you know which fleet you are working with.

Note the registration of an aircraft showing the problem. You will use it to verify the result afterwards. You do not need to open each aircraft individually to run the registration tool.

2. Open Tools at the top

Find the row of buttons beneath the airline name and aircraft count. Click Tools, the button with the toolbox icon and dropdown arrow. It sits alongside controls such as Facilities and Fleet Restrictions.

In the dropdown, select Register Missing MX Aircraft, marked with a wrench icon. Choose that entry rather than Aircraft Image, which is a separate fleet tool.

3. Allow the registration to finish

Selecting the entry starts the repair for the airline selected by the Fleet page. The tool checks the airline's aircraft, skips aircraft that already have an MX record, and creates records where they are missing and the required aircraft-class defaults are available.

Existing MX records and their counters are left in place. This action does not perform an A, C or D maintenance check, complete workshop downtime or repair every possible maintenance configuration problem.

When the web action finishes, it redirects you back to the page you came from, normally Fleet. There may be no separate success dialog or report showing how many records were created. Returning to Fleet is your cue to check the aircraft, not proof that every missing record was repaired.

4. Verify the aircraft's maintenance information

1. Find the affected registration in the Aircraft List. Use the search field if needed.
2. Open that aircraft and refresh its details if you still have an older page open.
3. Check whether the missing-record warning has cleared and the maintenance counters now appear.
4. Review the A-Check, C-Check and D-Check information shown for that aircraft.
5. If several aircraft were affected, check those registrations too.

Once the information is present, use the displayed counters and aircraft status to plan any maintenance actually required. Registering a record does not itself mean the aircraft is ready to fly.

If records are still missing

First confirm that you ran the tool from the correct airline's Fleet page and refreshed the affected aircraft. If the problem remains, the aircraft type, class or maintenance defaults may need attention that this registration tool cannot provide. An existing but incomplete MX record is also skipped rather than rebuilt.

Do not keep running the tool to reset counters or clear an overdue check. Report the aircraft registration and ID, airline, exact warning and a screenshot of the maintenance area. Mention that you already tried Fleet → Tools → Register Missing MX Aircraft, and whether the action returned to Fleet or displayed an error.

Use Get support and report a portal issue if the missing information persists.

Next: manage the actual maintenance

When the records are available, follow Aircraft maintenance: keep your airline flying to choose a check, find workshop capacity, review costs and confirm completion.
