Enter Performed Interval Based Maintenance

Explanation

This activity is used to enter interval based maintenance activities that have been previously performed on the serial structure, but not yet been logged in the system. You can enter this information for both components that have not been logged in the system before, and components that have existing, but not complete, historical data in the system. It is possible to adjust the values that were recently entered so that several records do not appear in the log by mistake. The Serial Initialization/Interval Maintenance tab displays all possible maintenance activities, not only those for which maintenance events have been created. The maintenance plan controls what is visible for each selected serial. For more information, refer to the online help file Interval Based Maintenance Programs. Note: It is important to be careful when registering a start or updated value for a serial, since these values are important for result calculations like the due date calculation of interval maintenance.

You cannot record an overhaul that has occurred between existing operational log records or where the latest operational loggings have not been completed. However, as an exception, you will be allowed to report an overhaul prior to all the recorded operational loggings. It is necessary for all the logging dates of the latest logging to be the same for all operational parameters of the serial before you can report and overhaul from the Serial Initialization page.

The different ways of entering performed interval based maintenance depending on how the maintenance plan has been set up, is described in the following subsections. Each subsection will have a defined scenario containing at least what the maintenance plan looks like. In addition to the maintenance plan, the average operational values (per month) and the current operational log values will influence the result of entering the performed interval based maintenance. All the different subsections are referred to as different cases:

Common steps relevant for all subsections

  1. Open the Serial Initialization page, and search for the necessary serial structure.
  2. Click the Interval Maintenance tab, and observe the maintenance codes that appear automatically.
  3. For the maintenance event to be logged, enter a value in the Value At Maintenance field for the primary operational parameter in the upper list.
  4. In the lower list, enter a value in the Value At Maintenance field for the other operational parameters.
  5. Repeat steps 3 and 4 for other maintenance events to be logged.
