Modeling component maintenance

Component maintenance refers to work that requires the removal of a component or a part from a top level asset (aircraft or other assembly) or from its immediate parent component in the equipment hierarchy. This work is completed in a maintenance shop location by technicians who do not work on the aircraft. Replacement requirement definitions (REPLs) are used to remove the component from the aircraft, assembly, or parent component.

Task definitions for components are associated with any of the following:

  • Configuration slots with config classes of: sub-assembly (SUBASSY) or tracked (TRK).
  • Part numbers with inventory classes of: Kit, Batch, Serial-Controlled, and Tracked.

Maintenix provides the following features to address the particular aspects of component maintenance:

  • Automatic creation of work packages for components and replacement tasks.

    When a component is removed from the top-level asset, and there is a maintenance task initialized for the component that specifies the component must be removed from the asset, Maintenix automatically creates a component work package for that task. When maintenance tasks are initialized against a component that is installed on an asset, Maintenix creates replacement requirements on the asset, so that the component is removed from the asset.

    When a maintenance task is initialized for a component on a configuration that has multiple positions, Maintenix creates the component work packages and the required replacement tasks for each of the positions. The name of the component work packages includes the position name.

    Users can also create the component work packages and replacement tasks manually.

  • Ability to identify component tasks that should be performed at the next convenient opportunity, but that are not critical to the point of preventing the use of a component when the tasks are not completed by their due date. This feature is called Next Shop Visit.
  • Enforcement of the order in which the sub-tasks of a component requirement must be performed, and the ability to route components to different specialized shop locations as needed.
  • Creation of repair orders for component maintenance work to be performed by external vendors.

For repairing faults and managing ongoing maintenance related to fault repairs, you can use repair reference requirement definitions.
