The Configuration Management Service (CMS) is an automated process that evaluates and validates component removals or installations during aircraft maintenance, ensuring part changes align with the configuration in Maintenix. This process guarantees that only applicable and approved parts are used, maintaining the basic airworthiness of the airplane.
If CMS determines that there is a problem with the removed or installed inventory it issues a configuration warning. For the complete list of scenarios for which warnings are issued, refer to the CMS API Guide published with Maintenix documentation.
When recording work on a task or fault in Line Maintenance Execution, a technician fills out all the information required on installed and/or removed components to certify the completion of maintenance work. On signing off on the task/fault card, the status of the work task changes from In Work to Completed. At this point, the information related to the component change, installation, or removal is sent to CMS for validation.
If the component change is split over two task cards, one for removal and another for installation, the technician must complete the removal card before the installation card in order to avoid CMS issuing a warning message.
If a technician is deferring a fault that has part installation or removal records, the information related to part changes is sent to CMS for validation.
The CMS is triggered when the fault status changes to Deferred on the Fault Details page.
During the time from task completion or fault deferral until CMS validation, a yellow banner is displayed on the Task Details and Fault Details pages to indicate that the CMS validation is still pending and that at least one part change has not been validated.
When the CMS validation has been completed and CMS determines that there is a problem with the removed or installed inventory, CMS sends configuration warnings to Line Maintenance as follows:
If all the part changes have been evaluated and at least one found a configuration warning was identified on a task, the warning appears as a red banner on the Aircraft Turn Details, Task Details, and Fault Details pages, with detailed warnings issued by CMS displayed on the Task Part Changes or Fault Part Changes page on the Line Maintenance Execution mobile application, IFS Maintenance for Aviation. On the Line Maintenance Execution web application, the detailed warning can be viewed on the Part Removals and Part Installations tabs of the Task Details page, by expanding the row with the configuration warning. If a configuration warning is displayed for a task or fault, it is also indicated via the Configuration Warning badge on the Work Tasks page/tab for the task.
Before releasing an aircraft to service, on the Release Aircraft page, the Configuration Warning field takes on values as follows:
If configuration warnings were raised, the line technician can return to a specific task/fault card, review the reason why the warning was displayed and the MOC or the supervisor can decide to release the aircraft to service or fix the problem according to the definitions of the airline.
